Abstract
An osteoarthritic knee brace is provided having flexible upper and lower arm members rotatably connected to each other by a rotary hinge assembly. A selectively inflatable or deflatable fluid-containing pad is positionable between the hinge assembly and a side of the knee joint. In operation, the brace is mounted on the leg with the pad engaging both the hinge assembly and the side of the knee joint, the hinge assembly aligned with the knee joint, and the upper and lower arm members aligned with the upper and lower legs, respectively. The upper and lower arm members are stressed away from the knee joint, thereby applying a restoring force to the knee joint across the hinge assembly and the pad that effectively treats the osteoarthritic knee joint. The restoring force is adjustable by selective inflation or deflation of the pad.
