背景：以往的研究表明膝关节的运动学在步态中影响躯干和骨盆。然而，影响膝关节骨关节炎患者术后步态中躯干运动的因素仍不清楚。OBJECTIVE：通过比较膝关节骨关节炎患者与健康对照组，研究全膝关节置换术（TKA）对步态中躯干运动的影响。膝关节和髋关节屈曲和躯干和骨盆倾斜步态过程中获得使用三维运动分析系统。膝关节活动范围，疼痛，和运动学数据收集术前和术后1年的膝关节骨关节炎patients.Results：膝关节伸展限制和疼痛显着改善术后相比，术前阶段。术前，骨关节炎患者在站立阶段的躯干前倾峰值明显大于对照组。在站立阶段的峰值前躯干倾斜显着小于术后比术前stages.CONCLUSIONS：这些结果表明，全膝关节置换术后，膝关节骨关节炎患者的躯干运动大致等于那些控制，改善临床结果，如膝关节伸展限制和疼痛。
BACKGROUND: Previous studies have indicated that the kinematics of the knee joint affect the trunk and pelvis during gait. However, the factors that influence trunk movement in knee osteoarthritis patients during gait after surgery remain unclear.OBJECTIVE: To examine the effect of total knee arthroplasty (TKA) on trunk movement during gait by comparing knee osteoarthritis patients with healthy controls.METHODS: Fourteen medial knee osteoarthritis patients who underwent initial unilateral TKA and 11 controls participated in this study. Knee and hip joint flexion and trunk and pelvic tilts during gait were acquired using a three-dimensional motion analysis system. Knee joint range of motion, pain, and kinematic data were collected preoperatively and 1 year postoperatively for knee osteoarthritis patients.RESULTS: Knee extension limitation and pain significantly improved postoperatively compared with preoperative stages. Preoperatively, the peak anterior trunk tilt during the stance phase was significantly larger in osteoarthritis patients than in controls. The peak anterior trunk tilt during the stance phase was significantly smaller postoperatively than at preoperative stages.CONCLUSIONS: These results suggest that after TKA, the trunk movements of knee osteoarthritis patients were approximately equal to those of controls, with improvement in clinical outcomes such as knee extension limitation and pain.
