Fifty cadaver knees were dissected in order to examine their ligamentous structures and gain an increased understanding of their morphology and their functional contribution to the posterolateral stability of the knee joint. The fabellofibular ligament was found in 34 knee joints (68%); its homologue, the short lateral ligament, was found in only 2 (4%). The arcuate ligament was identifiable in 12 knees (24%) as a thin, membranous capsular structure; more than half of these ligaments lacked either a medial or a lateral limb. The fibular origin of the popliteus was found in 49 knees (98%) with a mean width of 9.3 mm. This strong, tendinous band completes the span of the popliteal tendon between the lateral femoral condyle and the fibular styloid. Based on its course and its relation to the knee joint, we believe it provides static stabilization to the knee by preventing external rotation and posterior translation of the lateral tibial condyle.
为了检查五十具尸体膝关节的韧带结构，并加深对其形态以及对膝关节后外侧稳定性的功能作用的理解，我们对这些膝关节进行了解剖。在34个膝关节（68%）中发现了腓肠豆腓侧韧带；其同源结构，即短外侧韧带，仅在2个膝关节（4%）中被发现。在12个膝关节（24%）中可识别出弓形韧带，它是一种薄的膜性关节囊结构；这些韧带中超过一半缺少内侧或外侧分支。在49个膝关节（98%）中发现了腘肌的腓骨起点，平均宽度为9.3毫米。这条强壮的腱性束带完成了腘肌腱在股骨外侧髁和腓骨茎突之间的跨度。基于其走行及其与膝关节的关系，我们认为它通过防止胫骨外侧髁的外旋和后移为膝关节提供静态稳定作用。
