    • I have oa in both knees with most of the pain on the outsides of each knee. Which product should I order and where should the hinges be placed?

  • MADDIE at 9/6/2016 5:50 PM

  • what is the difference from the reaction knee brace the the oa knee brace at 8/19/2016 5:32 PM
    • what is the difference from the reaction web knee brace and the oa knee brace
    • The OA Reaction Knee Brace has a specialized hinge to offload some of the pressure from one damaged side of the knee to the opposite side, providing more joint space for the injured side. The Reaction Web Knee Brace is more for general knee pain that is not associated with osteoarthritis.
  • Brett at 8/19/2016 3:46 PM
    • Pain on inside of left knee, what medial/lateral do I need?
    • If your pain is on the inside of the left knee you will need a medial left DonJoy OA Reaction Web Knee Brace.
  • Joyce at 8/12/2016 1:07 AM
    • Ready to order But confused! 22 1/2' Thigh .19' Knee and 18" calf.. I have OA " bone on bone" with knee pain in knee cap and back of knee...I have 0 interest in knee surgery...Please help me decide??
    • The DonJoy OA Reaction Web Knee will unload the affected side of the knee , however, if your pain is more generalized, I would suggest the Donjoy Reaction Web Knee, this brace helps to reduce pain in the front of the knee around the kneecap, by acting as a shock absorber, see here: https://www.betterbraces.com/donjoy-reaction-knee-brace
  • Angie at 7/31/2016 5:05 PM
    • I have osteophyte + OA, and currently my left leg has been popping backwards from time to time while walking. I am looking for a knee brace that would help me stabilize my leg in order for me to walk without falling. Is this DONJOY OA Reaction WEB Knee Brace product sufficient & supportive enough for my knee problem? I need something light for I sweat but in the same i need one that strong enough for support...please recommend!
    • The DonJoy OA Reaction Brace would not address your hyperextension issue. In order to find the right brace for you, it would be best for you to call and speak with a Product Specialist, so we can get more information on your diagnosis.Please call 1-800-553-6019.
  • Martha Henrickson at 7/31/2016 6:58 AM
    • I have a torn moniscus in my right knee, and arthritis in the right knee, the pain is on the right side of my right knee. (and also pain up my leg into the gluteus max and min...The DonJoy OA reaction brace was suggested by sports med. doctor...not sure which side that button should be on? I measure 22 1/2 " (thigh 6" above knee cap).. Not sure which side the button should be on??? thank you,,Martha
    • If your pain is located on the outside of your right knee (lateral) then you would select the option that says Medial Left or Lateral Right. So when you get the brace the condyle will sit on the inside of your right knee to push it laterally, outwards, to relieve the pain on the outside of you knee. Based on that measurement we would suggest the Large.
  • Rafael Saucedo at 7/24/2016 8:11 PM
    • My measurements are
      Thigh: 17"
      Knee: 14"
      Calf: 14 1/2

