Injuries to the posterior cruciate ligament (PCL) and its methods of treatment have historically been surrounded by controversy in the orthopedic community. The infrequent occurrence of PCL injuries and PCL-based multiple ligament knee injuries has led to the limitations in clinical studies and a subsequent lag in basic science and clinical research when compared with other ligamentous injuries. In recent years, new studies have elucidated the biomechanical function and complex anatomy of the PCL leading to an increased interest in research, understanding, and treatment of these complex injuries. In addition to improved understanding of knee ligament structure and biomechanics, technical advancements in allograft tissue, surgical instrumentation, graft tensioning and fixation methods, improved surgical techniques, and postoperative rehabilitation methods have improved the results in PCL reconstruction and PCL-based multiple ligament knee surgical outcomes.
Contents of this dedicated PCL issue of Sports Medicine and Arthroscopy Review include anatomy and biomechanics, clinical evaluation, surgical techniques, rehabilitation, complications, and outcomes of treatment of PCL. As PCL injuries are commonly combined with other ligament injuries, the surgical techniques in this issue address single and double bundle PCL reconstruction, the tibial inlay technique, posterolateral, and posteromedial reconstruction. The surgical technique sections combined with the study on complications will provide our readers with an understanding of the complexity of this injury and its treatment, and promote safety of patient in this clinical area.
The purpose of this Sports Medicine and Arthroscopy Review Posterior Cruciate Ligament edition is to provide, experienced knee surgeons, general orthopedic surgeons, fellows, residents, medical students, and other health care professionals with an interest in the PCL, an overview for the evaluation and treatment of these complex injuries.
