Abstract: The invention pertains to a patellar stabilizing orthosis used in conjunction with rehabilitation programs involving all nonsurgical patella dislocations or mal-alignments including chondromalacia patellae, dislocation of the patella or subluxation of the patella. The orthosis is designed to achieve left or right lateral or left or right medial stability, and includes a U-shaped body member formed of nonelastic material wherein parallel legs extend from a base portion. A pad located adjacent the inner surface of the base portion is positioned laterally with respect to the patella and the legs are wrapped about the wearer's thigh and calf, and fastened in an overlapped manner. A pair of elastic straps affixed to the body base portion extend obliquely therefrom in a direction opposite to that of the legs and are affixed to the legs while under tension to produce the desired traction against the patella.

Abstract: The invention pertains to a knee cage for providing additional orthopedic support to the knee wherein a multicentric hinge is employed to permit natural knee flexure and high lateral support. A flexible cover of fabric having loops defined in the outer surface thereof is wrapped about the knee and held in an embracing manner by elastic straps. Hinge means each formed by a pair of hinge elements interconnected by multicentric pivot means are removably mounted upon lateral portions of the cover permitting the hinge means to be adjustably secured to the cover permitting optimum location thereon. Elongated elements of the hinge means are received within pockets having hooks defined thereon for cooperating with the cover loops to adjustably affix the hinge means to the cover.
