Old anteromedial instability of the knee joint causes an increased external rotation of the tibia against the femur. To actively control this tendenoy to increased external rotation, Slocum and Larson advocated the pes anserinus transfer (1968). An increase of rotatory muscle function of 39% after this transfer could be demonstrated experimentally (Noyes and Sonstegard 1973). Contrary to these reports, an increase of rotatory muscle power was rather the exception than the rule in our dynamometric examinations of 49 patients after transfer of the pes anserinus for old anteromedial instability. The reasons for the lack of clinically effective increase in muscle power are discussed. The advancement of the tendon of the semimenbranaceus muscle seems more advantageous as an alternative measure.
膝关节陈旧性前内侧不稳定会导致胫骨相对于股骨的外旋增加。为了积极控制这种外旋增加的趋势，斯洛库姆和拉森主张进行鹅足腱转移术（1968年）。实验证明，这种转移术后旋转肌功能可增加39%（诺伊斯和松斯泰加德，1973年）。与这些报道相反，在我们对49例因陈旧性前内侧不稳定而进行鹅足腱转移术的患者进行的测力检查中，旋转肌力量增加的情况相当少见。文中讨论了肌肉力量缺乏临床有效增加的原因。作为一种替代措施，半膜肌腱的前移似乎更具优势。
