How does kinesiophobia affect short- and long-term gait parameters in individuals with total knee arthroplasty surgery?

Delays in weight transfer due to various fears after Total knee arthroplasty (TKA) surgery negatively affect recovery. Therefore, the presence of kinesiophobia is essential for the success of the treatment. This study was planned to investigate the effects of kinesiophobia on Spatio-temporal parameters in patients who underwent unilateral TKA surgery. This study was a prospective and cross-sectional study. Seventy patients with TKA were assessed preoperatively in the 1st week (Pre1W) and post- operatively in the 3rd month (Post3M) and 12th month (Post12M). Spatiotemporal parameters were assessed using the Win-Track platform (Medicapteurs Technology, France). The Tampa kinesiophobia scale and Lequesne index were evaluated in all individuals. A significant relationship was found between the Pre1W, Post3M, and Post12M periods and Lequesne Index scores (p<0.01), and this relationship was in favor of improvement. In the Post3M period, kinesiophobia increased compared to the Pre1W period, and kinesiophobia decreased effectively in the Post12M period (p<0.01). The effect of kine-siophobia was evident in the first postoperative period. In the correlation analyses between spatiotemporal para- meters and kinesiophobia, significant negative correlations were observed (p<0.01) in the early postoperative period (Post3M). Evaluating the effectiveness of kinesiophobia on Spatio-temporal parameters at different time intervals before and after TKA surgery may be necessary for the treatment process.

BACKGROUND: 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. RESEARCH QUESTION: What is the change process in spatiotemporal parameters without any intervention before and after TKA surgery? METHODS: 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. RESULTS: 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. SIGNIFICANCE: 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.
