在13个未负重的活膝关节中，我们使用MRI证实了先前在未负重的尸体膝关节屈曲和外旋/内旋期间获得的发现。在7个负重的活膝中，受试者深蹲时，胫骨股骨的相对运动与未负重的膝关节相似，只是股骨内侧髁倾向于向前屈曲约4mm。研究了在外旋和内旋屈曲过程中七个负荷膝盖中的四个。正如预测的那样，胫骨外旋屈（下蹲）抑制了胫骨的内旋，这是在负重屈时观察到的。
In 13 unloaded living knees we confirmed the findings previously obtained in the unloaded cadaver knee during flexion and external rotation/internal rotation using MRI. In seven loaded living knees with the subjects squatting, the relative tibiofemoral movements were similar to those in the unloaded knee except that the medial femoral condyle tended to move about 4 mm forwards with flexion. Four of the seven loaded knees were studied during flexion in external and internal rotation. As predicted, flexion (squatting) with the tibia in external rotation suppressed the internal rotation of the tibia which had been observed during unloaded flexion.
