ABSTRACT:
A knee brace for control of ligament instability in all planes having thigh and shin cuffs, a polycentric hinge on the lateral side of the knee, and a pivoting articulation plate on the medial side of the knee. The cuffs are attached to the leg by non-stretchable straps and provide anterior-posterior stability. The medial pivot plate stabilizes the brace on the medial side of the knee and in combination with the lateral hinge and a lateral plate provides medial-lateral stability. In another embodiment the cuff is replaced by thigh plates with adjustable connecting means to accommodate different sized thighs. The thigh plates, medial plate and shin cuff are shaped to permit interchangeable use on left and right knee braces. Adjustable front and rear straps connect the medial pivot plate and shin cuff for providing ligament stability and adjustability as to various knee widths.
