Transosseous reconstruction of the posterior cruciate ligament: Single-and double-tunnel techniques

Posterior cruciate ligament (PCL) injuries represent between 3% and 37% of all knee ligament injuries reported in the literature. The wide range exists because of the various mechanisms of injury seen by the investigators. The traditional reconstruction of the PCL has been a single-bundle technique. Attention has been focused on reconstruction of the larger and stronger anterolateral bundle. Other investigators have explored the concept of an isometric 1-bundle reconstruction. Recent biomechanical data have suggested that a double-bundle technique, including the additional reconstruction of the posteromedial bundle of the PCL, can better reproduce physiologic posterior tibial translation throughout the knee range of motion. We will discuss the techniques of both single-and double-tunnel reconstruction of the PCL.
