    • I been diagnosed with early stage avascular narcrosis of right knee, medial side - all pain on this side when i walk - just went finished a month on non weight bearing, but still painful - would one of your braces work for this condition? thanks
    • The DonJoy OA Nano Knee Brace is an adjustable unloading brace, which should shift the weight to the lateral side, relieving some of the pressure to the medial side.
  • JWLLMS at 7/14/2016 10:49 AM

    • I need to unload off of the medial side. Which option do I select? Medial? This is for my left knee. Thanks.
    • When selecting which side to unload. Select based on your Diagnosis. If you have Medial OA, select Medial when you place your order.
  • David at 5/7/2016 10:46 AM
    • Hx grade 3 lateral and grade 2 medial jointarthritis left knee. Recent meniscal surgery both lateral and medial. Lateral tear was complex. Need brace to take stress off knee joint- more lateral since grade 3 and provide ligament protection from previous acl incomplete tear AND further cartilage damage. Age 58. Thanks
    • Based on your diagnosis, There are a couple of options to choose from . A hinged knee brace will provide you with general support of the knee joint but it will no unload either side of the knee. The Don Joy Playmaker II would be a good choice since it will also provide ACL support. We also have braces specifically for arthritis called unloading OA Braces. These brace can unload either the medial or lateral side of the knee to provide decreases in apin on that side of the knee. You can only unload one side not both, so if you wanted to get one of these types of braces, you would only be able to unload one side. The OA Adjuster 3 would be the appropriate brace for severe OA.

    • I had a fractured femur in the knee joint the oats procedure is what was used to repair it. I now need a unloader brace at times of high activity as from the injury my alliginment is poor it feels sometimes like bone on bone and the unloader removes the contact from the inside of my knee would this be a good brace or what would you suggest. I currently have a custom Townsend brace and sleeve.
    • The OA Nano is best for moderate OA and a highly active person. The frame is made of magnesium so it would not be for contact sports and it will unload one compartment of the knee.
  • Kim C. at 3/9/2016 6:11 AM
    • December 2008, I had the first of two different trauma injuries to the right knee. Although one year apart from each other, these accidents resulted in two full knee reconstruction surgeries. Since then I've had orthovisc injections, I've worn a knee brace, have spent thousands on P/T and pain meds - and as I get older (and heavier) I'm finding it more important to exercise and I'm less and less able to do so. After 7 years of "doctoring" this knee, I went to a new orthopedic doctor who suggested an "unloader" brace. Here is the rub... I have pain on both sides of the knee (medial and lateral), as well as patella pain which is probably the most excruciating of all. Since having the first surgery, I've also developed arthritis laterally.

      I am 47, female, 5'6" tall and currently weigh 185 lbs. - I need to get active again so that I can reduce my weight with a goal of 145 lbs.

      My current brace is a don joy for ACL injuries and I find I can only wear it over top of leggings with a tunic top, or under a dress. Unfortunately, I find that wearing my brace all day, every day is the only thing that helps...yet I still have pain. (likely because it is not an offloader brace) My doctors office recommended the Nano.

      1. Will it fit under women's jeans?
      2. I have large calfs, and atrophy'd quads - if this works (and I hope it does) ideally the calf will get smaller and the quad will get bigger. How much adjustment will the adjusting straps give as I go through weight loss?
      3. Do you think the Nano is the best choice for me? (women specific frame?)

      Thanks for any help!!
    • The Nano is considered a "off the shelf" brace so if is measurmed with three measurments and has a range in each size. So a brace at one size will only fit a certain range then will need to go to another size. A Custom OA Defiance is made specifically for your knee and if you loose weight the brace can be re-made for a smaller charger than purchasing a new brace. To do an unloading brace we would need to know which compartment to unload either the mediual or lateral to get that benefit. If you have severe OA in both compartments the only brace that will be able to offloead either side (only one side at a time) will be the Defiance.

