The purpose of this article is to evaluate the incidence of posterior cruciate ligament (PCL) injuries in trauma patients with acute hemarthrosis of the knee. Sixty-one acute knee injuries underwent examination under anesthesia and diagnostic arthroscopy at a tertiary care trauma center over an 11-month period. PCL injuries occurred in 44% (27 of 61) acute knee injuries; 81.5% (22 of 27) were trauma patients and 18.5% (five of 27) were sports related. Higher energy mechanisms of injury may account for the difference. Isolated PCL injuries were rare [7.5% (two of 27)], whereas 92.5% (25 of 27) of PCL injuries occurred in combination with other ligament injuries. Trauma patients have a higher incidence of PCL injuries than does the athletic population. Acute knee hemarthrosis in trauma patients should elevate suspicion for PCL injuries. Arthroscopy is a valuable tool for PCL evaluation and surgical planning.
本文旨在评估膝关节急性血肿创伤患者后交叉韧带（PCL）损伤的发生率。在一家三级创伤中心，对61例急性膝关节损伤患者在11个月的时间内进行了麻醉下检查和诊断性关节镜检查。PCL损伤发生在44%（61例中的27例）的急性膝关节损伤中；81.5%（27例中的22例）为创伤患者，18.5%（27例中的5例）与运动相关。更高能量的损伤机制可能解释了这种差异。孤立的PCL损伤很少见[7.5%（27例中的2例）]，而92.5%（27例中的25例）的PCL损伤与其他韧带损伤同时发生。创伤患者PCL损伤的发生率高于运动员群体。创伤患者的急性膝关节血肿应提高对PCL损伤的怀疑。关节镜检查是评估PCL和进行手术规划的有价值工具。
