超声检查在膝关节半月板损伤诊断中的应用价值

Value of ultrasonography in diagnosis of meniscus lesions

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。

Objective To investigate the value of uhrasonography in diagnosis of meniscus lesions. Methods The examination results by uhrasonography 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 uhrasonography,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 Uhrasonography is the main method for diagnosis of menisus lesions because it is noninvasive,convenient and may provide with prompt diagnosis.
