【摘要】：目的：目前大部分研究以TKA后关节活动功能和膝关节假体长期存活率作为判断全膝关节置换术(TKA)是否成功的主要标准,而尚无有关TKA对患者维持躯体平衡性能力影响的研究报道。本研究中探讨TKA对膝骨关节炎(0A)患者躯体静态平衡性(body balance)的影响,并分析患者躯体静态平衡性的变化与术后膝关节功能恢复情况是否存在相关性。方法：对2011年1月至2013年12月在我院骨科中心关节外科行单侧TKA的膝0A患者21例(右侧12例,左侧9例)进行站立平衡试验,在单位时间内用重心测量仪连续测量躯体重心位置(GCP)。对GCP在单位时间内的横轴方向偏移(ML-X range)、纵轴方向偏移(AP-Y range)以及GCP漂移轨迹(LG)进行量化分析,探讨GCP的ML-X range、AP-Y range以及LG变化程度与TKA后患者膝关节恢复情况之间的相关性。结果：两组患者经TKA后GCP在横轴方向上的平均位置由初始位置逐渐向术侧方向转移,且其较术前时的转移程度和患者LG较术前时变化程度均与同一时期膝关节功能较术前时水平恢复情况呈相关性,而GCP在纵轴方向上的转移与膝关节功能恢复情况无明显相关性。结论：患者行单侧TKA后,维持躯体平衡能力逐渐提高,且与膝关节功能恢复情况随术后时间呈线性相关。
[Abstract]:Objective: to evaluate the success of total knee arthroplasty (TKA) by using TKA and long-term survival rate of knee prosthesis as the main criteria. However, there is no study on the effect of TKA on the ability of maintaining somatic balance. The purpose of this study was to investigate the effect of TKA on the body balance in patients with knee osteoarthritis (Osteoarthritis), and to analyze the correlation between the changes of somatic static balance and the recovery of knee joint function after operation. Methods: from January 2011 to December 2013, 21 cases (12 right and 9 left) of knee 0A treated with unilateral TKA in our orthopedic central joint surgery department were tested by standing balance test. The position of body center of gravity was continuously measured with a barycenter meter in unit time. The horizontal axis shift (ML-X range), longitudinal axis shift (AP-Y range) and GCP drift trajectory (LGG) of GCP in unit time were quantitatively analyzed, and the correlation between the ML-X range of GCP and the degree of LG change and the recovery of knee joint after TKA was discussed. Results: after TKA, the average position of GCP in the axial direction gradually shifted from the initial position to the operative side. The degree of metastasis and the change of LG were correlated with the recovery of knee joint function in the same period, but there was no significant correlation between the transfer of GCP in the axial direction and the recovery of knee joint function. Conclusion: after unilateral TKA, the ability of maintaining somatic balance was gradually improved, and the recovery of knee joint function was linearly correlated with postoperative time.
