Abstract

Ring meniscus is a known but rare abnormal variant of a meniscus. An incomplete discoid meniscus or an old bucket handle tear of a meniscus can be easily mistaken for a ring meniscus. In this case; during the first arthroscopy, the ring lateral meniscus was mistaken for an incomplete discoid lateral meniscus. On repeat arthroscopy, it was confirmed as ring lateral meniscus.

摘要

半月板环形撕裂是一种已知但罕见的半月板异常变异。不完整的盘状半月板或半月板陈旧性桶柄样撕裂容易误诊为半月板环形撕裂。在此病例中，初次关节镜检查时，外侧半月板环形撕裂误诊为不完整的盘状外侧半月板。再次进行关节镜检查时，确诊为外侧半月板环形撕裂。
