Knee osteoarthritis is a common condition in various orthopedic clinics and hospitals. The aim of this study was to investigate the effects of unilateral total knee arthroplasty (TKA) application on short and long-term spatiotemporal gait parameters, maximum plantar pressure (MPP), and functional status in patients with knee osteoarthritis.
What is the change process in spatiotemporal parameters without any intervention before and after TKA surgery?
This study is a prospective and cross-sectional study. Participants were assessed preoperatively at the 1st week (Pre1W), postoperative 1st month (Post1M) and 6th month (Post6M). Spatiotemporal parameters and MMP were assessed using the Win Track platform (Medicapteurs Technology, France) and functional states were assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and the Lequesne Index.
Significant improvements were found in the WOMAC and Lequesne Index values in the Post1M and Post6M periods compared to the preoperative period. However, the improvement in WOMAC and Lequesne Index scores in the Post6M period was significant compared to the scores in the Post1M period (p < 0.01). Spatiotemporal parameters deteriorated in the Post1M period, while improvements were observed in the Post6M period. We observed that patients had worse gait parameters in the near postoperative period than before surgery. It was the period with the greatest improvements in long-term outcomes.
In the light of our study results, we think that early gait disturbances in patients who underwent direct TKA may be caused by physiological processes. Therefore, we believe that there is no need for any intervention for gait disorders that occur in the early postoperative period.
膝关节骨关节炎在各种骨科诊所和医院中较为常见。本研究旨在探讨单侧全膝关节置换术（TKA）应用对膝关节骨关节炎患者短期和长期时空步态参数、最大足底压力（MPP）和功能状态的影响。
在 TKA 手术前后没有任何干预的情况下，时空参数的变化过程是怎样的？
这是一项前瞻性的横断面研究。参与者在术前第 1 周（Pre1W）、术后第 1 个月（Post1M）和第 6 个月（Post6M）进行评估。使用 WinTrack 平台（法国 Medicapteurs Technology）评估时空参数和最大足底压力，使用 Western Ontario and McMaster Universities Arthritis Index（WOMAC）和 Lequesne 指数评估功能状态。
与术前相比，Post1M 和 Post6M 期间 WOMAC 和 Lequesne 指数值显著改善。然而，与 Post1M 期间的评分相比，Post6M 期间 WOMAC 和 Lequesne 指数评分的改善更为显著（p<0.01）。时空参数在 Post1M 期间恶化，而在 Post6M 期间有所改善。我们观察到患者在术后近期的步态参数比术前更差。这是长期结果改善最大的时期。
根据我们的研究结果，我们认为直接 TKA 患者术后早期的步态障碍可能是由生理过程引起的。因此，我们认为在术后早期出现的步态障碍不需要任何干预。
