Simultaneous Anterior Cruciate Ligament, Posterior Cruciate Ligament, Posteromedial Corner, and Posterolateral Corner Reconstruction of the Knee.

Abstract

Concomitant injuries of the 4 groups of ligaments of the knee are a serious condition and challenge the orthopaedic surgeon when reconstruction of all ligaments is needed. Staged reconstruction can be chosen owing to the complexity of the combined procedures; however, simultaneous reconstruction is favored to facilitate recovery. We describe a simultaneous anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), posteromedial corner (PMC), and posterolateral corner (PLC) reconstruction technique, in which autografts are used and both cruciate ligaments are reconstructed in a single-bundle manner. We believe the introduction of this technique will familiarize surgeons with the principle of simultaneous 4-ligament reconstruction of the knee and the method of cruciate ligament balancing during bicruciate ligament reconstruction.
