S/P Lateral Posterior Lateral Corner Reconstruction
The posterolateral corner (PLC) of the knee is a complex area of the knee formed by the interaction of multiple structures. Injuries to the posterolateral corner can be debilitating to patients and require prompt recognition and treatment to avoid long term consequences. Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). The structures considered for potential reconstruction are the fibular collateral ligament, popliteus tendon, and popliteofemoral ligament. The FCL and/or popliteus tendon are only considered for acute repair when they are avulsed off bone and can be reattached anatomically with the knee in extension. The PFL can be repaired when it is torn directly off of the fibular head and the popliteus is still intact.
