摘　　要：目的通过膝关节损伤的磁共振成像(MRI)表现和膝关节镜结果的比较,得出MRI定性诊断膝关节损伤的敏感性和准确性,评价MRI在膝关节损伤诊断中的价值。方法选取我院2014年1月至12月完整的112例膝关节损伤的手术记录和本院MRI检查结果,并将两者作对比。结果以膝关节镜为金标准,112例中,韧带损伤伴断裂或撕裂62例,MRI检查的符合率为90.3%;内外侧半月板复杂性损伤86个(包括纵形、水平撕裂,桶柄状损伤),MR检查为3度损伤有88个,符合率92.8%;盘状半月板31例;MRI检查的符合率为90.3%。结论 MRI是对韧带,半月板损伤的无创性检查,其敏感性、特异性、准确性都较高,提示韧带轻度损伤以及半月板的Ⅰ-Ⅱ级损伤,须慎行膝关节检查。Objective On the basis of comparing MRI performance of knee injuries and knee arthroscopy re-sults ,it was found that MRI have high sensitivity and accuracy for the diagnosis of knee injury , and also can evalu-ate the value of the knee injury diagnosis. Methods Retrospectively analyze complete surgical recording and MRI findings of 112 cases with knee injury from January 2014 to December 2014 ,then compare the diagnosis. Results Knee arthroscopy was regarded as a gold standard,of 112 cases, there were 62 cases of ligament injury with fracture or tear, with the coincidence of 90.3% by MRI,86 cases of medial and lateral meniscus complex injury (including lon-gitudinal, horizontal tear and bucket handle-like injury), 3 cases of Level 3 injury by MR, with the coincidence of 92.8%; 31 cases of discoid meniscus with the coincidence of 90.3% by MRI. Conclusion MRI is a noninvasive ex-amination for ligament and meniscus injury with high sensitivity, specificity and accuracy, which suggests that a mild ligament injury andⅠ-Ⅱgrade meniscus damage should underwent knee examination with cautious.
