Abstract

A casting method for a brace having corrective forces is disclosed. The foot is externally rotated during casting and corrective forces are applied at the lateral knee and anteromedial ankle. With the knee flexed at between about 70° to 90°, the cast is fully extended, which places the knee in a position which will reduce the pressures on the medial knee. This is the position desired during the casting process with the knee flexed and then held while extending the knee. The result is control of the posterior lateral rotation, therefore controlling the posterior subluxation of the tibial plateau to achieve the motion and alignment that the screw home motion produces.
