The meniscal ossicle is an infrequent radiographic finding in humans. It has long been recognized in relation to trauma to the meniscus. Previous theories as to the etiology of these ossicles have been that they are vestigial or result from metaplastic change in an area of injury. We present four patients with meniscal ossicles associated with a longitudinal tear of the medial meniscus. The origin of the ossicle was an avulsion of the insertion of the posterior horn of the medial meniscus. Arthroscopic resection in these patients resolved their symptoms.
半月板小骨在人类中是一种罕见的影像学表现。长期以来，它一直被认为与半月板创伤有关。以往关于这些小骨病因的理论认为，它们是退化残留的，或是由损伤区域的化生改变所致。我们报告了4例伴有内侧半月板纵向撕裂的半月板小骨患者。小骨起源于内侧半月板后角附着处的撕脱。对这些患者进行关节镜下切除后症状得以缓解。
