全膝关节置换术后关节活动范围的影响因素分析

An analysis of influence factors on range of knee motion after total knee replacement

目的:探讨全膝关节置换术后关节活动范围的影响因素,从而制订相应的康复治疗方案。方法:21例接受全膝关节置换术的患者入组,采用HSS评分法对所有患者进行术前膝关节功能评估,应用关节量角器对膝关节进行关节活动范围测定。采用Pearson相关分析法对术前各因素与术后1、2周及出院时膝关节活动范围进行相关分析。采用独立t检验对术后1、2周及出院时膝关节活动范围进行比较。结果:术前HSS总分、术前关节疼痛、术前膝关节功能、术前膝关节活动和术前屈膝畸形与术后1周膝关节活动范围成正相关,相关系数分别为0.546、0.430、0.423、0.539和0.403,P<0.05。术前所有评估因素除年龄外与术后2周和出院时关节活动度无相关。结论:术前关节疼痛、膝关节功能、膝关节活动和术前屈膝畸形与术后膝关节活动范围相关。

Objective:To investigate the influence factors on range of knee motion after surgery, therefore, to design a appropriate rehabilitation program.Method: 21 patients who received the total knee replacement were involved in this study. They were assessed using the HSS scale, knee function, and range of knee motion before surgery. Pearson correlation was used to analyze the factors measured before surgery and post-operative knee motion at week 1,2. Independent t-test was used to compare the range of knee motion at different time interval. Result:The pre-operative HSS scale, knee pain, knee function, range of knee motion and deformity of knee flexion had a positive correlation with range of knee motion post-surgery.The correlation value was 0.546?0.430?0.423?0.539 and 0.403 respectively(P<0.05).Conclusion:Knee pain,knee function,knee flexion deformity have a positive correlation with knee motion after surgery.
