摘要
目的探讨彩色多普勒超声对中老年膝骨关节炎的临床诊断价值。方法选取我院临床诊断为膝骨关节炎患者60例,均行膝关节超声、MRI检查及关节镜手术,将膝关节超声与MRI检查结果进行比较,并以其关节镜手术后诊断为金标准,分析超声诊断膝骨关节炎的特异性和敏感性。结果超声与MRI在诊断滑膜增厚、关节积液、腘窝囊肿、副韧带损伤及肌腱断裂病变间差异无统计学意义;超声对半月板病变及交叉韧带病变方面的诊断准确率较MRI低。MRI与超声诊断膝骨关节炎的敏感性和特异性分别为78.31%、89.19%和69.88%、91.89%;超声诊断膝骨关节炎的敏感性低于MRI,但特异性高于MRI,差异均有统计学意义(均P<0.05)。结论超声检查对中老年膝骨关节炎的诊断具有较高特异性,可作为关节病患者的筛选手段。
Objective To investigate the clinical diagnostic value of color Doppler ultrasound in older patients with senile knee joint osteoarthritis.Methods Sixty cases with knee joint osteoarthritis were enrolled. All patients were performed knee ultrasound,MRI and arthroscopic surgery,and the results of knee ultrasound and MRI were compared with arthroscopic surgery,the specificity and sensitivity of ultrasonic in diagnosis of knee joint disease were analyzed.Results In synovial thickening,joint effusion,popliteal fossa cyst,the collateral and ligamen,and ruptue of tendons pathological changes,the difference between ultrasound and MRI was not significant,and the diagnostic accuracy of MRI in the meniscus lesions and cruciate ligament was higher than that of ultrasound. The sensitivity and specificity of MRI in diagnosis of knee joint osteoarthritis were 78.31% and89.19%,respectively. The sensitivity and specificity of ultrasound were 69.88% and 91.89%,respectively. The sensitivity of ultrasound in diagnosis of knee joint osteoarthritis was lower than that of MRI,but the specificity was higher than that of MRI,and the difference was significance（P〈0.05）.Conclusion Ultrasound in diagnosis of senile knee joint osteoarthritis with high specificity and can be used as screening approaches for older patients with arthritis.
