Clinically proven to provide pain relief.* This single-upright OA brace provides the greatest amount of OA correction on the market. The unique design of the hinge allows for 36° of brace angulation. This allows the brace to unload knee joints that have excessive tissue. It can be made to unload the medial or lateral compartment of the knee. *Komistek, Richard D.
