A study of 246 adult nonhuman primates belonging to 34 genera indicates that a popliteal sesamoid bone is always present in the tendon of the popliteus muscle in Prosimii and Callitrichidae. The bone occurs only variably in Atelidae and Pongo, and is usually absent in Gorilla. The bone is absent, or very rare, in Cebus, Cercopithecidae, Hylobatidae, Pan, and humans. When the bone is present, it articulates with the posterior part of the articular surface of the lateral condyle of the tibia, and lies very close to the head of the fibula, at the angulated part of the popliteal tendon, near the tendomuscular junction. The presence of the popliteal sesamoid bone in primates is a primitive character.
一项对属于34个属的246只成年非人类灵长类动物的研究表明，在原猴亚目和狨科动物中，腘肌肌腱内始终存在一块腘籽骨。这块骨头在蛛猴科和猩猩属中出现情况不一，在大猩猩中通常不存在。在卷尾猴属、猕猴科、长臂猿科、黑猩猩属和人类中，这块骨头不存在或非常罕见。当这块骨头存在时，它与胫骨外侧髁关节面的后部相连，位于腘肌腱成角部分靠近肌腱与肌肉连接处，非常靠近腓骨头。灵长类动物中腘籽骨的存在是一个原始特征。