    • Based on the measurements you provided we will recommend you go with a medium.
  • Kenny at 7/21/2016 6:57 AM
    • OA pain on outside of my left knee. Thigh 24", Knee 19 1/2", Calf 19. Medial or lateral and what size would you suggest for the Reaction Web?
    • You would be a size XL, and select the option Medial Right/Lateral Left.
  • Kyra at 7/2/2016 5:50 PM
    • Simplifying my question.....if I have a patella tracking problem because my lower leg bone is positioned to the outside of my knee, causing Patellas to shift to the outside of my legs....and I have arthritis in both (left knee is missing cartiledge)....what kind of knee brace would be best? I'm diagnosed with osteoporosis. I'm ready to purchase, just waiting for a reply.
    • The patella tracking issue you are having would be better treated with the DonJoy Tru-Pull Lite, https://www.betterbraces.com/donjoy-tru-pull-lite,which, offers support on the lateral side to help the patella track correctly.
  • Nancy Nesvet at 6/26/2016 6:59 AM
    • 1) Is it expected that the under sleeve is always worn under the brace? 2) How tight is the brace supposed to be? 3) Unfortunately have not found the brace to be very comfortable - Is it possible it is not the right brace for me or do I need a better fitting/adjusting 4) I have the left knee brace and the inner lower portion of the brace digs into my leg
    • It is a personal preference when it comes to the undersleeve. The undersleeve helps with any chaffing while wearing a rigid brace. The brace should be snug on you but not blood constricting. Make sure you are putting the brace on while you have your leg in a 45 degree angle. If its not comfortable, you might want to double check your measurements. Make sure you are standing up, shoulder width apart, legs slightly bent and muscles contracted while taking the circumference at the knee center, 6in above the knee center onto the thigh, and 6in below the knee center onto the calf.
  • George at 6/25/2016 7:26 AM
    • I severed both quad tendons 2 years ago. I am now suffering from swelling, a lot of pain in my left knee. PT tapes me similar to the webbing on your design. I now have anterior arthritis on my left knee with a lot of pain. Do you think this could alleviate some of my problems?
    • The DonJoy OA Reaction Web Knee will unload the affected side of the knee , however, if your pain is more generalized, I would suggest the Donjoy Reaction Web Knee, this brace helps to reduce pain in the front of the knee around the kneecap, by absorbing forces on the knee and dispersing them away. https://www.betterbraces.com/donjoy-reaction-knee-brace
  • Frank at 6/23/2016 2:31 PM
    • Pain is on the inside of my left knee. Which brace should I order? How do I tell which size to order?
    • For the OA Reaction Web Knee you'll want to order a medial left brace. The "medial" refers to the area where you have pain, and the unloading hinge will then be located on the lateral side of your leg to relieve the medial pain. Under the pictures of the brace on the website there is a section called "size chart and fit help." Please refer to that chart in order to take the correct measurements of your knee for sizing. https://www.betterbraces.com/donjoy-oa-reaction-web-knee-brace
  • Dianne at 6/20/2016 6:28 PM
    • Right knee - OA pain centre and outside. Measurements = 26.5 thigh; 18.5 middle of knee and 19 calf. What size brace would you recommend.
    • Based on those measurements we would suggest the XL. For pain in the Right knee towards the outside (lateral) we would suggest you choose the option Medial Left or Lateral Right. When worn on the right knee the DonJoy Condyle Hinge will sit on the inside of the knee to push towards the outside (lateral) to create the offload, and take the pressure off the outside of the knee.
  • Tom G at 6/19/2016 7:17 PM
    • I had ACL surgery 20 years ago on my right knee. I am getting arthritis and bone on bone in my right knee. When ordering the OA Reaction Web Knee brace for my right knee should I order the Medial or Lateral fit. My pain is on the medial (inside) of my right knee.
    • Place your order based on your diagnosis or your affected side of knee. If you have Medial OA, select Medial when placing your order.
  • Jose at 5/10/2016 9:27 PM
    • I have pain on the center to right side of my knee. Which option should I get?
    • The right side of your right knee is considered lateral and the right side of the left knee is considered medial. Hope this helps
  • Doris at 5/2/2016 1:41 PM
    • It appears that I would want the left medial right lateral brace for pain in right knee on inside. My question is size. My thigh is 25, knee 17.5, but calf is 16. Will the X like fit and stay up?
    • With pain on the inside of your right knee you would want the right medial/left lateral brace. And based on your measurments you will have to go with the XL based on the thigh and knee center. You will have to tighten the calf up as much as you can
  • Gary at 4/30/2016 8:27 AM
    • Will the lateral DONJOY OA REACTION WEB KNEE limit knee varus?
    • No you will want to get the Medial OA Reaction so it will push on the outside of your knee. A varus knee usually has medial OA
  • Johnnie at 4/24/2016 11:49 AM
    • Is the OA Reaction Web brace only for Osteoarthritis sufferers? I see that some folks with medial meniscus tears have asked questions regarding it below - I like the non bulkiness of it as I would be using it for running and also for some everyday stuff where I need more support - I have medial meniscus pain on my left knee. I'd love to order this brace but don't want to spend this much if it's not appropriate for my knee issue.
    • Yes the OA Reaction web knee brace can unload the medial compartment where the medial meniscus is located. The unloading will help to decrease pain and prevent further damage
  • Ryan at 4/21/2016 9:46 PM
    • I have OA in my left knee all of my pain is on the outside and front of my knee is the OA reaction brace the right choice for me I'm an avid golfer and which option should medial/lateral option should I choose
    • Yes the OA Reaction would be an approriate brace for you to use. You would want to have the hinge side go on the inside of your knee to unload the outside. You would order the right medial/left latera brace
  • Roy at 4/18/2016 8:27 PM
    • I've needed a knee replacement since 27 years of age, 45 now and trying to put off total knee till 50. My pain is mostly in the knee joint on right knee. Outside right....Do I need the medial left lateral right? OA Reaction Web knee?
    • The correct brace for you would be the Left medial/ right lateral
  • Nikki at 4/16/2016 2:38 PM
    • My 14 y/o son is post-op 4 weeks right knee lateral meniscus repair and menisectomy. He has more than 75% left. However, the cartilage lying over the bone is torn. Unrepairable. He his knock kneed. The surgeon ordered a right lateral offloaded knee brace. I believe the OA adjuster was actually ordered. I want to make sure the company ordered the correct ibe. When it arrives, what should I expect? Like as far as the hinge? What should have been ordered?. He plays basketball. I also want to order the OA reaction for when he has P.E. or excercises. Is the OA reaction good for basketball as well or should he wear the OA adjuster during basketball?
    • The OA Adjuster will be a rigid knee brace the adjustment to unload the lateral side of his knee will be on the medial side. The OA Reaction is for mild OA so it may still be able to offer your son support for the lateral compartment of his knee during basketball.
  • Richard at 4/2/2016 12:40 PM
    • I have OA in my left knee pain in the inside of the knee what medical or lateral brace would I need?
    • You will order the left medial/right lateral and when you receive the brace the hinge will go on the outside of your knee
  • victor lesch at 3/29/2016 8:56 AM
    • Looking for a brace for the left knee. The OA seems to be the one. I didn't understand the Medial/Lateral option. When using a strap around the knee the best relief is pressure on the right inside space of the left knee joint.
    • Our OA braces will unload the affected side of the knee so the hinge will go on the opposite side of the knee that is bothering you to push towards the area and at the same time the straps pull above and below the knee to make space in that compartment that hurts. So in your case you would order the the Left medial/right lateral brace and when you received the brace the hinge will be on the outside of your knee to unload the inside
  • Dave at 3/27/2016 4:26 PM
    • I have OA in left knee and also a lateral meniscus tear. Measurements are Thigh: 20" Knee 16" Calf 16"
      What size and which set up do you recommend?
    • I would suggest the left lateral/right medial in a large size for your leg
  • katnunya at 3/26/2016 8:58 AM
    • I have right knee pain from the front center of my knee 1/2 circle to the inside, ending rear center of my knee. I am on my feet all day at work, and significantly overweight. Can you recommend the correct brace for me?
    • I would suggest the Reaction Web Knee brace. The brace helps to reduce pain in the front of the knee around the kneecap, by absorbing forces on the knee and dispearsing them away
      http://www.betterbraces.com/donjoy-reaction-knee-brace
  • Travis lee at 3/19/2016 7:43 PM
    • So I have torn my meniscus but for the oa reaction brace I don't know which option to pick. I don't remember what the doctor said but my right knee the meniscus is torn and the pain is on the left side of my knee if in looking down at it. Any recommendations
    • If you order the OA Reaction for the right medial/left lateral the brace should unload the inside of your right knee by applying pressure on the outside of your knee. The hinge would be placed on the outside of your knee and the pressure could unload and take pressureoff the inside
  • L b at 3/18/2016 3:19 PM
    • I've had many knee surgeries for acl repair as well as partial meniscus and cartilage removal. I still run long distance and play soccer. I want a brace that will give me relief from my arthritis pain but most of it is medial meniscus pain although I'd benefit from just an OA brace. Which brace would be best that I can use daily and for sports if I have all over OA but significant medial pain?
    • The OA Reaction will provide overall pain relief to the front of the knee with the webing design of the brace and if you were to order the Brace for the medial compartment then you can unload the medial compartment and give some mild relief from that sid of the knee. this brace is low profile ao would be great for a runner
  • Darren at 3/17/2016 11:39 PM
    • I play football and im a offensive lineman and i was recently told i have arthritis in on the side of my left knee. Most of my pain comes from the inside (right side towards the front) of my knee and im looking for a sleek knee brace to help with my movement. What type of brace(s) do you recommend?
    • For your situation the best brace would be the Custom Defiance OA. The brace is made of carbon fiber so it is strong enough for contact sports but is custom made for your knee only and can be made with a OA offloading hinge to unload the inside of your knee. http://www.betterbraces.com/donjoy-defiance-iii-custom-knee-brace This brace is worn by professional football players. The OA Reaction will provide mile offloading for the inside of your knee but will not offer much protection from contact during football.
  • Shirley K at 3/17/2016 9:13 AM
    • Am looking at a brace for my right knee - pain is allover the knee, but maybe worst on the inside but with swelling on the right side (!) Which medial/lateral option would I need?
    • You want to order the right medial/left latera brace and when you get the brace the hinge will go on the outside of your knee
  • Phyllis at 3/16/2016 7:10 AM
    • If you have knock knees, should the cup on the brace be on the inside of the knee, so as to push out?
    • Yes that is correct
  • Christy at 3/13/2016 12:32 PM
    • I have mild arthritis in both knees, but looking for a brace on the left. I also have fibromyalgia with very tender points on medial aspect. I am worried that anything pressing on that tender point will make the brace unwearable. Not sure which side is more painful arthritically.
    • Whichever compartment you choose the hinge or upright will be on the opposite side so if your knee is very tender over the medial aspect you would want to get a brace for the medial compartment and the upright will go over the lateral side
  • Shayne at 3/9/2016 4:59 PM
    • About 4 weeks ago i had was pulling a subzero refrigerator (1200lbs commercial style for high end homes) up some steps while trying to step backwards up the step i heard the infamous pop as my knee buckled and the fridge and handtruck came tumbling down on to my knee, i have a chipped knee cap, and a severe bone contusion. The way my knee was bent i swore i had ligament damage and the pain is still horrible on the outside of my left knee. Doctors states no damage to ligaments or meniscus, just lots of rehab and ice, for a couple weeks/months. I still feel instability side to side and sorta like jumpers knee pain. It also feels like it wants to give way after short walking trips (10-25steps) what would be the best brace for me... considering the Dr's finds (i have KP insurance so i cant really goto another dr)
    • Based on what you are saying I would suggest a hinged knee brace to use until your knee heals to offer some support. The Economy hinged knee brace provides general support to the knee and will protect side to side movement.
      http://www.betterbraces.com/donjoy-economy-hinged-knee
  • Jaks at 3/9/2016 7:22 AM
    • Ordering for my husband. He has OA in both knees (still too young for replacement) but more so in the left knee. When I asked him, he said if he had to pick a side that hurts more, he says the outside of his left knee is the most painful. Can you clarify which brace is recommended, specifically Medial L/Lateral R or Medial R/Lateral L? He wears a brace daily (is on his feet on concrete most of the work day) and especially is looking for pain relief during golf. Thanks!
    • For the left knee: Oa Reaction Right medial/left lateral and the hinge will go on the inside of his knee pushing towards the outside of his knee. For the right leg he would get the left medial/right lateral
  • Laurie at 2/28/2016 5:45 AM
    • Size?
      Thigh. 18
      Knee. 16
      Calf. 14.5
    • Based on these measurments there is no way to have a perfect fit. The only suggestion is to order the medium but the knee will be a little tight.
  • Candice at 2/10/2016 7:09 PM
    • I am interested in getting this brace for my Aunt who has bone on bone in both her knees. She lives in the Caribbean so i will have to buy it and ship it abroad. I am concerned about the staps wearing out after a short while given the reviews that i read on your site. What is your return policy? has this problem been resolved in the design? Thanks
    • The velcro has been changed on this brace quite a while ago to address this problem. We also have something that can be purchased to help with the velcro adhearing. The product is call High cycle Velcro.
  • Mr B at 2/10/2016 6:47 AM
    • I had surgery on my left knee for a meniscus tears on the medial side. I also have osteoarthritis issues. Will be orderring an OA reaction but want to confirm which brace I should get
    • You would order the left medial/right lateral brace and when you receive the brace the hinge will go on the outside of your leg.
  • Phyllis at 2/10/2016 12:32 AM
    • Both my knees are arthritic and are knock knees. I am 75, but still hike and do workout. The knees hurt when I bend them with feet pointing outward in Tai Chi Class. What do you recommend.
    • I would suggest the Reaction Web Knee Brace. The Reaction absorbs forces on the knee to decrease pain in the front of the knee
  • Sandra at 2/7/2016 2:52 PM
    • I have arthritis in both my knees. The doctor has never really said if it is medial or lateral. All I know is that he does my cortisone injections on the outside side of both knees. I am looking at a definite knee replacements in the future, according to dr, but we are trying to postpone due to my age (52). I would like to try braces to relieve pain rather than take the heavy drugs they want to put me on. Which braces do I order?
    • You can try the OA Reaction Web knee Brace and it sounds like you may need to offload the lateral or outside of your knee. The OA Reaction web is for mild OA but is low profile and not as bulky as some of our other OA braces. If you were to order this brace the hinge would be placed on the inside of your knee to push in the direction of the outside of your knee. The brace offloads this way by trying to make a little space between the bones.
  • tamara s at 2/3/2016 6:35 PM
    • it is my right knee inner knee cap that has a little cartilage worn away. do I need medial right or medial left? I am confused on what this means?
      thank you,
    • You will order the right medial/left lateral brace and when you get the brace the upright will go against the ouside of your thigh
  • Nathan Brown at 2/2/2016 8:07 AM
    • SO # 1183512 #11-7426-1 19/11/2015
      Velcro lost its adherence
      Do i need high cycle velcro ?
    • yes and the brace is under warranty still
  • Legacy Lou at 1/30/2016 5:47 PM
    • I had surgery on my left knee medial meniscus where a flap was removed. The right knee medial meniscus now also has a small tear. There is pain in the area of both medial meniscus'. Which braces do you recommend for hiking, running, cycling?
    • The OA Reaction for the medial compartment on both braces should help to decrease that pain by offloading it. The hinge would be on the outside of your knee and it would push the knee towards the medial side to increase space between the bones. The space should decrease pain in that area
  • J J Paul at 1/15/2016 6:54 AM
    • I have two OA reaction knee braces and the velcro is breaking down. The braces are otherwise in good shape. Any solution? Thanks.
    • There is a product that is available to help reinforce the Velcro for the Reaction and OA REaction Web braces. It is called High Cycle Velcro and can be purchased by calling customer care
  • Jeff at 1/13/2016 8:10 AM
    • I want a brace for each knee - I dont understand the choice of medial/lateral
    • The medial and lateral corespond to whether its the inside or outside of your knee that is effected. Medial is inside and if that is the side that is the OA efected comparment then that is the brace you want. The hinge will be placed on the opposite side of the affected compartment
  • Laura at 1/11/2016 11:13 AM
    • Sorry, me again. The upright is the portion of the brace without the silicone pad or with the silicone pad?
    • The upright is the rigid part that has The red pads and silicone on it
  • Laura at 1/11/2016 8:24 AM
    • I think I may have ordered the wrong brace. I have OA and cartilage missing on the outside of my right knee with pain there. I ordered the left medial right lateral. Right or wrong? Thank you.
    • You ordered the correct brace. The upright is going to go against the inside of your knee to push towards the lateral side to unload it.
  • john at 1/9/2016 8:09 AM
    • I am 48 years old 6 weeks ago I tore my acl,mcl, and meniscus, plus I have been dealing with artritis. the mcl now healed and the bone and joint is not operating at this time. I am returning to work in one week, I am on my feet all day and need something comfortable to go under jeans. would this brace work for me?
    • I would suggest something to give the ACL some support and protection such as the Playmaker II knee brace. The brace should be able to fit under clothes. http://www.betterbraces.com/donjoy-playmaker-ii-knee-brace
  • Larry Warnick at 1/3/2016 1:58 PM
  • kurt at 1/3/2016 9:31 AM

