摘要 目的通过与关节镜对照,探讨磁共振成像(MRI)对原发性膝关节骨关节病的诊断价值。方法观察38例原发性膝关节骨关节病患者MRI上关节软骨、软骨下骨质的异常信号特点及骨质增生情况;分析关节软骨的关节镜与MRI分级之间的相关性。结果共35例患者有髌骨骨质增生,以50岁以下为多见。MRI上关节软骨Ⅰ、Ⅳ级信号少(7、10处),Ⅱ~Ⅲ级信号最多(95处),MRI分级与关节镜分级之间有相关性(r=0.658~0.785;P均〈0.0001),但关节镜下Ⅳ级病灶易被MRI判为Ⅱ~Ⅲ级信号。23例患者出现软骨下骨质异常信号,多发生于髌骨和股骨内髁。结论MRI能清楚显示膝关节骨关节病的病变特点和严重程度。
