The major supporting structures of the posterolateral knee were noted to be composed of three components: the fabellofibular ligament, the arcuate ligament, and popliteus muscle with origin from fibular head. We classified this area of the knee into seven major anatomic variants. Popliteus tendon is composed of two parts: the anterior and the posterior fibers. The anterior fibers become tight, while the posterior fibers become lax as the knee was flexed. This phenomenon is more pronounced when the tibia is rotated externally. The midpoint between the anterior and the posterior fibers insertions on the femur appeared to be the isometric point of the popliteus tendon.
腓肠豆腓侧韧带、弓状韧带以及起自腓骨头的腘肌。我们将膝关节的这个区域分为七种主要的解剖变异类型。腘肌腱由两部分组成：前纤维和后纤维。当膝关节屈曲时，前纤维收紧，而后纤维松弛。当胫骨向外旋转时，这种现象更为明显。股骨上前后纤维附着点之间的中点似乎是腘肌腱的等长点。
