Abstract： 目的 分析青少年急性单纯膝关节软骨骨折的MRI表现,以提高对MRI表现的认识.方法 回顾性分析经关节镜手术证实的26例27处急性单纯膝关节软骨骨折的MRI表现,重点观察软骨、软骨下低信号线和软骨下骨髓的改变.26例均采用矢状面和冠状面扫描,矢状面应用快速小角度激发成像序列T1WI加脂肪抑制(FLASH-FS-T1WI)、SE-T1WI和三维稳态进动快速成像序列T2WI加脂肪抑制(FISP-3D-FS-T2WI)序列,冠状面应用多回波数据结合成像序列T2WI(ME-T2WI)和SE-T1WI,有5例还加扫了横轴面ME-T2WI.结果 26例27处软骨骨折中髌骨8处,股骨内髁7处,股骨外髁11处,胫骨平台1处.单纯软骨骨折有3种类型,软骨全层缺损(7处,其中髌骨3处、股骨内髁2处、股骨外髁1处、胫骨平台外后髁1处)、裂隙状软骨骨折(3处,其中股骨内髁2处、股骨外髁1处)、软骨部分缺损(17处,其中髌骨5处、股骨内髁3处、股骨外髁9处).关节镜手术发现21例有关节内软骨游离体,而MRI仅发现3例.全部患者软骨骨折附近均有骨髓挫伤,软骨下低信号线形态、信号均正常.结论 膝关节股骨和胫骨平台软骨骨折采用矢状面FLASH-FS-T1WI、SE-T1WI和FISP-3D-FS-T2WI序列及冠状面ME-T2WI、SE-T1WI,髌骨软骨骨折加扫横轴面ME-T2WI序列可显示急性单纯膝关节软骨骨折的部位、范围和类型,是软骨骨折最好的无创性检查方法.
