摘　　要：目的：比较高频超声和X线对膝骨性关节炎的临床应用价值。方法：对比高频超声和X线两种检查方法对膝骨性关节炎的诊断符合率,观察膝骨性关节炎的高频超声图像特征。结果：高频超声对膝骨性关节炎的诊断符合率显著高于X线（χ2=7.365,P=0.007）。与治疗前相比髌上囊积液、滑膜厚度经治疗后显著降低（t=47.655,19.199;P=0.000,0.000）;治疗前滑膜血流信号分布比例为0级48.2%、Ⅰ级32.1%、Ⅱ级12.5%,出现腘窝囊肿、软骨破坏、骨质破坏的比例分别为17.9%、100%、100%。治疗后滑膜血流信号分布比例为0级64.3%、Ⅰ级12.5%、Ⅱ级7.1%,出现腘窝囊肿、软骨破坏、骨质破坏的比例分别为3.6%、100%、100%;治疗前X线显示患者发生关节间隙狭窄、骨质增生、关节面囊肿、关节内游离体和半脱位的比例分别为50.0%、42.9%、33.9%、8.9%和10.7%,而治疗后X线显示患者发生关节间隙狭窄、骨质增生、关节面囊肿、关节内游离体和半脱位的比例分别为12.5%、5.4%、8.9%、1.8%和0%。结论：高频超声和X线在临床上均可用于诊断膝骨性关节炎,且高频超声对膝骨性关节炎的诊断符合率显著高于X线。Objective：To compare the clinical value of high frequency ultrasonography and radiography in knee osteoarthritis.Methods：The accuracy of high frequency ultrasonography and radiography in the diagnosis of knee osteoarthritis were compared,and the imaging features of high frequency ultrasonography in the diagnosis of knee osteoarthritis were studied.Results：The accuracy of high frequency ultrasonography in the diagnosis of knee osteoarthritis was obviously higher than that of radiography（χ~2=7.365,P=0.007）.Compared with pre-treatement,the suprapatellar effusion and synovial thickness decreased significantly after being treated（t=47.655,19.199;P=0.000,0.000）;Before treatment,the degree of synovial blood flow signal were grade 0（48.2%）,grade Ⅰ（32.1%）and grade Ⅱ（12.5%）,the occurrence of popliteal cyst,cartilage damage,bone destruction was 17.9%,100% and 100%,respectively.After treatment,the degree of synovial blood flow signal were grade 0（64.3%）,gradeⅠ（12.5%）and gradeⅡ（7.1%）,the occurrence of popliteal cyst,cartilage damage,bone destruction was 3.6%,100%,100%,respectively.Before treatment,joint space narrowing,bone hyperplasia,joint surface cyst,intra-articular loose bodies and subluxation showed on radiography was 50.0%、42.9%、33.9%、8.9% and 10.7%,respectively;while after treatment,which was 12.5%、5.4%、8.9%、1.8%and 0%,respectively.Conclusion：High frequency ultrasonography and radiography could be used in the diagnosis of knee osteoarthritis clinically,and the diagnosis accuracy of high frequency ultrasonography was significantly higher than that of radiography.
