The posterior cruciate ligament (PCL) is one of the four major stabilizers of the knee joint and functions as the primary restraint to posterior tibial translation. PCL tears rarely occur in isolation and most commonly presents in the setting of multiligamentous knee injuries. Several treatment strategies for these injuries have been proposed over the last decades, including ligament reconstruction and primary repair. Arthroscopic primary PCL repair has the potential to preserve native tissue using a more minimally invasive approach, thereby avoiding donor-site morbidity and allowing early mobilization. While arthroscopic PCL repair is certainly not an effective surgical approach for all patients, this procedure may be a reasonable and less morbid alternative to PCL reconstruction in selected patients treated for proximal or distal avulsion tears, with low failure rates, good knee stability, and good to excellent subjective outcomes. The surgical indications, surgical techniques, postoperative management, and outcomes for arthroscopic primary repair of proximal and distal PCL tears will be discussed in this review.
后交叉韧带（PCL）是膝关节的四个主要稳定器之一，作为胫骨后移的主要限制物。PCL 撕裂很少单独发生，最常见于多韧带膝关节损伤。过去几十年提出了几种治疗这些损伤的策略，包括韧带重建和初步修复。关节镜下 PCL 初步修复有可能通过更微创的方法保留原生组织，从而避免供体部位的发病率，并允许早期活动。虽然关节镜 PCL 修复对所有患者都不是一种有效的手术方法，但对于接受近端或远端撕脱伤治疗的选定患者，该手术可能是一种合理且较少产生病变的替代 PCL 重建方法，其失败率低、膝关节稳定性好、主观疗效好至优秀。本文将讨论关节镜下治疗近端和远端 PCL 撕裂的初步修复的手术适应证、手术技术、术后管理和结果。
