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.
