- I ordered a medium/large brace but the sleeve is too large. When I looked at the replacement sleeves they come in both medium and large. Which is the size that comes with the medium/ large brace? Is it medium or large?
- The sleeve that comes with the Medium/Large Reaction is a Medium. If the Medium sleeve is too large, try ordering a small.

- Need a second under sleeve for my daughter's custom Force Point knee brace (lacrosse athlete, s/p ACL repair). She likes what came with the brace but it's getting stretched out after almost a year of frequent use. Is this the correct choice? Thank you!

- I received my Donjoy brace from my doctor who measured my calf, knee and thigh before ordering the brace and it relieved the awful pain in my knee. But I get blisters from where it is connected. My question is should I have had a sleeve with the brace?
- Alfred
A undersleeve could help with any friction the brace is creating on your skin.

- What options are there if you have a silicone allergy? So far we have had to wear the sleeve inside out. This works but obviously not as good as with the "stay put" dots of silicone.
- Laura
If the sleeve is causing irritation we should be able to sen our Lycra undersleeve to you instead. Just call BetterBraces if you purchased from there, or call customer care at 800-336-6569

- I have a Bledsoe knee brace that slides down while using, will the reaction knee sleeve prevent this? I need more friction to prevent the sliding.
- Peter
If you want an undersleeve to prevent your Bledsoe brace from slipping 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 sleeve for the Reaction might work under the other braces to keep the heat rash down

- Are you able to ship the Donjoy Reaction undersleeve to the UK? I already have the brace, which is excellent, but my sleeve is becoming threadbare.
If you can send it, what shipping charge would I incur if I ordered two?

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

Thank you for contacting product support. The Reaction Knee Brace is for those who suffer from anterior knee pain caused by patellofemoral dysfunction, problems associated with the kneecap and mild arthritis. If you need medial and lateral support you need to stick with a hinged knee support.

Use of sleeve and brace before surgery and sleeve alone after
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.This brace is great!
I just got my brace yesterday and I love it!! It helps support my knee so that I have no pain or swelling. It stays in place and doesn't pinch my leg. I like it better then the copper brace that I have and I wish I would have ordered two of them.Slides Down
Size runs big and keeps sliding down bringing the brace with itI NEVER want to experience a meniscus tear again -- but if I do, I know who to call.
This sleeve helps make my knee much more comfortable. I'm a large gal and needed a 3-X at the start. I have since orders the next two smaller sizes as the swelling in the knee and leg went down. This sleeve stays in place. Best of all, on the miserably hot and humid days we've been experiencing here in Kentucky, the sleeve is breathable and comfortable even on long days and through extended hours of wear.Can't put my brace on without it!!
I have been wearing a knee brace for 23 years. This is the ONLY sleeve I would ever wear or recommend. Its the BEST!! Thanks, God Bless......Pros: The Best! try it and see for yourself.Cons: I only found them a few years ago.Share Your Usage: Recovering from Injury, Daily Use, Chronic Instability
I would purchase this or something comparable by Better Braces.
Purchased the Donjoy Reaction Knee Undersleeve for my Husband who has knee problems he travels a lot prefers this brace because it breathes and it is long enough so that if he is able to extend the knee the sleeve is not cutting off his circulation.Top notch!!
This goes perfectly with my brace. Regretfully since I managed to fracture the distal tip of my fibula I cannot wear the brace right now but I do wear the sleeve for compression and have found that it helps tremendously.Not as pictured
I bought this to wear under my shorter knee brace, but the one pictured and the one I got were very different. What I got was a plain black, thin cheaply made sleeve. The hem was very cheaply done and the material was not good quality. I sent this back.Cons: Not as pictured.Share Your Usage: Chronic Instability

These braces saved my life :)
These braces saved my life :) I was using ace bandages that kept falling and constantly needed to be tightened. My dr's office recommended this brace to me. I tried it and loved it, then bought 3 more as back up :) I can walk up the stairs now and can even ride my bike in them.You may also like
