Dual Postero-Medial Portal Technique for Posterior Cruciate Ligament Tibial Avulsion Fracture Fixations.

Abstract

The posterior cruciate ligament surgery invariably demands adequate posterior compartment visualisation and instrumentation. The addition of posteromedial (PM) portal during posterior cruciate ligament (PCL) surgeries remains essential. The further addition of one more proximal posteromedial (PM) portal further enhances the instrumentation including suture passage in the substance of PCL or screws insertion and more so obviates the need for trans-septal and posterolateral (PL) portals. This additional PM portal is created in the safe zone under direct visualisation utilising outside-in technique and is spaced to prevent crowding of instrument with arthroscope. The proximal higher PM portal serves as instrument portal and provides optimal trajectory for even arthroscopic screw fixation of PCL avulsion fractures.
