Transmedial All-inside TriLink Posterior Cruciate Ligament Reconstruction

Abstract

Posterior cruciate ligament (PCL) injuries usually constitute part of a multiligament injury. Isolated PCL injuries account for only approximately 3% of all ligament injuries. No consensus on optimal surgical reconstruction exists. The PCL is a double-bundle structure that functions in an anisometric manner. Biomechanical studies have shown that re-creating the PCL femoral double-bundle configuration provides greater stability. We present a 3-socket approach for an anatomic “all-inside” double-bundle PCL reconstruction using our preferred option of a FiberTape (Arthrex, Naples, FL)–reinforced peroneus longus allograft fashioned to create a trifurcate graft: the TriLink technique. Cortical suspensory fixation devices are used, allowing differential tensioning of the anterolateral and posteromedial bundles. This enables more accurate replication of the native PCL and its biomechanical properties.
