What is the Donjoy OA Reaction Web Knee Brace?

Donjoy OA Reaction Web Knee Brace is an entry level knee brace for those suffering from the early stages of osteoarthritis (OA) and chronic knee pain. Designed to off-set pressure and support the patella, the brace uses medical grade silicon which has been anatomically designed to extend and retract with various leg movements.

Don't let OA knee pain slow you down

As of this year, 8.5 million people are afflicted with OA, and a staggering 175 million people are affected by it worldwide. OA is a degenerative disorder in the knee that affects the cartilage and can be brought on by a number of factors ranging from post-operative stress, sporting trauma, or even old age. Cartilage is slowly worn away, causing movements to become painful and joints to be distorted as the body attempts to repair itself.

While there is no cure for it as of yet, knee braces can aid in slowing the degeneration and provide suitable pain relief for OA sufferers.

How does it work?

Donjoy OA Reaction Knee Brace uses a number of techniques to relieve OA pain. The most notable is the patented open web design, which features a network of durable, high grade silicon that wraps around the knee to provide appropriate shock absorption and support. The silicon absorbs and releases kinetic energy, allowing the wearer to regain confidence in their movements and stay active.

The brace also uses two silicone condyle pads that support the knee on either side. Non-slip and secure, the condyle pad uses a hexagonal design to create an air pocket which holds closely to the skin. These pads not only aid in pain relief, but also off-load any extra pressure being placed on the affected compartment.

Lightweight, breathable, and discreet, the Donjoy OA Reaction Knee Brace comes with a fitted undersleeve to gently compress the skin to increase blood flow and promote recovery. Combined with contoured back pad, straps, and moisture wicking material, it becomes clear that this knee brace has been designed with maximum comfort in mind.


  • Breathable and lightweight open web design
  • Silicone condyle pad to provide gentle off load
  • Adjustable aluminium uptight to increase off-load
  • Easy to wear wraparound design
  • Discreet design that can be comfortably worn under clothes

“Good but rather restrictive for sport”

Reviewed by sahara

I have unstable and hypermobile joints and need knee supports to use on the treadmill, bike and walking. The support felt very comfortable and made my knee feel instantly secure and 'safe' but I couldn't imagine trying to jog in it. I could, at a push, probably walk in it, but even then I think it would restrict movement a bit too much. I think this would be excellent for everyday walking around to help with knee pain, but not for exercising in. At least, not for me anyhow. I have returned it and ordered two of the Ultimate Runners Knee Straps, to see if they do the trick.
