ABSTRACT:
A knee support is provided for opposing excessive or abnormal strain or torque on the joint. The support has a pair of pivotally interconnected rigid braces one of which snugly embraces the front of the thigh just above the patella and the other of which snugly embraces the front of the shin just below the patella. The pivots are aligned approximately on the mean medial-lateral axis of flexion of the knee and at least the pivot on the lateral side has freedom of universal pivotal motion while that on the medial side has limited freedom of relative bodily displacement in the anterior-posterior direction. Both freedoms are of sufficient magnitude to accommodate the wearer's normal degree of tibial rotation during flexion and extension. Means are provided for locating each brace firmly on its respective component of the limb.
