The posterior cruciate ligament (PCL) is an anatomically and biomechanically complex structure. PCL injuries are reported to occur in 1-40% of acute knee injuries, with isolated PCL tears less common that PCL tears combined with other ligament injuries. Diagnosis of PCL injuries requires a high index of suspicion, careful physical examination, imaging studies, and systematic arthroscopic evaluation. Surgical reconstruction is recommended for acute PCL tears combined with other ligament or structural injuries, and when there is a negative tibial step off in an isolated PCL tear. Isolated acute PCL tears with a positive tibial step off or flat tibial step off may be treated with rehabilitation and observation and reconstructed later if symptomatic. Arthroscopic techniques of PLC reconstruction are becoming more refined and reproducible and may increase the predictability of this surgery. Carefully documented pre- and postoperative evaluations are required to judge the effectiveness of PCL reconstructive procedures.
后交叉韧带（PCL）是一种在解剖学和生物力学上都很复杂的结构。据报道，PCL损伤在1%至40%的急性膝关节损伤中出现，孤立的PCL撕裂比PCL撕裂合并其他韧带损伤的情况少见。PCL损伤的诊断需要高度的怀疑指数、仔细的体格检查、影像学检查以及系统的关节镜评估。对于急性PCL撕裂合并其他韧带或结构损伤，以及孤立PCL撕裂时胫骨后沉阴性的情况，建议进行手术重建。孤立的急性PCL撕裂伴有阳性胫骨后沉或胫骨后沉平坦时，可先进行康复治疗和观察，如有症状可在后期进行重建。PCL重建的关节镜技术正变得更加精细和可重复，可能会提高该手术的可预测性。需要仔细记录术前和术后评估，以判断PCL重建手术的效果。