    • You would order the right medial/left lateral brace and when you receive it the hinge will go on the outside of your knee.
  • Walter at 12/20/2015 8:32 PM
    • Hi, my right knee MRI shows: frying of the free edge of the posterior horn of the medial meniscus. Mild chondromalacia with mild medial joint space narrowing (I have bow legs). Old history of Osgood-Schlatter disease but without tendinosis of the patellar tendon. My sport's doc gave me this OA web brace but with hinges on my inside of the right knee. So I suppose this is wrong. Pls tell me which brace is right for me. My size: tight/knee/calf is 19/14/14" - medium?
    • If you are bowlegged and need a brace for the medial compartment you will need the right medial/left lateral knee brace and the hinge will go on the outside of your leg. Based on your measurements you would fit into the medium brace
  • Matt at 12/11/2015 7:33 AM
    • Your reviews on Amazon are not so stellar. The complaints are universally about the velcro failing after a few weeks, brace breaking, sizing being too small and the sleeve being too small. Have you addressed these issues? Otherwise everyone seems to love the brace when it is functioning as advertised. I would buy it if the workmanship was better.
    • Since the brace first was launched we have made improvements to the brace and still continue to make improvements to offer the best product we can. Our braces have a six month warranty for manufacture defects so we will replace the brace if it has become defective for reasons other than usual wear and tear.

