ABSTRACT:
A knee brace is provided for supporting an injured interior cruciate ligament by using straps that produce a forced couple on the knee joint to keep the tibia properly behind the femur (anti-drawering) while allowing for adjustment of the amount of anti-drawering to fit the individual needs of the patient. The knee brace may utilize a quadricentric hinge that closely approximates the natural movement of the knee joint and allows for adjustment of the knee brace to account for the natural curvature of the individual patient's leg bones. The quadricentric hinge can include four gears. Typically, these gears may be two drive gears and two idler gears.
