In 10 patients with an old injury of the anterior cruciate ligament, the three-dimensional movements of the knee joint were studied when the patients flexed their knees. Tibial motions were recorded using roentgen stereophotogrammetric analysis. Internal rotation and adduction of the tibia were reduced in the injured knees when compared with the intact knees; during flexion of the knee joint, the tibial intercondylar eminence occupied a more lateral and posterior position on the injured side. Our results may indicate that the knee joint is continuously exposed to abnormal stresses when the anterior cruciate ligament is torn.
在10例前交叉韧带陈旧性损伤患者中，研究了患者屈膝时膝关节的三维运动。使用X线立体摄影测量分析记录胫骨运动。与健侧膝关节相比，患侧膝关节胫骨的内旋和内收减少；在膝关节屈曲过程中，患侧胫骨髁间隆起处于更外侧和后方的位置。我们的结果可能表明，当前交叉韧带撕裂时，膝关节持续受到异常应力的影响。
