ABSTRACT:
A spiral-shaped knee brace which includes spaced, laterally extending rigid members which overlie and support the lateral and medial portions of the knee joint, a section which interconnects the rigid members and spans the popiliteal region of the knee, a band that traverses the front of the upper thigh and is joined to one of the rigid members, a band that crosses the front of the lower tibia and is secured to the other rigid member and means for releasably securing the brace in its operative orientation about the knee. Valgus and varus stress and lateral and medial bending are blocked but the brace allows a selective amount of flexion of the knee and the rotation or locking home movement of the knee is not disrupted. Flexible and rigid embodiments of the brace are disclosed.
