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.

本研究旨在评估后交叉韧带（PCL）断裂后采用跟腱异体移植重建PCL时，后内侧角（PMC）损伤对临床疗效及二次关节镜检查结果的影响。
回顾性纳入2009年至2019年期间因PCL断裂接受关节镜下PCL重建及二次关节镜检查的51例患者。将研究对象分为两组：PMC完整组31例患者；PMC损伤组18例患者。随访至少1年，评估临床疗效及关节镜检查结果，包括滑膜覆盖情况、张力等。
关节镜检查结果，包括滑膜覆盖情况、张力，在PMC完整组明显更好。（p<0.005）但是，在包括KT-2000值、末次Lysholm评分、后抽屉试验等临床疗效方面未观察到统计学差异。
对于合并PMC损伤的PCL断裂，应根据移植物状态考虑对PMC进行治疗。
IV级。
