摘要
全膝关节置换术是治疗终末期膝关节骨关节炎的有效方法之一,然而,仍有患者在膝关节置换术后表现出步速下降、膝关节不稳定等异常运动学改变。膝关节的运动学对膝关节的运动状态进行了量化描述,有助于更加客观、精确地评估患者术后膝关节的功能。本文主要介绍了全膝关节置换术后患者膝关节的运动学变化及其影响因素。通过文献整理分析发现,尽管患者在全膝关节置换术后步速、步长、膝关节活动度等步态参数较术前改善,但是与正常人相比仍存在一定差距,患者的膝关节运动也受到假体设计、手术方式和对线方法等因素的影响。运动分析系统可用于采集患者术前、术后的运动学数据,分析患者出现术后运动学异常的病理变化机制,为个体化制定术后快速康复方案、提高患者满意度提供理论依据。
Total knee arthroplasty(TKA)is one of the effective procedures in treating terminal stage knee osteoarthritis.However,some patients continue to report abnormal kinematic changes such as decreased step velocity,instability after TKA.The kinematics of the knee quantitatively describe the motion of the knee,which can help better assess the function of the knee more precisely and objectively.This article aimed at introducing kinematic changes of patients’knee and factors that influence patients’kinematics after TKA.According to the documented data,although better gait parameters are achieved after TKA,some defects are still noticed in patients compared to normal people.In addition,patients’kinematics is affected by prosthesis design,operation method,and lower extremity alignment,etc.The pre-and post-operative kinematic data of patients collected by motion analysis system would be helpful in exploring the mechanism of pathological changes in patients with postoperative kinematic abnormalities,thus providing theoretical basis for the guideline of individualized post-operative rapid rehabilitation and improving patients’satisfaction.