    • I have moderate OA on my right knee and it hurts inside the knee. Which brace should I order?
    • You will want to order the right medial/left lateral knee brace. When you receive the brace the upright will go on the outside of your knee so it will unload the inside of your knee.

    • Hi confused on the brace option I need....I have mod to adv. OA, multiple surgeries. no pain cycling but XC skiing is becoming painful. Right knee pain, mostly anterior around the 1 o'clock position laterally around the out side to the 4 o'clock position Anterior to posterior mostly . thinking about the OA Reaction Web Knee brace . would you recommend this brace and which fitting option do I need
    • Dave
      If you have pain on the lateral side of the knee you will pick the right lateral/left medial. If the pain is on the medial side you will pick the right medial/left lateral
  • Christine at 11/12/2015 3:52 PM
    • I have accident at left knee. I want to buy silicon web... But in choose option Is medial left ?
    • If you have pain on the inside of your knee then order the Left medial/right lateral. If your pain is on the outside of your knee then order the left lateral/right medial.
  • Dave at 11/10/2015 9:22 AM
    • I've been dealing with knee pain for almost a year (right knee at the start). I have seen an orthopedic surgeon, and have been diagnosed with arthritis, and bone-on-bone (no cartilage). In the past year, I have undergone two series of shots with an artificial cartilage replacement and have experienced some relief. During my last appointment (initial series of three shots in March), I had my left knee x-Ray ed, and I received a similar diagnosis on my left knee that I had received with my right knee. In September, I went through a series of three shots administered with the artificial cartilage on both knees. I had hoped that I would have received some additional relief. Not so. I'm now considering purchasing the OA Reaction Web Knee brace (left medial/lateral right) for my right knee. Is this the brace that I should consider? If successful, I'll probably purchase a brace for the left knee as well.
    • Dave
      The OA Reaction is for mild OA and might give you some relief. If you have pain on the inside of your knee you will want the right medial/left lateral and the hinge will sit on the opposite side of the knee in which you have the OA
  • Angie at 11/9/2015 4:24 PM
    • I have been diagnosed with moderate to severe arthritis in my left knee. To touch, the knee is most tender on the right/inside of the leg. Walking is painful. Would the OA Reavtion be a good match? And, if so, I don't know which medial/lateral to order. Thank you!
    • Angie
      The OA Reaction is for mild OA so it may give a little relief to your knee. You would want to order the left medial brace and the hinge would be on the outside of your knee pushing to unload the inside of your knee.
  • Kathryn at 11/9/2015 12:26 PM
    • I bought a right medial medium OA Reaction. I find that the brace slips down over my kneecap as I walk. Does that mean I'm not tightening it properly? The size chart indicates that medium is correct.
    • Try tightening it more at the bottom than the top
  • Peggy at 11/5/2015 5:49 PM
    • I have right knee OA. Do not have a knee cap. Have had osteotomy to change weight baring point to medial side. Lateral side has had an allograft that is doing well. Medial pain is the current challenge. Tried a hinged wrap around brace, without a knee cap, the brace kept falling down to my ankle no matter how tight I adjusted the straps. Any advise as to what brace might be best for my unusual situation?
    • Peggy
      The OA Reaction web knee brace should work for you, however most soft knee brace anchor around a kneecap. Since you do not have one, you may need to go to a rigid knee brace that doesn't rely on the kneecap as a anchor point. If the Reaction doesn't stay up you may need to look at something like the OA Nano

  • PAMELA at 10/28/2015 1:38 PM
    • I just got my brace and it is for my right knee. I have OA in the right knee. I ordered a Medial right/lateral left. I'm confused. I thought that the "hinge" was on the outside of the knee. It's not, it is on the inside of my right knee. Is that correct?
    • Pamela
      If you ordered the right medial and it is for your right knee the hinge should be on the outside of your knee. Our braces push towards the affected compartment. In your case the hinge is on the outside pressing towards your medial or inside of your knee. The push shifts the bones to make space on the inside of your knee.
  • Brian at 10/18/2015 1:18 PM
    • I have mod-severe medial OA with severe patellar and mild to mod lateral OA bilaterally. Bone on bone medially and patellar. Would any of your braces be helpful? Thanks for your advice.
    • Brian
      All of our OA unloading brace will only unload one compartment at a time. Since you have OA in both compartments you would want to get a hinged knee brace for general knee support such as the Playmaker II with a patellar donut. http://www.betterbraces.com/donjoy-playmaker-ii-knee-brace The OA Reaction wold provide some support to bothe the medial compartment and the patella, but may put pressure on the better of the two compartments, the lateral.

