摘　　要：目的:进行膝关节骨性关节炎X线测量与WOMAC评分的多重线性回归分析,结合临床和生物力学分析两者的关系。方法:自2011年3月至2011年7月,膝关节骨性关节炎患者140例250膝,左侧132膝,右侧118膝;年龄40～71岁,平均54.68岁。应用MB-RULER测量软件测量患膝正侧位X线片股骨角、胫骨角、股胫角及关节间隙角等数值,并采集WOMAC评分,应用多重线性回归建立回归方程分析两者相关性。结果:应用多重线性回归分析正位X线片测量数值与WOMAC评分的回归方程有统计学意义(P<0.05),而侧位X线片测量数值与WOMAC评分的回归方程无统计学意义(P>0.05)。结论:①膝关节X线数据测量可以一定程度上反映WOMAC评分的情况;②局部膝关节X线力线测量对诊治膝关节骨性关节炎是必须的检查之一,应予以重视。③正位片上胫骨角、关节间隙角与WOMAC评分的相关性最大,可用于评估患者在治疗前后的功能恢复情况。Objective：To perform Multiple Linear Regression analysis of X-ray measurement and WOMAC scores of knee osteoarthritis,and to analyze their relationship with clinical and biomechanical concepts. Methods：From March 2011 to July 2011,140 patients（250 knees） were reviewed,including 132 knees in the left and 118 knees in the right;ranging in age from 40 to 71 years,with an average of 54.68 years. The MB-RULER measurement software was applied to measure femoral angle,tibial angle,femorotibial angle,joint gap angle from antero-posterir and lateral position of X-rays. The WOMAC scores were also collected. Then multiple regression equations was applied for the linear regression analysis of correlation between the X-ray measurement and WOMAC scores. Results：There was statistical significance in the regression equation of AP X-rays value and WOMAC scores（P〈0.05）,while there was no statistical significance in the regression equation of lateral X-ray value and WOMAC scores（P〉0.05）. Conclusion：① X-ray measurement of knee joint can reflect the WOMAC scores to a certain extent. ② It is necessary to measure the X-ray mechanical axis of knee,which is important for diagnosis and treatment of osteoarthritis. ③ The correlation between tibial angle,joint gap angle on antero-posterior X-ray and WOMAC scores is significant,which can be used to assess the functional recovery of patients before and after treatment.
