We mechanically shift weight away From the damaged part of the knee to help address four common relief Points for those suffering from OA*

Every DonJoy® OA knee brace can off-load either the medial or lateral compartment and incorporate load adjustment mechanisms that allow patients to fine tune their brace to meet their daily needs.


Pain caused from OA of the knee can create barriers to motion both psychological and physical. Addressing immediate pain issues is essential to getting active.


If the body’s alignment is not correct, it can create wear on joints that can cause pain. Incorrect alignment can be natural, can come from an injury or can be the result of the body compensating for pain.


As knee pain increases, the body compensates to avoid the pain. Quadriceps stop firing and more pressure is put on joints exacerbating the situation. Maintaining strength in key muscle groups is critical to reversing the path of degeneration and getting back in motion.


Instability can be real, whether from injury or from OA, and it can also be perceived, as when sharp pain creates the impression of instability. Real or perceived, instability can be a barrier to motion.
