膝骨性关节炎合并内翻畸形患者运动特征研究

为研究膝骨性关节炎合并内翻畸形患者术前生物力学群体特征,用于比较患者术前术后步态延续性及进行术后康复指导,本文采集9例患者水平行走和坐立-起身过程的步态,并进行骨肌多体动力学分析。本文研究结果显示,水平行走时试验组下肢运动功能减弱,试验组非手术侧膝关节平均活动范围为22.5°～71.5°,拟置换侧膝关节平均活动范围为24.4°～57.6°,而对照组膝关节平均活动范围为7.2°～62.4°。单侧膝内翻患者完成坐立-起身过程时的下肢地面反作用力对称度介于0.72～0.85,非手术侧下肢起主要支撑作用。双侧膝内翻患者坐立-起身时地面反作用力之和最小。尽管单侧膝内翻患者采用非手术侧下肢过量负载的代偿方...

Summary:为研究膝骨性关节炎合并内翻畸形患者术前生物力学群体特征,用于比较患者术前术后步态延续性及进行术后康复指导,本文采集9例患者水平行走和坐立-起身过程的步态,并进行骨肌多体动力学分析。本文研究结果显示,水平行走时试验组下肢运动功能减弱,试验组非手术侧膝关节平均活动范围为22.5°～71.5°,拟置换侧膝关节平均活动范围为24.4°～57.6°,而对照组膝关节平均活动范围为7.2°～62.4°。单侧膝内翻患者完成坐立-起身过程时的下肢地面反作用力对称度介于0.72～0.85,非手术侧下肢起主要支撑作用。双侧膝内翻患者坐立-起身时地面反作用力之和最小。尽管单侧膝内翻患者采用非手术侧下肢过量负载的代偿方式能完成术后日常活动,但长期过量负载容易增加非手术侧下肢膝关节罹患膝骨性关节炎风险。对膝骨性关节炎合并内翻畸形患者完成日常活动的运动学和生物力学特征进行研究,有助于从生物力学角度理解内翻膝的发病机制,对患者的术前评估、预防和术后恢复具有较强的临床指导意义。
