摘要： 目的分析局灶性关节软骨损伤的MRI所见。方法按国际软骨修复协会(ICRS)分级法对68个病灶的MRI所见进行分析,着重观察关节软骨和软骨下骨的改变。结果58个分级为Ⅰ级2个,Ⅱ级5个,Ⅲ级14个,Ⅳ级37个;10个病灶属于剥脱性骨软骨炎Ⅰ级。MRI能发现关节镜无法观察到的软骨下骨病变。结论MRI对局灶性骨软骨损伤的显示准确。

Abstract: Objective To analyze the feature of joint osteochondral lesions under the magnetic resonance imaging (MRI). Methods The finding under MRI in the 68 focal osteochondral lesions were classified with the International Cartilage Repair Society (ICRS) classification, with the emphasis on articular cartilage and subchondral bone lesion.Results 58 lesions were classified as 4 grades: 2 focus of grade Ⅰ, 5 of grade Ⅱ, 14 of grade Ⅲ, 37 of grade Ⅳ. Other 10 focuses were grade Ⅰ of osteochondritis dissecans. MRI can discover subchondral bone lesion which couldn't be observed with arthroscopy. Conclusion MRI can accurately show the focal osteochondral lesions.

Key words: articular cartilage, osteochondral injury, magnetic resonance imaging (MRI)
