摘　　要：目的探讨半月板边缘部垂直撕裂对诊断前交叉伽带（ACL）损伤的价值。方法回顾性分析经关节镜证实的149例半月板撕裂的膝关节MRI结果，判断半月板撕裂的形态、位置以及前交叉韧带的情况。结果149例半月板撕裂膝关节中，34个膝关节共36个半月板撕裂（其中2个膝关节内、外侧半月板同时撕裂），MRI显示为半月板边缘部垂茸撕裂类型，其中29个膝关节同时伴有前交叉韧带损伤。其余115个膝关节，MRI显示为其他半月板撕裂类型．其中49例膝关节同时伴有前交义韧带损伤。膝关节半月板边缘部垂直撕裂类型与其他的半月板撕裂类型比较，其合并前交叉韧带损伤的发生率分别为85．3％及42．6％，两者间具有显著性差异（χ2=19．2，P〈0．01）。半月板边缘部垂直撕裂提示膝关节前交叉韧带损伤的敏感性、特异性和阳性似然比分别为37．2％、93．0％和5．3。结论半月板边缘部垂直撕裂大部分合并有ACL损伤。Objective To explore the relationship between peripheral vertical meniscus tears and anterior cruciate ligament （ACL） tears in knee joints. Methods MRI findings in 149 cases with meniscus tears proved by arthroscopy were analysed. The location and morphology of the meniscus tears and the ACL injury were observed. Results Among 149 cases, 36 peripheral vertical meniscus tears in 34 knees（both medial and lateral meniscus tear in 2 cases） ,and in company with ACL injury in 29 knees were showed by MR imaging. In 115 knees with other patterns of meniscus tears, there were 19 cases with ACL injury. The difference of the prevalence of ACL injury between meniscus tears of the peripheral vertical pattern （85.3 %） and other patterns （42.6 %） was statistically sig- nificant （χ2=19.2,P〈0.01）. The sensitivity, specificity and positive likelihood ratio with peripheral vertical tears of meniscus in detecting ACL injury were 37.2%, 93.0% and 5.3, respectively. Conclusion Most of peripheral vertical meniscus tears is accompa- nied with ACL injury.
