Arthroscopic- Assisted Fibular-Based Dual Reconstruction With Popliteus Repair for Posterolateral Corner Injury.

The structures of the posterolateral corner (PLC) work cohesively to provide both static and dynamic knee stability. Injury to the PLC disrupts both the static and dynamic properties. Although multiple PLC reconstruction techniques have been described, most address only the static, and not dynamic, function of the PLC. The popliteus tendon provides dynamic stability to the PLC, but its specific function is not addressed in current techniques. We describe an arthroscopic-assisted fibular-based dual reconstruction with popliteus repair to restore static and dynamic stability of the PLC.
