The posterior cruciate ligament, situated near the center of the knee, functions as the basic stabilizer and is located close to the axis of motion. We diagnosed and repaired thirty-two consecutive acute tears of the posterior cruciate ligament associated with tears of medial or lateral-compartment ligaments, or of both. Of the twenty-nine knees that we could evaluate, twenty-three demonstrated a 2+ to 3+ positive abduction or adduction stress test done in maximum extension and a positive anterior drawer test done in maximum internal rotation, while only nine had a definitely positive posterior drawer test. In all knees we repaired the tears, using the medial meniscus as a graft in nine knees in which the repair of the posterior cruciate ligament did not produce immediate adequate stability at operation. Five to sixteen years after operation, twenty of these twenty-nine knees were available for evaluation. The objective results were good in thirteen, fair in four, and poor in three.
后交叉韧带位于膝关节中心附近，作为基本的稳定结构，靠近运动轴。我们连续诊断并修复了32例与内侧或外侧半月板韧带撕裂或两者均有撕裂相关的急性后交叉韧带撕裂。在我们能够评估的29个膝关节中，23个在最大伸展时进行的外展或内收应力试验为2+至3+阳性，在最大内旋时进行的前抽屉试验为阳性，而只有9个后抽屉试验明确为阳性。在所有膝关节中，我们都修复了撕裂，在9个膝关节中使用内侧半月板作为移植物，这些膝关节在后交叉韧带修复时在手术中未立即产生足够的稳定性。术后5至16年，这29个膝关节中有20个可供评估。客观结果为良好的有13个，一般的有4个，差的有3个。
