Current Arthroscopic Concepts in Repairing Posterior Cruciate Ligament Tibial-Sided Avulsions.

Posterior cruciate ligament (PCL) injuries are extremely rare and most commonly occur in the trauma setting. They can lead to instability, pain, diminished function, and eventual arthrosis. Several techniques of arthroscopic PCL repair for tibial-sided bony avulsions have been described in the literature; however, no single technique has emerged as the gold standard to predictably restore posterior knee stability, PCL function, and knee biomechanics. The authors believe that the best results will come from procedures that re-create the normal human anatomy and knee kinematics. In this article, 3 arthroscopic methods of PCL avulsion repairs performed at 2 academic institutions are analyzed. The techniques described here provide good options for the treatment of these injuries.
