Clinical and Arthroscopic Evaluation of Posterior Cruciate Ligament and Posterolateral Corner Injuries of the Knee

Posterior cruciate ligament (PCL) and posterolateral corner (PLC) knee injuries are relatively rare but can lead to significant instability, dysfunction, and chronic knee pathologies. Recent trends in the literature suggest that the best clinical outcomes are obtained through the early identification and timely management of PCL and PLC injuries. Appropriate use of physical examination tests and imaging studies is a crucial part of the initial assessment, allowing identification of all associated injuries and accurate preoperative planning. In this article, we present an evidence-based approach for the assessment of PCL and PLC injuries by focusing on the physical examination, relevant imaging studies, and diagnostic arthroscopy.
