Abstract

The purpose of our study was to assess effect of posteromedial corner(PMC) injury on clinical outcomes and second-look arthroscopic findings after posterior cruciate ligament(PCL) reconstruction using Achilles tendon allograft. A total of 51 patients who underwent arthroscopic PCL reconstruction for PCL rupture and second-look arthroscopy were retrospectively enrolled in our study from 2009 to 2019. The subjects were divided into two groups: PMC intact group included 31 patients; and PMC injured group included 18 patients. At least 1 years follow-up, clinical outcomes and arthroscopic findings including synovial coverage, tension were evaluated. Arthroscopic findings including the synovial coverages, tension showed significantly better at PMC intact group. (p < 0.005) but, no statistic difference was seen in clinical outcomes including KT-2000 value, last Lysholm score, posterior drawer test. For PCL ruptures with PMC injuries, treatment for PMC should be considered due to graft status. IV.
