The human posterior cruciate ligament (7 unselected specimens) consists of 2 different bundles with a common tibial attachment: 1. a thin, flat and slightly twisted posterior bundle running to the posterior medial condyle taut in extension and lax in flexion of the knee, 2. a thick oval anterior bundle with parallel fibers running to the roof of the notch lax in extension and taut in flexion. This contra-tensile function explains the different posterior instability in extension or flexion of the knee in case of an isolated rupture of only 1 of these bundles.
人类后交叉韧带（7个未选标本）由2个不同的束组成，胫骨附着点相同：1. 一条薄、扁平且略有扭曲的后束，延伸至后内侧髁，膝关节伸直时紧张，屈曲时松弛；2. 一条厚的椭圆形前束，纤维平行，延伸至髁间窝顶部，伸直时松弛，屈曲时紧张。这种抗张功能解释了在这些束中仅有1条孤立断裂时，膝关节伸直或屈曲时不同的后向不稳定情况。