    • There should be a phone number on your medicare card that you can call for that information
  • Timothy at 12/23/2015 2:01 PM
    • My measurements for a Nano or Adjuster3 knee brace are: Thigh=16";
      Knee center=16"; Calf=13". What size knee brace should I order? I have bone on bone osteoarthritis and I am considered sedentary.
    • Based on these measurements you will not fit into a double hinged knee brace because your knee is a size large and the thigh and calf are small. We do have a single hinged OA brace called the OA Assist that would work better for you. https://www.betterbraces.com/oa-assist-osteoarthritis-knee-brace This brace will allow you to get a small and the knee center measurement will not matter

    • I have had a Donjoy OA NANO brace since Nov 2013. I run 3 times a week with the brace and it has served me well. However, the material that pads the inner frame of the brace is detoriating. Can the padding be replaced and if so do you provide such a service.
    • Michael
      You can order the liners for the OA Nano by calling DJO Global direct at 800-336-6569. You will need to know what size brace you have and what compartment the brace is for.

    • I'm looking at getting a knee brace, i have mild oa in my right knee and the knee cap is beibg pulled to the outside of the leg. Do i need a prescription to get one and go thru my insurance
    • Hi Christina,

      Better Braces does not deal with insurance or bill them directly. Your specific insurance may have regulations on getting a reimbursement, but if you would like to pay out of pocket, you do not need a prescription to place the order through Better Braces.

  • Carrie at 4/24/2015 12:21 PM
    • another question I have - I was told this brace was shorter and does not go down the calf as much as other braces. is that true and could you please give me the how many inches below the knee it goes? Also, I has another email which I am waiting for reply regarding the sizing. I already have the Reaction Web and also the microtek knee brace- both in size small, however, I really measure at the very end of the size small with my thigh. I have tried both these braces in a small instead and they were really too big and yet the XS did not have much velcro room to close the brace tightly, especially over my knee. The mediums had too much and no place to attach the velcro to. What do you suggest for the Nano? Is there more room to attach the velcro further if I get a small - or if I get an XS, is the velcro a little longer than the other two braces I already have? I will definitely need to wear this brace under my jeans as I do with the XS microtek knee brace with hinges since I can't wear either of these under the pants
    • Carrie
      The total length of the brace is 14.5 " , the bottom cuff is 6.5" below the knee
  • Michelle at 3/23/2015 6:30 AM
    • I need a right lateral knee replacement but due to polio they don't want to go ahead with that. My knee angles medially so I thought it would be best to have the nano knee brace with the pressure coming from the medial side to stop the bones rubbing on the lateral side. Do I order a medial or lateral??? My physio also agreed with me but we are not sure which one I should order to accomplish this. Thanks
    • Michelle
      OUr OA braces push the knee towards the opposite side to unload that same opposite side. You were correct you will want to go with the lateral brace and you will adjust from the medial side to push the knee towards the outside.
  • Greg at 2/28/2015 5:58 AM
    • How long should the OA Nano Brace Last? I have worn My Brace Daily for a little 13 Months, and the Metal Frame has Broken. The Frame that Cover the upper Thigh has Fatigue Cracked and it totally separated. Would l=this be covered under Warranty? I like the Brace, and it really helps to reduce the swelling and Inflammation.
    • Greg
      Although the OA Nano has a one year warranty on the frame and hinges the frame should not have broken after such a short period of time. Please call me at product support 888-405-3251 so I can arrange a replacement. And get your brace sent in to us.
  • Annie O'Shea at 2/21/2015 2:11 PM
    • I bought a DonJoy OA Reaction Web Knee and it has served me well, except that the velcro wore out and you replaced it. My condition has worsened dramatically and the brace isn't effective anymore as far as pain control...still feels supportive, though. I was never sure if the offloader idea really worked. A rep came by to make sure I was wearing it properly. How do you know if offloading is working? Less pain?
      Anyway, I can't get a knee replacement for several months and I was wondering if a stronger brace might help until then. My main activities where I used the brace were low impact aerobic dance and brisk 3-5 mile walking. I have had to stop since even with the brace I have terrible pain afterwards.
      THX Annie
    • Annie
      The OA Reaction Web knee Brace is for someone with mild OA, so if you need a knee replacement then your knee is most likely more severe than mild. The offloading should help decrease the pain in that compartment. We do have other braces that will offer more off loading. The OA Nano is for mild to moderate OA and the OA Adjuster 3 is for severe OA. The Nanao is a lighter brace, only 14 oz and the Adjuster 3 is 23 oz. https://www.betterbraces.com/donjoy-oa-adjuster-3-knee-brace
  • wyyuan at 2/10/2015 5:17 PM
    • I used to be a very active sport player playing soccer, tennis etc and 8 month ago fell in love with badminton, then my OA knee is getting worse. May this brace help if I wear it while playing badminton?
    • Wyyuan
      Yes the OA Nano is for very activie people and can be used duting actvities. The brace will unload either the medial or lateral side of your knee while wearing it.
  • MRI gal at 1/15/2015 12:57 AM
    • I am a MRI Technologist. Can the uploading brace be worn while working in the MRI suite? I need to find out if all of the materials are MRI safe. This in reference to working in MRI, not having a MRI.

