摘　　要：目的：分析膝关节剥脱性骨软骨炎（OCD）的MRI表现特征，提高对其MRI影像表现的认识。方法收集39例经手术或膝关节镜证实的膝关节OCD的MRI影像资料，回顾分析其MRI表现，并与手术或膝关节镜所见对比分析。结果病变位于股骨内侧髁29例，外侧髁7例，内外侧髁同时受累3例，合并胫骨平台病变5例、髌骨病变7例。MRI表现为关节软骨下骨板变薄或消失、坏死骨，局部软骨变薄、毛糙，部分可见病变骨组织及表面软骨与宿主骨分离、脱落形成游离体，与手术或膝关节镜下所见基本一致。结论膝关节OCD的MRI征象出现早，具有一定特征性，能较好反映病变的病理改变，可作为该病的首选检查方法。ObjectiveTo evaluate MRI charateristics of the knee joint osteochondirtis dissecans（OCD）.MethodsRetrospective analysis of 39 cases MRI that were confirmed OCD by knee arthroscopy and operation,and evaluated the imaging charateristics of OCD.ResultsThe lesions occurred mostly in the medial femoral condyle（29）followed by the lateral femoral condyle（7）,The lesions occurred in the medial and lateral femoral condyle（3）,with tibial plateau（5）,and patella（7）. MRI showed the performance of subchondralfocal focal small lesions, the subchondral bone plate thinned or disappeared,part of articular cartilage fractured or vanished or formed loose body. Theer was high correlation between the MRI manifestation and arthroscopy or operation.Conclusions OCD in the knee has specific MRI manifestations with high arthroscopic correlation and can be diagnosed by MRI.
