摘　　要：目的探讨膝关节半月板撕裂的MRI诊断价值。方法收集并分析经关节镜证实的60例膝关节半月板撕裂的MRI表现,并参考Stoller分级方法,提出半月板损伤的4级分法。结果60例65个半月板撕裂中,内侧撕裂15个,外侧撕裂40个,两侧同时撕裂5例10个。合并外侧盘状半月板15个。MRI诊断准确率为90.8%。39例出现合并症,伴随病变有韧带撕裂,骨挫伤,关节积液,骨折,半月板囊肿等。结论MRI能够准确诊断半月板撕裂,还能发现多种合并症。Objective To evaluate the value of MRI in diagnosis of meniscus tear of knee joint. Methods MRI manifestations of meniscus tear of knee joint were analyzed in 60 cases . Four - grade classification of meniscus injury was suggested according tO Stoller＇ s classi- fication. Results Meniscus tear was seen in 65 menisci of 60 patients, including 15 medial tear,40 lateral tear, and 5 cases（ n = 10）of bilateral tear. Fifteen lateral discoid menisci were found among the 60 cases of meniscus tear. MRI revealed a accuracy of 90.8%. Thirty - nine cases were complicated by ligament injury,bone contusion,effusion of joint,fracture and meniscus cyst. Conclusion MRI can accurately diagnose meniscus tear and its complication.
