膝关节滑膜病变的高频超声与关节镜对照研究

目的通过与关节镜结果检查对照,评价高频超声对膝关节滑膜病变的诊断价值.方法 68例临床病例,应用高频超声前瞻性观察 72个膝关节滑膜情况,并与关节镜检查结果对照,找出膝关节滑膜疾病的图像特征;并采用双盲法对高频彩超的诊断能力进行评价.结果高频超声诊断膝关节滑膜病变的敏感性为 93.3%、特异性为 90.9%,准确性为 91.7%,阳性预测值为 98.2%及阴性预测值为 71.4%.结论高频超声在术前常规筛选滑膜疾病方面是一种很有价值的影像学方法.

Comparative Study on High-frequency Ultrasound and Arthroscopy in Synovial Diseases of Knee Joint

Objective To evaluate the diagnostic value of high frequency ultrasound in synovial diseases of the knee joint compared with the results of arthroscopy.Methods A total of 68 patients with 72 knee joints were analyzed with high frequency ultrasound and arthroscopy to find out the image characteristics of the synovial diseases and to evaluate the diagnosis ability of ultrasound.Results For the synovial diseases of the knee joint with high frequency ultrasound,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value were 93 3%,90 9%,91 7%,98 2% and 71 4% respectively.Conclusions High frequency ultrasound is a valuable imaging method for diagnosising the synovial diseases of the knee joint in preoperative routine screening.