    • There is metal in the brace so you will have to go by your protocols for that specific MRI machine that you have in place at your facility
  • Illini-Chris at 1/1/2015 10:47 AM
    • I am (had been) a marathoner and long distance triathlete. I suffered a torn medial meniscus in right knee and previously had experienced some off-and-on mild knee discomfort. I had knee surgery to trim both the medial and lateral menisci. Unfortunately, the surgeon also felt the need to clean out the arthritis in the knee. There was one very small area of bone-on-bone (~10 mm.) Now the load transfer thru my knee is completely different, and I constantly experience discomfort and stiffness at the front of the knee, even in the absence of physical activity.

      I have a leg length difference with the right leg being about 1/2" shorter, which likely led to the more extensive damage in the right knee over the years. A recent MRI showed the following in the Bone Structures: "The patient has mild medial knee compartment joint space flattening. There is also mild flattening laterally. Marrow edema is present in the posteromedial aspect of the lateral tibia plateau I do not see a fracture line. There is also subtle marrow edema in the medial femoral Cordele as part of the medial knee compartment. There is moderate cartilage loss on both sides of the medial knee compartment less pronounced laterally."

      I do not plan to run any more marathons, but I want to be able to walk vigorously and maybe run a few miles on hard-pack, even surfaces a few times a week (or use elliptical or tread-mill.) I also want to be able to ride my bike long distances. What do you suggest to partially redistribute load thru brace to relieve pressure on knee, reducing the pain in front and preventing further damage? Damage is bilateral so I do not want to redistribute load laterally.

      Please be specific in your brace recommendations because there are a lot of options. Thanks.
    • It sounded like most of the damage is on the medial side of your knee so i would reccommend a medial unloading brace, most likley the OA nano or the OA Full Force Knee Brace. The Nano is lighter 14 oz compared to the Full Force with is 20 oz. They are both for moderate OA. But if you do not want to distribute the weight laterally the only other option is a hinged knee brace such as the Deluxe Hinged Knee Brace. This brace does not unload either compartment but will give general knee support. https://www.betterbraces.com/donjoy-drytex-neoprene-deluxe-hinged-knee-wraparound-sleeve https://www.betterbraces.com/oa-fullforce-knee-brace https://www.betterbraces.com/donjoy-oa-nano-knee-brace

  • Monique at 11/12/2014 7:55 AM
    • I am trying to figure out which OA brace would be right for me. I have been looking at the OA Nano and the OA Adjuster. I have been diagnosed with mild degenerative changes of the medial meniscus (right knee) and I also have a mild case of genu valgum (knock knees). I'm looking for something that I can wear everyday. I do go to the gym a couple of times a week, but work a sedentary job. I am also trying to figure out what size would be best (knee center- 14.5, thigh - 18, calf - 15/ I'm a 5'5" female). Also, I want to verify that i would gat a brace for right medial. Any information would be greatly appreciated.
    • Monique
      You need to decide what you are going to get the brace for. Do you want to get something to unload the medial meniscus? Then a medial unloader is what you want. If you want something to help the genu valgum, then you would get the lateral unloader, but that would push on the medial sid eo of your knee. The OA Nano is for mild OA so that would be a better choice than the Adjuster. You would want to wear the medium size
  • Jonathan at 10/24/2014 8:48 PM
    • I have a small articular cartilage defect/tear near the lateral femoral condyle. Is this brace suitable?
    • Jonathan
      Yes the OA Nano would be a brace that you can use to unload that lateral side of your knee. Make sure you choose lateral compartment when ordering
  • Doug Nguyen at 10/10/2014 11:37 AM
    • My left knee:
      a) Mild grade 4 patellofemoral chondromalacia
      b) Minimal medial miniscus degeneration, no visible meniscus tear
      Right knee:
      a) Grade 3 patellofemoral chondromalacia
      b) Proximal medial collateral ligament carring and mild degeneration
      c) elangated flat mediat popliteal cyst
      d) small joint effusion

