ABSTRACT:
A knee brace (400) includes a first hinge portion (408) having a face (426) comprising a plurality of circumferentially equally spaced teeth (428). An adjusting disc (440) has a first circular face (442) comprising teeth (448) which mesh with the teeth (428) of the first hinge portion (408) to lock the component parts of the knee brace (400) in any desired angular relationship. A second hinge portion (418) has a face (436) comprising a plurality of slots (438a, 438b, 438c and 438d). The adjusting disc (440) has a second circular face (444) comprising a tooth (450) which is selectively engageable with one of the slots (438a, 438b, 438c or 438d) of the second hinge portion (418) to regulate angular movement between the component parts of the knee brace (400). A torsion spring (462) has projections (468, 470) which are selectively positionable in apertures (422, 432) of the first and second hinge portions (408, 418) to apply a predetermined torque to the component parts of the knee brace (400).