    • 46 years old and regular short distance runner. I had ACL and Meniscus surgeries almost 2 years ago. Doc says I have arthritis in the knee now but otherwise good to go. I am a jiujitsu instructor and wish to continue training. Looking for a brace that is low profile (I can wear and not injure others) and provide support I need - would you recommend the OA Reaction brace or the Reaction brace? I don't wish to crush my opponents with the brace, just get support and lessen pain - thanks!
    • Neal
      Either brace would be what you are looking for. The difference is that the OA Reaction has a singe hinge on the brace so a harder structure that may injure others. You may want to try the regular Reaction first and see if that provides enough pain relief for you.
  • Wanda at 10/8/2015 6:53 AM
    • I have bone on bone OA on my right knee and recently had a left hip replacement and can't take time off work again for another surgery. I travel in my job so walking through airports and convention centers is very painful. My surgeon gave me a Donjoy Economy Hinged Knee Brace but it is so bulky it can be seen under nice dress pants. And since my right knee is turning in towards my left knee when I walk this brace rubs against my right knee. Would the Reaction Web Knee Brace be a lighter better choice?
    • Wanda
      The OA Reaction Web Knee brace will be a lighter lower profile brace that should give you more relief than the economy hinged knee. There is a singe upright and hinge that will be located on the inside of your knee that will help to push the knee towards the outside. The brace is for mild OA so it may not take all of the pain but it should be better than what you are currently wearing
  • Bette J at 10/4/2015 6:20 PM
    • What knee brace would yourecommend for an active 90 year old woman whose right knee is turning in and has arthritis in the same knee? She is in a lot of pain.
    • Bette
      I would recommend either the OA Reaction Web Knee brace for the right lateral leg or the OA Lite knee brace for lateral compartment OA. http://www.betterbraces.com/donjoy-oa-lite-osteoarthritis-knee-brace
  • Michael at 9/24/2015 7:47 PM

    • I had ACL and Meniscus surgeries 2 years ago, am 46 years old and remain active. I need a brace that fits well, and allows me to run and train in martial arts every day (competitive, but not professional). I need a brace that I can wear and won't injure my opponent in kicks as well - I have a heavy duty donjoy brace, but it is too bulky and I injure my opponents when wearing it. Thank you for any guidance!
    • Neal
      Unfortunately if you want a brace to support the ACL only a brace with a hinge will do that. Other than what you are currently wearing the Playmaker II knee brace is a soft hinged knee brace. http://www.betterbraces.com/donjoy-playmaker-ii-knee-brace
  • Wasif at 9/22/2015 8:57 AM
    • I am looking to get this brace for my dad who has severe pain in his left knee. He also has a bit swelling around his knee cap. I want to make sure i order the right brace and right size for him.
      His measurements are:
      Calf: 16"
      Knee: 18"
      Thigh: 20"
    • Wasif
      You will want to get the large size but you will also need to know which side of the knee needs to be unloaded. Usually the painful side of the knee will determine that.

    • Jeremy
      With your history you might want to wear a light hinged knee brace to give you some general knee stability. Either the Don Joy Economy hinged knee brace or the Don Joy Performance Bionic Knee would be good choices. Bothe are hinged knee braces.

Currently I can bend it about 90% , but have strong pain on the inside of my knee.I have mild arthritis in this knee. I like how sleek this brace is, that was the main reason it drew my attention. Please let me know! As well as which option would I get, if I am using it to as a patella stabilizer as well.

      Thanks!
    • Carly
      The Reaction web Knee Brace is a great brace for patellofemoral pain and dysfunction, but since you have had several dislocations I fear it may not be the right brace for you. Take a look at the Tru-Pull Lite knee brace. This brace is made specifically to help prevent patellar dislocation. The brace is alighter version of our other brace called the Tru-Pull Advanced system. The brace is much smaller and the material is light wieght. http://www.betterbraces.com/donjoy-tru-pull-lite
  • Robyn Gomez at 8/28/2015 12:44 PM
    • Inside of both knees are bone on bone. Need help ordering correctly. Based on the answers to questions of others I believe I should order Medial Left/Lateral Right for my left knee. Would it be Medial right/Lateral left for the right knee?
    • Robyn
      Correct you will want the medial left/lateral right for the left knee and the medial right/lateral left for the right knee. When you recieved the braces the hinge should be on the outside of the braces, pushing towards the affected compartments
  • Lee at 8/28/2015 9:30 AM
    • My pain is on the center and top part of my right knee and on the inside. I have very little cartilage left. The pain worsens when I go up and down stairs or squat. Would the OA Reaction be the best option for me? If so, just making sure I should order the Medial Right/Lateral Left?
    • Lee
      The OA Reaction might give you some relief. YOu would want the right medial/left latera brace. the upright would be on the outside of your knee pushing towards the inside of your knee.
  • Mary Edwards at 8/26/2015 8:44 AM
    • I have a history of lateral meniscus removal, knee pain and arthritis. It is worse in my left knee and my ortho doc recently ordered this brace for me for the left knee. I received the brace and the hinge with the cusion is on the medial side of the brace (when put on the left knee). My issues, are more on the lateral side of my left knee. Did I get the correct brace?

      thanks!
    • Hello,

      Thank you for Contacting Betterbraces.

      You did order the correct brace. If you have lateral OA the brace that adjusts will be on the medial side. The medial hinge pushes in to open up the joint space on the lateral side of the knee.

      Please contact us at 800-553-6019 for additional questions.

