Anatomic reconstruction techniques for posterolateral corner injuries: Current concepts in management and rehabilitation

Background and Aims Posterolateral corner (PLC) injuries are complex knee injuries that compromise stability due to damage to critical stabilizing structures, requiring accurate diagnosis, effective surgical techniques, and structured rehabilitation for optimal outcomes. This review explores the anatomy, biomechanics, and diagnostic strategies for PLC injuries, emphasizing on LaPrade’s anatomical reconstruction technique and its role in restoring stability and function. Materials and Methods A comprehensive literature search was conducted across PubMed, Scopus, Embase and Web of Science for studies focusing on PLC anatomy, diagnostics, physical examination techniques, imaging, treatment approaches, and postoperative rehabilitation. Results The review highlights the roles of the fibular collateral ligament, popliteus tendon, and popliteofibular ligament in resisting varus forces and controlling knee rotation. Diagnostic approaches, including physical examinations, radiographs, and magnetic resonance imaging, are discussed to identify PLC injuries effectively. Surgical management focuses on anatomical reconstruction techniques, particularly LaPrade’s technique, to restore native biomechanical functions. Post-operative rehabilitation protocols are emphasized, with a structured approach to restoring stability, minimizing complications, and improving functional outcomes. Conclusion Combining anatomic reconstruction with a rigorous rehabilitation protocol has demonstrated favorable subjective and objective outcomes, providing an effective framework for managing PLC injuries and achieving long-term functional recovery.
