膝关节及周围常见疾病的超声诊断研究

Study on ultrasonic diagnosis of common diseases of knee joint or knee joint peripheral

目的:探讨超声检查对膝关节及周围常见疾病的诊断价值。方法:运用超声对膝关节及周围常见疾病进行诊断。结果:对21例窝囊肿和20例窝脂肪瘤及11例膝关节腔积液的超声检查结果与手术病例证实,符合率达100%;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,超声检查准确做出半月板损伤诊断38个,漏诊8个,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、诊断膝关节及周围疾病的准确性较高,可作为基层医院一种广泛开展的检查方法。

Objective：To investigate the value of ultrasonography in diagnosis of common diseases of the knee joint or knee joint peripheral.Methods：Aceording to the results of 20 cases of popliteal fessa cysts and 21 cases of popliteal fossa lipoma as well as 11 cases of articular effusion of knee joint ultrasonography proved by surgical pathology, the diagnostic accordance rate was 100%. The examination results by ultrasonography were compared with those of arthroscopic operation. Results： Forty - six meniseal lesions were diagnosed by arthroscopie operation, and 38 of which were actually diagnosed by ultrasonography, and 8 meniscal lesions were mis - diagnosed. Actual - negative were found in 97 meniscus, falsepositive 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 %. Condu^ons： Ultrasonography is the main method for diagnosis of meniscus lesions because it is noninvasive, convenient and may provide with prompt diagnosis. The CT examination and arthroscopy in big hospital are unnecesary, patients can avoid economic losses and delaying treatment time.
