DonJoy Reaction Knee Undersleeve reviews

Before having knee surgery for a knee replacement my doctor ordered your brace and sleeve for me. The combination along with medication helped me greatly with the terrible pain I suffered. After the surgery I recently started using the sleeve alone because of pain and swelling. It has given me excellent results with pain and the swelling. I highly recommend your products. - Shirl

    • I have a Bledsoe knee brace that sides down while using, will the reaction under sleeve prevent this? I need more friction to prevent the sliding.
    • Peter
      If you want an undersleeve to preven your Bledsoe brace from slippig i would suggest the neoprene undersleeve.

    • My Dr. put me in the DONJOY Drytex™ Hinged Knee Brace about 2 weeks ago. Been doing well till it hit over 100 degrees recently. Now I have a bad heat rash. I also wear braces on both feet/legs and the heat rash is there also. What do you recommend to wear under the the foot/leg & knee brace to keep down the heat rash? I was looking at the DonJoy Reaction Knee Undersleeve and was wondering if this would help?
    • Van
      The undersleeve for the Reaction might work under the other braces to keep the heat rash down

    • I was wondering what is the length of the Don Joy reaction under sleeve? I currently have one that is 15.5' and am looking for something close.
    • Un-stretched it is about 13 inches

    • Are you able to ship the Donjoy Reaction undersleeve to the UK? I already have the brace, which is excellent, but my undersleeve is becoming threadbare.

      If you can send it, what shipping charge would I incur if I ordered two?

    • Hello,

      We do not ship outside the U.S. Please contact your local representative for purchasing the replacement undersleeve.

      Thanks for Contacting Donjoy.

    • I was issued a DonJoy Knee Brace back in 2001 or 2002 to better support my right knee that was made for stable with screws. I found that knee brace to be cumbersome. Will this knee brace work for my knee?

      Thank you
    • Kelile
      Thank you for contacting product support. The Reaction Knee Brace is for those who suffer from anterior knee pain caused by patello femoral dysfunction. Problems assicaited with the kneecap and mild arthritis. If you need medial and lateral support you need to stick with a hinged knee support.
