Single-Bundle Anatomical Posterior Cruciate Ligament Reconstruction With Remnant Preservation

Abstract

Remnant always exists following injuries of the posterior cruciate ligament (PCL). To improve the clinical outcomes of PCL reconstruction, preservation of the remnant has long been a consideration. However, how to make the remnant-preservation technique simple and more effective is of concern. We describe a single-bundle anatomical PCL reconstruction technique with remnant preservation in which the posteromedial and posterolateral portals are used, the graft is placed at the lateral side of the remnant, and pulleys are used to facilitate graft passage at the 2 killer turns of the grafting routes. We consider introduction of this technique will provide reasonable choices in PCL reconstruction.

Is posterior knee arthroscopy using posterior portals necessary for orthopedic surgeons? The latest evidence on applications and techniques

“…As the tibial inlay technique fell out of favor, remnant-preserving PCL reconstruction has become popular ( 36 ) ( Fig. 6A ).…”

“…In addition to stabilizing the posterior horn of the lateral meniscus, the meniscofemoral ligaments also synergize with the PCL ( 39 ). By preserving them, the risk of graft failure can be reduced ( 36 ).…”

Quad Tendon Autograft for Posterior Cruciate Ligament Reconstruction Using Transseptal and Posteromedial Portals

“…The scar tissue of PCL is shaved, and the remnant of PCL is kept. 7 The lateral limit of the tibial socket is the popliteal muscle. We use a classic tibial drill guide inserted through the PM portal (PCL Toolbox; Arthrex, Naples, FL; Fig 5 ).…”
