Although the popliteofibular ligament (PFL) is an important posterolateral structure of the knee joint, the anatomical characteristics of this ligament remain unclear. We morphologically classified and measured the PFLs from 78 cadaver knees. The PFL was observed in all knees, and it was classified into type I (with one layer) or type II (with two layers). The mean lengths of the anterior and posterior margins were 12.7 and 6.8 mm, respectively; and the mean width and thickness were 10.4 mm and 2.1 mm, respectively. The PFL inclined forward at a mean sagittal angle of 20.7 degrees, which is similar to the 21.2 degrees of the posterior cruciate ligament, indicating that the PFL contributed to posterolateral rotatory stability.
尽管腘腓韧带（PFL）是膝关节重要的后外侧结构，但其解剖学特征仍不明确。我们对78具尸体膝关节的腘腓韧带进行了形态学分类和测量。所有膝关节均观察到腘腓韧带，其分为I型（单层）或II型（双层）。前缘和后缘的平均长度分别为12.7毫米和6.8毫米；平均宽度和厚度分别为10.4毫米和2.1毫米。腘腓韧带在矢状面上平均向前倾斜20.7度，与后交叉韧带的21.2度相似，表明腘腓韧带有助于后外侧旋转稳定性。
