Discoid meniscus is a well-known meniscal dysmorphia affecting more often the lateral meniscus of the knee. Familial series are exceptional with only two reported instances. A new series of three bilateral symptomatic cases of lateral discoid menisci was reported in a family of three brothers and sisters, whom parents had never suffered from their knees. During operative procedure four complete and two incomplete types were found. Two complete and four partial meniscectomies have been performed followed by four good results in the five with sufficient follow-up. The origin of this malformation is unknown. The phylogenetic and ontogenetic studies give no explanation and genetic factors seem to have a minor role.
盘状半月板是一种众所周知的半月板畸形，更常影响膝关节的外侧半月板。家族性病例极为罕见，仅有两例报道。本文报道了一个新的系列病例，涉及三兄弟姊妹家庭中的三例双侧有症状的外侧盘状半月板病例，他们的父母从未有过膝关节相关疾病。手术过程中发现了四例完全型和两例不完全型。进行了两例完全半月板切除术和四例部分半月板切除术，在五例有足够随访时间的病例中，四例效果良好。这种畸形的起源尚不清楚。系统发育和个体发育研究均无法给出解释，遗传因素似乎作用较小。