      Have a Great Day.
  • Miriam at 8/22/2015 3:16 PM
    • After hip revision (replacement of a replacement) surgery, my right leg is knock-kneed; it gets worse when I walk on it. My abductor is strong, but sore, likely because a wire from the surgery is rubbing against it.
      My therapist has recommended a DonJoy OA Reaction web knee brace.

      My questions:
      1) Is this the best solution to permit me to walk freely, without injuring myself further -- and, with luck, help me to recover?
      2) If so, what model should I get: the right medial, or . . . ?
      3) My measurements are:
      Thigh 6" above patella, 16 1/2"
      Knee center: 15"
      Calf 6" below patella, 14"
      What size would you recommend?

      Thank you for your help.
    • Miriam
      You would want to get the right lateral brace. This will have the hinge on the inside of your knee causing a push to the outside of your knee. Looks like a small should fit
  • Jesper at 8/20/2015 9:16 AM
    • Since 50% or more questions are about which brace to use (left / right / inside / outside, may I kindly suggest you begin to use those words instead of medial right / lateral left etc? I would be more comfortable making a purchase based on explanations I immediately understand.
      In the meantime: I have OA pain on the inside of my left knee; which brace is right for me?
      Thanks
    • Jesper
      That would be the OA Reaction Web Knee Brace Medial Left/Lateral Right. Which translates into this brace is for your left leg unloading the inside of your knee. We are happy to answer any questions about medical terminology which is what what use to describe the affectied compartments
  • Matthew at 8/8/2015 6:44 PM
    • I'm an active person that wants to continue to stay active with less pain. I had a R lateral meniscectomy, and since have torn through the articular cartilage on my femur. I received a bone plug via OATS allograft to repair, but the damage is done. Because of this, I now have OA in my R knee affecting the lateral side more than the medial. I have three questions:
      1. Does this brace provide full knee flexion up or aprox to what 0-140?
      2. Would this be the ideal brace for my condition?
      3. Would this be suitable for soccer/basketball/etc?
    • Matthew
      The answer to all of your questions is yes. You will have full range of motion in the brace and this would be appropriate for lateral OA.
  • Heather at 7/23/2015 10:15 PM
    • I have mild OA. What if my knee pain is primarily posterior and anterior - distal kneecap?
    • If you have mild OA located on both sides, there is no brace available for that. The offloading hinge has to go on the opposite of where the OA pain is located at. The hinge itself helps pushes inward/outward to help alleviate the pain that you are having from that bone on bone pain in your knee.
  • Denise at 7/18/2015 7:38 PM
    • I had recent knee surgery on my left knee for a meniscus tear and arthritis was shaved during the surgery. I find myself having pain throughout the knee on a constant bases. When following up with my doctor with an x-ray, it showed server arthritis still in the knee. This pain has limited my activity and ability to stand or walk for frequent periods. Would this brace help and which one should I order?
      Thanks!
    • Denise
      The OA Reaction Web Knee Brace is indicated for those with mild OA that is limited to one side of the knee, either meially or laterally(inside or outside). So to determine which brace to get you will need to know which side of the knee is the side with the OA and choose that brace. The single upright will be on the opposite side of the knee that has the OA and will push the knee in that direction to unload that compartment to decrease pain
  • Jeromy at 7/17/2015 7:17 PM
    • My wife has been told that she has OA in her right knee. If she pushes her knee to the center of her body, the pain is lessened. Which medial/lateral option do we choose?
    • If her OA is located on the outside part of her right knee, she will need a lateral right OA knee brace. If her OA is located is on the inside of her right knee, she will need a medial OA knee brace.
  • Cherry at 6/5/2015 6:18 AM
    • I am looking for a lightweight, non-bulky knee support for my 96 year-old father who has severe OA and knee pain. His leg bows out when he bears weight on it, and then the ankle rolls out, so I assume he needs a lateral condyle pad. I like the looks of the OA reaction web knee brace. Would this help him? He is not walking too far (5-10 min.walks), but needs more stability in his knee when he walks with his walker.
    • Yes, the OA Reaction Web Knee will help correct his varus issue. You would need to select the Medial option, and the brace will come with the hinge on the lateral side to help push the knee over to correct.

  • Catherine at 5/13/2015 4:39 AM
    • My osteoarthritis is focused on my patella, patellafemoral arthritis - extensive chondromalacia with some bone on bone with a misaligned patella. I do have the non-OA Reaction web brace, would this one be better or should I stick with the other one? I've no ligament issues, there is some tendonsis. My Ortho said it would be good to unload the front of my knee if possible. I don't think the regular Reaction Web does that. I do like the Reaction Web, though it is difficult to get it on properly - would the the OA version provide more benefit?
    • Catherine
      If your OA is under the kneecap then the regular Reaction would be the best for your knee. The OA Reaction is for someone who not only needs support around the kneecap but also has either medial or lateral compartmental OA and the brace unloads one of the other side of the knee. It sounds like you do not have that so I would stick with the regular Reactioin

The pain worsens when I bend greater than a 90 degree angle (like in a squat). Would the OA Reaction be the best option for me. If so, which one would I order....the RL/LM? Thank you!
    • Michele
      Yes the OA Reaction would be a great choice for you. the brace will offer pain relief around the patella and you can order the left medial/right lateral brace to unload that inside of your knee. When you receive the brace the hinge will be placed on the outside of the leg.
  • Nick at 4/17/2015 6:20 PM
    • I am a very active older male with significant (bone on bone) arthritis on lateral right knee, but so far minimal pain. I ski and hike all year and want to slow down the degeneration of my knee and put off a knee replacement. A brace was prescribed to unload the knee but the issue I have for skiing is that it is so long my ski boots hit it, so cannot be worn. Are the Reaction or OA Reaction short enough to be worn with ski boots.? Thanks!
    • Nick
      The OA Reaction is short enough to fit boots underneath it but it is for mild OA, so it may not provide enought unloading for that compartment that is bone on bone. Some of our other OA braces such as the OA Adjuster 3 are for severe OA, they also have a shorter calf frame.

