Discoid meniscus (DM) is currently considered as a spectrum of disorders in meniscal shape and stability. Diagnosing DM on MR imaging has clinical and surgical implications. When diagnosing a DM on MR imaging, identification of tears and signs of instability is of utmost importance. The literature has focused on the diagnosis of DM based on morphology as complete, incomplete, and Wrisberg type, the latter lacking posterior attachments. This article reviews the relevant anatomy, histology, and clinical presentation of DM in the pediatric population.
盘状半月板（DM）目前被认为是半月板形状和稳定性方面的一系列病症。在磁共振成像（MR）上诊断DM具有临床和手术意义。在MR成像上诊断DM时，识别撕裂和不稳定迹象至关重要。文献主要关注基于形态学将DM诊断为完全型、不完全型和Wrisberg型，后者缺乏后附着点。本文综述了儿童人群中DM的相关解剖学、组织学和临床表现。
