How Does the Donjoy OA Reaction Knee Brace Work?

The Donjoy OA Reaction Web Brace uses patented silicone ‘web’ technology that extends and retracts as your leg moves. This helps absorb and release kinetic energy to reduce shock, anterior knee pain and stress on the knee.

Designed with a single malleable aluminium upright that’s built with 6° of valgus correction, the Left Medial/Right Lateral Support enables you to adjust how and where the support offloads pressure.

How Does Offloading Work?

Offloading means that the pressure is moved from one side of your knee to the other. As arthritis is caused when two bones rub on one another, by relieving these bones of pressure, it means that you don’t feel the pain associated with OA.

How Long Do I Have to Wear the OA Web Brace For?

We do recommend that you build up the amount of time that you spend wearing the brace. OA braces are designed to realign your leg, so taking your time and getting accustomed to thee brace is a good idea.

How Comfortable Is the Donjoy Reaction Web Brace?

The Donjoy Reaction OA Web Brace features a unique, silicone web that is lightweight and discreet. It fits over the kneecap, bending in such a way that it doesn’t cause your patella stress. This means that the brace is extremely comfortable during use.

Is This Support Suitable for Watersports?

This support can assist with the impacts and pain associated with water sports, but if it is used in salt water, it should be rinsed with clean water after each use. It should then be dried, as some components of the brace may wear over time if left waterlogged.
