Arthroscopic posterior cruciate ligament reconstruction using the posterior trans-septal portal.

We describe an arthroscopic technique for the reconstruction of the posterior cruciate ligament (PCL), while preserving the remnant bundle of the original PCL and meniscofemoral ligament, using the posterior trans-septal portal. The posterior trans-septal portal provides an excellent visualization of the PCL tibial attachment and an easy access to the tibial tunnel without injuring any neurovascular structure. The remnant bundle of the original PCL and meniscofemoral ligament, which significantly contributes to the posterior stability of the knee joint, are preserved to be healed with a graft and subsequently form an integrated structure. We report a new arthroscopic technique for an effective reconstruction of the PCL, using the posterior trans-septal portal.