      question: 1) can I play tennis freely with these braces? if so what type?
      2) will I still feel some pain while playing?
      3) will this restrict any moving, turning while playing tennis?

    • Doug
      Wit Chrondromalacia in both of your knees the Reaction Web Knee Brace may be the best knee brace to help reduce pain associated with the chodromalacia. The Reaction absorbs force and dispearses it into the webing of the brace to reduce anterior knee pain. The Braces are low profile so can be worn while exercising

    • It has a magnesium frame but there is some metal in the hinges so it might set it off
  • Dorothy at 8/7/2014 6:26 AM
    • What is the best way to clean the straps and liners of the OA Nano brace -- can they be put in a washing machine?
    • Hand washing is the best and air dry. I would suggest washing the entire brace instead of taking the pads and straps off so you don't have to figure out how to put everything back together
  • Michael Valentine at 4/25/2014 8:09 AM
    • My right knee was diagnosed with Stage 4 Arthritis with OA in the medial are. I'm currently using the OA Everyday brace and was looking for something with a little more support when I'm more active, but still in the same size weight as the Everyday. I also took my measurements which fall into several categories, Thigh-22", Knee-17", Calf-15". Which OA brace would offer some more support, still fit under most clothing and what size would you recommend?
    • Thank you for your question. The OA Adjuster would be a good brace for an active person. It is a bit lighter than the OA everyday and very comfortable. A large would be an appropriate size for you.
  • Kim at 3/4/2014 8:34 AM
    • Thanks for responding to my first question - to follow up... You recommended the OA Adjuster - which one them... the OAAdjuster 3 for 679.00 or the OAAdjuster Osteoarthritis brace for 649??
      Thanks for clarifying!
    • Thank you again for your question. The OA Adjuster and the OA Adjuster 3 are going to be very similar. The Adjuster 3 will be slightly lighter. The upright with the adjustable hinge on the OA Adjuster 3 will be made of magnesium as opposed to Aircraft Grade Aluminum. Both are going to be recommended for active life styles and moderate to severe OA. The Adjuster will be more rigid and slightly heavier, it would be suggested for larger people, or people who may be in activities that involve outside contact (example: construction workers). Please let us know if you have any further questions.
  • Kim at 3/3/2014 5:19 PM
    • Hi- I am curious about the right brace for me. I suffer from OA and have been diagnosed with a media meniscal tear as well as grade 3-4 chondrosis in the medial joint compartment. I am on my feet all day as a teacher and am looking for support in every day activities as well as moderate exercise and backpacking. Wondering which would be best, the nano, the OA Adjuster or e everyday. Thanks for your suggestions!
    • Thank you for your question. The OA Nano is a brace more commonly used for everyday activities as well as the OA Everyday. A more appropriate brace for you would be the OA Adjuster. This brace is recommended for active people with moderate to severe OA. Please let us know if you have any further questions.

      I am very small (5'1") and have very thin legs. 14, 14 and 10.75. I have only worn my new brace twice, and each time it has slipped down as I walk - a horrid feeling! Can you please give me some advice as to how I can stop it slipping down?
      Yours gratefully,

