The significance of the posterior cruciate ligament in the stability of the knee was investigated in dogs and it was compared with that of the anterior cruciate ligament by studying the changes produced in the knee after transection of either ligament. Osteophyte formation and changes in articular cartilage were less prominent after division of the posterior cruciate ligament. A complete longitudinal tear of the medial meniscus was found in eight out of the 10 dogs who had undergone section of the anterior cruciate but in none of the 10 with section of the posterior cruciate. It appears that, in dogs at least, the posterior cruciate ligament is less important than the anterior in the stability of the knee.
研究人员在犬类中对后交叉韧带在膝关节稳定性中的意义进行了调查，并通过研究切断任何一条韧带后膝关节所产生的变化，将其与前交叉韧带的意义进行了比较。切断后交叉韧带后，骨赘形成和关节软骨变化不那么明显。在接受前交叉韧带切断术的10只犬中，有8只出现了内侧半月板完全纵向撕裂，但在接受后交叉韧带切断术的10只犬中均未出现。至少在犬类中，后交叉韧带在膝关节稳定性方面似乎不如前交叉韧带重要。