    • I just got meniscus repair a month ago and I'm going through physical therapy right now and I'm wondering if the web brace would help me in basketball

  • Matt at 4/15/2015 8:59 AM
    • I'm not sure what option to pick for this brace. I have early OA in my right leg, and my pain is dead center of the knee - the patella - I don't know with of medial or lateral would be better?
    • Matt
      Since your pain is right in the front of the knee I would suggest going with the regular Reaction Web Knee Brace instead of the OA version. The brace will help to relieve that anterior knee pain you have and is also good for mild OA. http://www.betterbraces.com/donjoy-reaction-knee-brace
  • Rick at 4/8/2015 9:54 AM
    • I received my OA Reaction Web Knee Brace yesterday. The top of the undersleeve is constantly rolling down. Also, the brace tends to slip down lower than suggested when walking such that the top of the knee cap opening is mid-patella.

      Would you suggest the next larger sleeve size to address the sleeve rolling down?

      Any suggestions on adjusting either the top or bottom velcro straps to address the brace slipping down?


    • Rick
      Is it possible that you need a smaller brace? It sounds like maybe a smaller sleeve and brace will stay on better and not slide down. A bigger sleeve will not work.
  • Kelly at 3/30/2015 6:59 AM

I also have a torn meniscus on the left knee and have pain on and off on the medial side. Can I get a brace for each knee or is the OA brace the right one for either knee?
    • Kelly
      You will need to get a right medial/left lateral for your right leg and a left medial/right lateral for your left leg.

  • Cathy at 3/26/2015 6:09 PM

    • Cathy
      The OA REaction Web has a single upright and will unload one compartment of the knee. If the hinge is on the lateral side the brace will unload the inside of the knee. The webing design will give support to the kneecap and decreas anterior knee pain. I suggest you show the OA Reaction to your PT and ask them if this is sufficient for you.

      The hinge comes already pre-loaded with 3 degrees of offload. The upright is aluminum so it can be manually bent to apply more load if the 3 degrees is not correcting the pain on the opposites side of the leg.

    • I don't understand the option, or don't know which one to pick at best. Knee is bone on bone, broke off a spur or something. Need support to walk, want to lose the crutch. Replacement will happen eventually, but definitely not this year. Pain is mostly in front but not comfortable anywhere.
    • Mary
      Our OA braces are used to unload one compartment either the medial(inside of the knee), or the lateral(outside of the knee). The hinge is placed opposite of the compartment and ment ot push the leg into a more straight position which will unload that painful compartment. If you have pain on both sides of the knee then you may need to go with a regular hinged knee brace to give you general support. The Deluxe Hinged Knee Brace will give a more general type of knee support.http://www.betterbraces.com/donjoy-drytex-neoprene-deluxe-hinged-knee-wraparound-sleeve

    • Scott
      Yes this brace is for mile OA and you could get the right medial/left lateral brace. when you put the brace on the hinge will be on the outside of your leg. The unloading force will push your knee towards the medial side to help reduce some of that pain

    • I have severe VonWillebrand's disease which is a bleeding disorder where my blood won't clot without special medicine through an IV. I play softball and have a weak knee and mild pain. Are these braces recommended for playing sports? Will they start in place while running?
    • Ava
      This braces are made for sports and should stay in place

    • I have had several knee surgeries, but am struggling with arthritis pain (mostly medial meniscus). I have tried dozens of knee braces in the past, but have not been satisfied as they slide down my leg, are uncomfortable to wear all day, and cut into the back of my knee. I like the idea of the sleeve under to help for comfort, but will it still be secure and not slide down? Will this brace work for what I need it for?
    • Laura
      Yes this brace should work for the pain you are experiencing and this brace will most lilkley not slide down. You would want to get the brace that will unload medial.

    • DonJoy OA Reaction Web Knee the options i dont know which one would be the correct for me
      outside mostly pain on right knee mild to moderate depend on activity
      i have 2 problems from my knee
      knee cap need to be aligned (tracks inside lower left) and have moderate ware of cartilage lower left & middle groove under knee cap of my knee
      will this brace be good for me or do you recommend another one
    • Denny
      You will want the right lateral/left medial brace. The brace will have the hinge and upright on the inside of your knee and will push towards the outside to unload that compartment. This unloading will hopefully decrease some of the pain you are feeling on the outside of your kne and the webing will help decrease pain under the kneecap.

    • I have pain on inside of left knee, what would I order for the oa reaction knee brace?
    • Laura
      You will want the left medial/right lateral knee brace. When you receive the brace the hinge will be placed on the outside of your left knee.

    • I had a total knee replacement, left leg...... I have moderate to severe oa... I would like to know if this brace will help my knee pain and give me stability..... I have pain on the inside of left knee so I need to know which one to order? Medial left? Thanks, jacki
    • Jacki
      This brace is for mild OA so it might not give you any relief if you have moderate to severe OA, but you can try the brace to see if it does give enough offload. You will want to order the left medial if you would like to try the brace. We do have a 90 money back guarantee if it does not work for you.
  • Paul at 1/13/2015 10:49 AM
    • I have both a patellar tracking issue and early, mild OA due to medial meniscus tears. It seems that the Reaction Web is made for the former and the OA Reaction Web for the latter. Which would you recommend for my situation? I'm still very active and want something that will reduce the pain I get from playing tennis.
    • The OA Reaction Web Knee Brace is for those who have both patellar tracking and mild compartmental OA
  • Nik at 1/6/2015 8:34 AM
    • I have OA in my right knee, the knee goes inward towards my left knee. My leg looks bent from the front. Most of my pain is on the outside of my right knee. Which brace would I need? Lateral Right???
    • Nik
      You will want to get the lateral unloader. For the Reaction OA it will be the right lateral /left medial. When you receive the brace the hinge will be on the inside of your knee pushing to try to correct some of that "knock kneed"
  • Thomas at 1/2/2015 3:25 PM
    • Currently have a knee brace for left leg for OA that has an adjuster wheel to push from the inside knee(right side) out towards the outside of knee(left side). Would like to purchase the Donjoy OA Reaction Web Knee Brace. Would I need the medial right/lateral left to give me the same adjustment?
    • Thomas
      That is correct you would need the right medial/left lateral knee brace.
  • Gary at 12/19/2014 2:20 PM
    • my pain is the left (outside of my left knee) would I get the medial left?
    • Gary
      You will want to get the left lateral brace/right medial brace. When you receive the brace the hinge should be on the inside of you leg. Our brace unload the opposite side so if you need lateral unloading the hinge will be on the medial side.
  • Stephen at 12/17/2014 2:13 PM
    • Have mild OA of my right knee, the pain is on the inside. Which brace do I need to order?
    • Stephen
      The OA Reaction would be the right brace for you. the brace is for mild OA. You would order the right medial/left lateral brace
  • Melinda Whitman at 12/10/2014 3:40 AM
    • I ordered the Medial Left or Lateral Right for my Left Knee. The pain is on the right, inside of the left knee. The brace I received has the soft, silicone condyle pad on the left side of the brace. Was I sent the wrong one? Or did I order the wrong one?
    • Melinda
      If you have pain on the inside of your knee the hinge of the brace will go on the outside of the right leg. The hinge should be opposite the area that hurts to unload that medial side.
  • Chuck Dirienzo at 12/8/2014 10:13 AM
    • If the pain is on the outside of my right knee, what option do I choose?
    • Medial left/ lateral right
  • steve at 12/3/2014 11:41 AM
    • How is this different than last years & current reaction brace
    • Steve
      This brace has a single upright and hinge that goes on the opposite side of the affected compartment and unloads that affected compartment. So this brace will help either medial or lateral mild OA by unloading that side as well as providing the webing to decrease anterior knee pain. The original Reaction web does not unload compartments it only helps to decrease the anterior knee pain.

