Abstract

The meniscal roots and supporting structures anchor the menisci to the tibial plateau and resist hoop stress, thereby preventing radial displacement of the menisci and secondary degenerative tibiofemoral compartment changes that may occur if this is compromised. The anatomy of the four meniscal roots and their supporting structures on magnetic resonance imaging (MRI) will be outlined in this review article, as well as the imaging appearances of meniscal root–related pathology, namely meniscal root degeneration and tears, meniscal extrusion and tibial plateau cystic lesions.

半月板根的磁共振成像

摘要

半月板的根部和支撑结构将半月板锚固到胫骨平台并抵抗环向应力，从而防止了半月板的径向移位和继发性退行性胫股间隔的改变，如果这种改变会发生。本文将概述这四个半月板根的解剖结构及其在磁共振成像（MRI）上的支撑结构，以及与半月板根相关的病理学影像学表现，即半月板根部退化和撕裂，半月板挤压和胫骨高原囊性病变。
