A stabilizing knee hinge which can be utilized in conjunction with a brace for bracing or casting the human knee. The hinge simulates the movement of the human knee and can be utilized to restrict the range of motion of the knee to any desired range or to completely immobilize the knee joint. The hinge includes a femoral joint element which has two plates secured in a fixed parallel relationship. Two arcuate cam slots are formed through both plates. A pair of generally circular stop limit plates are rotatably mounted within the two femoral joint element plates and may be independently rotated to intersect the arcuate cam slots. A first stop limit plate rotates in one direction to set the stop limit for knee extension and the second stop limit plate rotates in the other direction to set the stop limit for knee flexion. A set screw is provided to fix the position of the stop limit plates as desired. The tibial joint element includes a second pair of plates which are secured in a fixed parallel relationship and which are disposed outside of the femoral joint element plates. A pair of pivot and bearing pins couple the tibial and femoral joint element plates through the arcuate cam slots in the femoral joint element plates. The tibial joint element is then free to rotate with respect to the femoral joint element in a composite arc defined by the arcuate cam slots and the position of the stop limit plates.
