The purpose of this article is to present the incidence of posterior cruciate ligament (PCL) injuries in trauma patients with acute hemarthrosis of the knee. There were 222 acute knee injuries with hemarthrosis presented to our regional trauma center over a 38-month period. PCL injuries occurred in 38% (85 of 222) acute knee injuries; 56.5% (48 of 85) were trauma patients, and 32.9% (28 of 85) were sports related. Higher energy mechanisms may account for the difference. Isolated PCL injuries were rare (3.5%, 3 of 85), whereas 96.5% (82 of 85) of PCL injuries occurred in combination with other ligament injuries. Trauma patients have a higher incidence of PCL injuries than do athletes. Acute knee hemarthrosis in trauma patients should elevate suspicion for multiple knee ligament injuries involving the posterior cruciate ligament.
本文旨在呈现膝关节急性血肿的创伤患者中后交叉韧带（PCL）损伤的发生率。在38个月的时间里，有222例伴有血肿的急性膝关节损伤患者被送至我们地区的创伤中心。在222例急性膝关节损伤中，PCL损伤发生率为38%（85例中的85例）；其中56.5%（85例中的48例）为创伤患者，32.9%（85例中的28例）与运动相关。更高能量的机制可能解释了这种差异。单纯PCL损伤很少见（85例中的3例，占3.5%），而96.5%（85例中的82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。创伤患者出现急性膝关节血肿时，应提高对涉及后交叉韧带的多膝关节韧带损伤的怀疑。
