Most arthritis braces feature hard shell designs to offload the involved side of the arthritic knee joint. The Donjoy OA Reaction brace has a discreet form-fitting design that won't slip for greater comfort with daily activities.

Very well made and works well. The fit is OK, but could be better. There could be slightly more space between the side support piece and the patella hole. Also, the thigh strap isn't quite as tight as I'd like, but the knee and calf are good.

Helps with my arthritis
It's very easy to put it on and I don't have to adjust anything. If I did not wear this my knee would be aching every time I started to walk. Thank you for the fast delivery.
