Reconstruction of the Posterolateral Corner of the Knee

Abstract

ABSTRACT The following article outlines the historical perspective, indications, and operative technique for reconstruction of the posterolateral corner knee. We prefer a fibular-based reconstruction utilizing a semitendinosus autograft to reconstruct the stabilizing structures of the posterolateral corner. Although the anatomy of the posterolateral corner is complex, we believe that reconstituting the lateral collateral ligament and the popliteus-popliteofibular complex effectively restores the varus and rotational stability afforded by the posterolateral corner. Advantages to this technique include the limited dissection and decreased surgical time compared to other procedures. In addition, the procedure does not significantly disrupt the anatomy of the posterolateral corner, and hence can be used to augment a primary repair of the posterolateral structures.
