• 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!
• We have the Cotton/Lycra Undersleeve for the rigid knee braces. https://www.betterbraces.com/knee-brace-undersleeve-cotton-lycra

• 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 other donjoy knee braces can I wear the DonJoy Reaction Knee Undersleeve with?
• You can wear that under sleeve with any brace although it is only 13 inches in leangth

• 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

• 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 sleeve is becoming threadbare.
  
  If you can send it, what shipping charge would I incur if I ordered two?
  
  Thanks
• Hello,
  
  Unfortunately, we do not ship outside the U.S. Please contact your local representative for purchasing the replacement sleeve.

• 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

• Kelile
  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.
Roberta at 6/26/2013 11:43 AM
• What type of brace or sleeve is best for a cyst behind the knee?
• Hello Roberta,
  
  I recommend a Knee Sleeve for compression. Take a look at your options below.
