摘    要:目的:探讨膝骨关节炎患者体重指数与双下肢力线的关系。方法:2008年7月至2010年6月,收集因膝骨关节炎行全膝关节置换术的膝内翻患者78例,男17例,女61例;年龄41-85岁,平均68.1岁。体重指数采用普通成年人体重指数(bodymassindex,BMI)的分类标准分为3组:正常组,BMI〈24.0,男3例,女11例,14例28膝,平均年龄(69.5±4.7)岁;超重组,24.0≤BMI〈28.0,男4例,女25例,共29例58膝,平均年龄(66.4±7.9)岁;肥胖组,BMI≥28.0,男10例,女25例,共35例70膝,平均年龄(69.1±8.3)岁。采用躯体x线测量系统测量平卧位和负重位的双下肢力线角度。结果:正常组与超重组患者,平卧位及负重住下肢力线膝内翻角度差异均无统计学意义。肥胖组平卧位膝内翻角度与其他两组差异无统计学意义,负重位膝内翻角度与其他两组差异有统计学意义。体重指数与平卧位和负重位膝内翻角无明显相关性。3组负重位膝内翻角度均大于平卧位。结论:肥胖骨关节炎患者负重位时膝内翻角度增大,提示肥胖是导致下肢力线内翻角度增大的一个重要因素。

关 键 词:骨关节炎  体重  膝关节  力学  病例对照研究

Abstract:Objective:To investigate the relationship between body mass index and lower limb alignment of patients with knee osteoarthritis.Methods:From July 2008 to June 2010,78 patients who suffered from severe knee osteoarthritis were treated with total knee replacement,including 17 males and 61 females,ranging from 41 to 85 years old,with an average age of 68.1 years.The Chinese average adult body mass index(BMI) classification standard was used to classify the patients into three groups:normal group,BMI<24.0,inclu...
