Posterolateral corner reconstruction.

One should suspect a compromise of the lateral structures when presented with a posterior cruciate ligament (PCL) injury, especially if grade III laxity is present. In our experience, if a combined injury to the PCL and posterolateral corner is diagnosed, a combined PCL and posterolateral reconstruction is needed to restore stability. This article describes a posterolateral reconstruction procedure. This procedure, when used in combination with an intra-articular PCL reconstruction, restores rotary and posterior knee stability. This procedure uses allograft tissue and interference screw fixation, although autograft tissue may be used.
