The anterolateral and anteromedial stability of seventeen fresh frozen cadaver knees was studied in a test apparatus designed to simulate physiological conditions. Statistically significant increases in internal rotation occurred in seven knees when only the anterior cruciate ligament was sectioned, and these increases were enhanced by subsequent sectioning of the posterolateral complex and the lateral collateral ligament, singly or in combination. On the other hand, sectioning of the posterolateral complex and of the lateral collateral ligament, leaving the anterior cruciate intact, did not produce significant increases in internal rotation until the anterior cruciate ligament was sectioned in seven knees. When the entire anterolateral capsule was sectioned as far posterior as the lateral collateral ligament in three knees, no changes in internal or external rotation occurred. Only when the posterolateral complex was sectioned was there a significant increase in external rotation in any of the ligament-sectioning sequences. Thus, it appears that for pathological internal rotation of the tibia on the femur to occur, the anterior cruciate ligament must be incompetent.
The test apparatus and the results are useful in assessing which ligament structures contribute to clinically noted rotational knee instabilities.
在一个旨在模拟生理状况的测试装置中，对17个新鲜冷冻尸体膝关节的前外侧和前内侧稳定性进行了研究。当仅切断前交叉韧带时，7个膝关节出现了具有统计学意义的内旋增加，并且在随后单独或联合切断后外侧复合体和外侧副韧带时，这些增加更为明显。另一方面，在7个膝关节中，在前交叉韧带完整的情况下切断后外侧复合体和外侧副韧带，直到切断前交叉韧带后才出现显著的内旋增加。当在3个膝关节中将整个前外侧关节囊向后切断至外侧副韧带时，内旋或外旋均未发生变化。只有在切断后外侧复合体时，在任何韧带切断顺序中才会出现显著的外旋增加。因此，似乎要发生胫骨在股骨上的病理性内旋，前交叉韧带必须功能不全。
该测试装置和结果有助于评估哪些韧带结构导致临床上所观察到的膝关节旋转不稳。
