     摘要：目的探讨超声检查对膝关节半月板损伤的诊断价值。方法对74例膝关节共148个半月板超声检查结果与关节镜检查结果进行对照分析。结果 148个半月板中，关节镜发现半月板损伤46个，超声检查准确作出半月板损伤诊断38个，漏诊8个，真阴性97个，假阳性5个。超声诊断半月板损伤的准确率91.2%，敏感性82.6%，特异性95.1%，阳性结果预测值88.4%，阴性结果预测值92.4%。结论超声检查无创、方便、及时，诊断半月板损伤准确性较高，容易广泛开展，可作为诊断半月板损伤的一种重要检查方法。

    Abstract： Objective To investigate the value of ultrasonography in diagnosis of meniscus lesions.Methods The examination results by ultrasonography were compared with that of arthroscopic operation.Results Fortysix meniscal lesions were diagnosed by arthroscopic operation,and 38 of which were actually diagnosed by ultrasonography,and 8 meniscal lesions were misdiagnosed.Aactualnegative were found in 97 meniscus,falsepositive in 5 lesions.For all meniscal lesions,the accuracy of ultrasound was 91.2%,sensitivity 82.6%,specificity 95.1%,positive predictive value 88.4%,negative predictive value 92.4%.Conclusion Ultrasonography is the main method for diagnosis of menisus lesions because it is noninvasive,convenient and may provide with prompt diagnosis. ......
