Abstract

The structures of the posterolateral corner (PLC) work together as a single unit to provide both static and dynamic functions to the knee. Multiple techniques have been described for PLC reconstruction, however most of these techniques re-establish the static function of the PLC without addressing dynamic components. The popliteus muscle serves an important role in providing dynamic stability to the PLC, but this function is often not restored in reconstruction techniques. We describe a novel technique for PLC reconstruction that includes popliteus repair, and review the functional anatomy and biomechanics of the PLC. We also confirm the dynamic stabilizing role of the popliteus muscle through a biomechanical analysis of four cadavers.
