DonJoy OA Reaction Web Knee reviews

Dpaws17
I have osteoarthritis and bone on bone I need a knee replacement but because I am so young my doctor wants me to put it off as long as I can. I have spent several hundred dollars in knee braces trying to find one that will help me. As soon as I put this brace on I knew it was the one for me. It gave me the support that I needed and was looking for. I am a letter carrier so I walk 8-10 miles a day this brace has helped a great deal thank you - Dpaws17

Sort by Descending
  • From Jerry at 10/12/14 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.
  • From Neoma at 10/22/14 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
  • From Susan at 10/25/14 9:32 PM
    • Do major insurance companies cover the OA Reaction Web Knee Brace?
    • Susan
      Insurance companies do usually cover the OA Reaction Web, but you may have to check with your insurance company to be sure
  • From Tia at 11/4/14 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.
  • From Marion Godwin at 11/16/14 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
  • From Dan at 11/17/14 8:32 AM
    • Can an flex spending account be used to purchase the reaction knee brace?
    • Dan
      As long as your insurance alows DME to be purchased with the card it will be fine on our end
  • From Jeff at 11/24/14 8:53 AM
    • 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
  • From steve at 12/3/14 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.
  • From Robert at 12/4/14 9:05 PM
    • I need this for my right knee, should i be buying the medial left or medial right? or lateral right or lateral left?
    • Robert
      It depends on the compartment that you want to unload. If you need to unload the medial compartment on the right knee then the Right medial /left lateral
  • From Chuck Dirienzo at 12/8/14 10:13 AM
    • If the pain is on the outside of my right knee, what option do I choose?
    • Medial left/ lateral right
  • From Melinda Whitman at 12/10/14 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.
  • From Stephen at 12/17/14 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
  • From Gary at 12/19/14 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.
  • From Thomas at 1/2/15 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.
  • From Nik at 1/6/15 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"
  • From Paul at 1/13/15 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
  • From Paul at 1/14/15 9:10 PM
    • My measurments are:

      thigh - 19.25"
      Knee - 15.25"
      calf - 16.5"

      Which is the best size for me for the OA Reaction Web Knee brace? The site says they run small and to go up a size if in between. I seem to be in between on some measurements but not on others. Is the medium the best size for me or the large?

      Thank you.

      Paul M
    • Paul
      The medium would be the size for you.
  • From jaclyn bader at 1/16/15 7:25 PM
    • 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 stabliTy..... I have pain on the inside of left knee so I need to know which one to order? Medial left? Thanks, jacki
    • Jacki
      The OA Reaction is for mild OA so it might not give you any relief if you have moderate to severe, 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 guarentee if it does not work for you.
