Abstract:
Objective To investigate the influencing factors and correlation among kinesiophobia,sar-copenia and fall risk following total knee arthroplasty(TKA).Methods A total of 180 patients with knee os-teoarthritis who underwent TKA in our hospital from July 2021 to June 2024 were selected as the research subjects.The clinical data of patients,including age,gender,disease duration,concomitant chronic diseases and off-bed ambulation time,were recorded.The knee joint function was evaluated using the Hospital for Special Surgery(HSS)score at 1 month after surgery.The Tampa Scale for Kinesiophobia(TSK)was used to assess kinesiophobia at 1 week and 1 month after surgery.The Relative Skeletal Muscle Mass Index(RSMI)was a-dopted to evaluate sarcopenia before surgery and at 1 month after surgery.The Morse Fall Scale(MFS)was employed to assess the risk of falls before surgery and at 1 month after surgery,and the relative risk(RR)was calculated.Results The TSK score and incidence of kinesiophobia at 1 month postoperative were signifi-cantly reduced compared to those at 1 week postoperative(P<0.05).The RSMI value and incidence of sar-copenia at 1 month postoperative were significantly reduced compared to those preoperatively(P<0.05).The MFS score and incidence of high fall risk at 1 month postoperative were significantly reduced compared to those preoperatively(P<0.05),and the RR of fall risk before and after surgery was 5.47.Factors influencing kinesiophobia,sarcopenia,and high fall risk included gender,age,time-to-ambulation,and knee function(P<0.05).The incidence of sarcopenia and high fall risk differed significantly between patients with versus with-out kinesiophobia(P<0.05).A statistically significant difference existed in the incidence of high fall risk be-tween patients with sarcopenia and those without sarcopenia(P<0.05).At 1 month after surgery,RSMI was negatively correlated with TSK score and MFS score(r=-0.62,-0.40;P<0.05),while TSK score was positively correlated with MFS score(r=0.44;P<0.05).Conclusion Kinesiophobia,sarcopenia,and in-creased fall risk may occur after TKA.These outcomes are related to gender,age,time to ambulation,and knee function,with interconnections among these factors.
