摘　　要：目的:探讨运动性膝关节软骨损伤的磁共振成像表现及其临床应用价值。材料与方法:回顾性分析40例运动性膝关节软骨损伤患者的磁共振各序列图像资料,并与关节镜及手术结果相对照研究。结果:MRI FSPD/T2序列发现软骨损伤60处,敏感度为89.7%,特异度为96.7%,阳性预测值为89.2%,阴性预测值为97.4%。结论:MRI FS-PD/T2序列能准确的判断软骨损伤的范围和深度,与关节镜检查一致性高,并能发现关节镜不能提示的软骨下骨质结构损伤等。Purpose： To in investigate the manifest and application on magnetic resonance imaging （MRI） of motility injury of knee joint cartilage. Materials and Methods： Each MRI subsequence informations of 40 patients with motility injury of knee joint cartilage were retrospectively analyzed and compared with operation results. Results： 60 places of cartilage inju- ries were found by MRI FS - PD/T subsequence which had 89. 7% of sensitivity, 96. 7% of specificity, 89. 2% of positive predictive value and 97.4% of negative predictive value. Conclusion ： The length and depth of cartilage injuries were exactly judged by MRI FS - PD/T2 subsequence consistent with result of arthroscopes examination and also found the selerotin injuries under cartilage rather than found by arthroscopes examination.