    • I have been diagnosed by my orthopaedic surgeon her in Valencia Spain as suffering from advanced chondropathy in the internal femorotibial compartment of my left knee, with small subchondral lesion. Sublaxation of the internal meniscus, presenting important altertion with small extension to the lower articular surface duto degenerative tear (in both meniscus. Chronic lesion of the collateral medial ligament. Articular hemorhaging, Baker quist. I will be undergiong treatment with plasma rich in growth factors, a treatment pionered by Dr. Mikel Sanchez successfully with athletes, e.g. Rafa Nadal. I am 65 years old and normally have played tennis 4-5 days a week and also ski when the season permits. I want to continue playing tennis. My question is whether tieh OA Nano brace is the most indicated for my condition, to alleviate pain, and permit the best possible rercovery. Thank you for any guidance you might be able to provide. Daniel Soltice
    • The OA Adjuster 3 would be a better choice, if you want to wear it to ski. The Nano is light wieght but not as durable as the OA Adjuster 3. The OA Adjuster 3 wieghs aprrox 20 oz. You would want to order it for the medial compartment. Here is the link
  • K Srinivas at 1/29/2014 3:03 AM
    • I have early stages of OA affecting my both knees. I am using Don Joy Medial nano unloaders. My question is it it ok to use the treadmill with these unloaders or is there a danger of further deterioration.
    • Hi,

      The DonJoy OA Nano will still give the support needed for mild activity. This includes light work on the treadmill. Any walking or light jogging is what these braces are designed to help with. If you were looking to do more intense style of training, it would be recommended to move up to a more rigid framed brace like the DonJoy OA Adjuster 3. The more rigid frame can just hold up better to the demands of high intensity activity. (https://www.betterbraces.com/donjoy-oa-adjuster-3-knee-brace)

      Have a good day!

    • I requested feedback yesterday but now realize that I made an error in supplying my measurements. Could you please re-evaluate using the following corrected information.

      Wish to purchase Don Joy OA nano Knee brace sizes are a little of with measure ment chart, as follows: thigh 20", Knee 17", calf 16", please advise best option.
    • Arthur
      The meausrements are between a Medium and a Larg. We need to acomidate the knee width so go with the large, you can bend in the frame a little if it is slightly too big, your cal f should be fine but you can do the same for that as well if there is a litte extra room

    • Hello,

      I recommend you re-measure. Your thigh is an XXL, knee is XL, and calf is a L. This would require a custom knee brace. Re-measure and see if you get the same measurements.

      Thanks for Contacting Donjoy

    • Hello Damon,

      Here is where your measurement fall.


      Looks like you may have some atrophy of your quadriceps muscle. I recommend the XXL, the thigh and calf bar are malleable, you can bend the thigh frame to accomodate the smaller size.

      Have a Great Day.

    • I have the DonJoy OA Nano Knee Brace which my doctor recommended I use after my second knee surgery this May. It does help a lot with my walking. I do want to know if the brace is water proof. I was reading all the information about the brace and it doesn't say if I can get the brace wet.

      Thank you
    • Hello Laurel,

      Yes, you can use the brace in water. We recommend you rinse the brace each time you exit the water.

      Thanks for contacting Donjoy.

    • Using OA NANO How to adjust the 1,2,3,4,5,velcro straps to prevent the hinge from slipping below the knee ?

    • Hello,

      Below you will find links to videos, click on ACL Fitting. This is not your Brace but it's the same application. Each Strap is labeled, in order of application.

    • I have had a lateral release and 3 scopes to remove loose cartilage, especially on the back of my knee cap. After the third scope which was 12/2012 my knee hasn't recovered as it has in the past. Pain across the front of the knee, the outside, and the inside of the back of the joint that the doctor tells me it is due to the swelling that occurs when I engage in physical activity. It also hyperextends and gives out on me from time to time, and is showing the beginning signs of OA. Which brace would you recommend for me? Thanks in advance.
    • Hello Matt,

      Do you have medial or lateral OA or Both? Find out from your Physician which meniscus is affected.

      An OA Brace is not recommended for someone who has Bilateral OA. It would cause more pain. Since, an OA brace shifts the weight from the affected side of the knee to the healthy side.

      If you are not a candidate for an OA Brace I recommend a Soft Hinged Brace or a Rigid knee Brace.

      See Below.

    • I have medial joint space narrowing. On my selection would I choose "medial"?


    • Hello, Steve -

      Yes, you would choose the option "medial" which will open up the medial portion of the joint.

      If you have further questions, please feel free to contact our product specialists at 888-405-3251.

      Thank you and have a wonderful day!

    • Hello,

      Yes all of our OA Braces provide off-loading to mechanically shift the painful joint load from the degenerative compartment to the healthy compartment.

      Have a Great Day.