    • I have a 25 year old acl replacement on my right knee,have some arthritis and the pain is on the out side right knee , I snowboard and downhill mountian bike what brace would you recommend?the web brace looks like it would be great for snowboarding, thanks Jeff Fulton
    • Jeff
      The OA Reaction Web brace will not protect the ACL at all, but will help with mild arthritis Sounds like you might need a lateral unloading. A brace that will protect the ACL will be either the Playmaker II with the Fourcepoint hinge. http://www.betterbraces.com/donjoy-playmaker-ii-fourcepoint or the Don Joy Armor Knee Brace with Fourcepoint hinge. http://www.betterbraces.com/donjoy-armor-knee-brace-with-fourcepoint-hinge
  • Marion Godwin at 11/16/2014 12:44 PM
    • Can this brace be adjusted to lock the knee in different positions, i.e. 45 degrees
      90 degrees, etc. ?
      Thanks
    • Marion
      No this brace does not do that, it does not have metal hinges on it. The TROM Advanced is the only brace on this website that will do that. http://www.betterbraces.com/donjoy-trom-advance-knee-brace
  • Tia at 11/4/2014 2:23 PM
    • I have seen multiple comments about both of your web braces having poor Velcro quality and having to replace it within a few weeks. Have you fixed this problem? Other people have stated that yiu have yo practically cut off circulation to get it tight enough not to slide. Are there braces out there that will stay put and last?
    • Tia
      We have updated the velcro on the Reaction Web knee Brace, with a better velcro hook to address the problems people were having with the earier brace.
  • Neoma at 10/22/2014 2:31 PM
    • Hello,
      It was stated that this was for early cartledge degeneration of the knee. I have moderate to sever degeneration under the patella, where my knee hurts around my entire knee, will this knee brace help or is there one that would work better.

      Thank You
    • Neoma
      The OA Reaction Web Knee Brace is for those with mild compartmental OA in the knee. If you have OA under the kneecap the Reaction Web Knee Brace would be the correct brace for you. The Reaction's web design is going to absorb force on the fron tof the knee a dispearse the force away from the kneecap to decrease pain. http://www.betterbraces.com/donjoy-reaction-knee-brace
  • Jerry at 10/11/2014 5:45 PM
    • I don't understand the options. Does the specified option refer to the primary location of the pain? For example, my primary pain is medial left. Is that the option that I should choose?
    • Jerry if you have pain on the inside of the left leg then you are going to choose the left medial.

Thrilled With Brace, So Far.

Reviewed by:
Quality
I am thrilled with how it performs. With a complex tearing of the posterior root ligament, posterior horn and medial meniscus, I had a lot of pain and was most concerned that I be able to function uninhibited until I have an actual repair to my knee. That has proved to be the case, so far. Just two days after receiving the brace, I hiked aggressively under load over 14 miles in one day with no pain, and over thirty miles total in three days.

After one month of daily wear, the Velcro issues mentioned in other reviews have not materialized with mine, though I notice fraying of the fabric where the hooks occasionally come in contact with the edging material. I would certainly hope that if the fastening system rapidly deteriorates, that a replacement (like the sleeve) are available without having to purchase an entirely new brace.

Brace is very comfortable, I wear it every day at work. I'm an industrial electrician so I'm up and down and on my knees throughout the day.

My surgeon told me that there is no clinical evidence that an unloader brace provides any benefit for an arthritic knee. I can say that the Reaction Web brace has worked well for me. It has provided enough support to get me through this summer, though I will opt for knee replacement this winter.

The velcro closure could be better. My brace is 2 months old and I foresee sewing replacement velcro onto this brace in the near future

A great brace that uses a poorly made Velcro attachment.

This is my second OA Reaction Web Knee Brace. It works well for me. To echo other comments, I am very frustrated by the poorly made/designed Velcro attachment. I've had to replace that twice on my first brace. The quick fix sent to me didn't work at all. This brace would be 5 stars plus if not for this issue.

Not quite for activities I enjoy doing

I am not sure if there is not one better than the one I got. My brace helps with outdoor running but does not help as much (or enough) with dancing (west coast swing, hustle, salsa, batchata and free style). Dance of course has lateral and rotational movements and it maybe the case that the brace I have does not provide enough counter force against these for my minor meniscus injury. Having said that, I still get some protection with these types of moves but not enough.

Fabulous brace - I have tried many expensive Dr.-prescribed braces and none of them work well or stay in place without slipping down. This brace literally becomes part of me - I barely know it's there and my knee pain practically disappears. This brace provides me the stability and security to live life in a natural way. Thank you! Get the word out to the medical professionals! I agree that after some time there are velcro issues. I believe the company is working on this!

Love them but

Reviewed by:

I love the brace I needed it for both knees however I did not realize how swollen my legs were until I was wearing the brace for a week. I originally bought a large which fit fine at the time . I can still use it over pants but not under so during the recent sale I purchased a medium set & I am at the top edge for them & they fit properly. My only issue is the sleeves that cam e with the medium are way too small. I still need to use the large sleeves. Maybe, especially on reorder of braces, customers should be given a choice in size of the sleeves. Now I have size medium sleeves I can't use & when I need a 2nd set of sleeves I'll have to buy them & not use the ones that came with the new braces. I have tried wearing the braces without the sleeve but I end up with rashes & blisters.
