Abstract:
Objective:To explore the mediating effect of psychological resilience on self-efficacy and knee functional recovery of patients after artificial total knee arthroplasty, and to provide theoretical basis for promoting functional recovery after artificial total knee arthroplasty.Methods:This was a cross-sectional survey study. A total of 250 patients undergoing artificial total knee arthroplasty at the Orthopedics Department of Beijing Jishuitan Hospital Affiliated to Capital Medical University were set as the research objects from September 2021 to March 2022, self-designed demographic questionnaire, General Self-Efficacy Scale (GSES), Connor Davidson Resilience Scale (CD-RISC) and Hospital for Special Surgery (HSS) scale were used to evaluate postoperative self-efficacy, psychological reselience and knee function.Results:A total of 225 valid questionnaires were recovered. The GSES score, CD-RISC score and knee function score of 225 patients were (26.45 ± 3.75), (68.01 ± 2.85) and (71.76 ± 4.53) points, respectively. Psychological resilience was positively correlated with self-efficacy and knee function score ( r=0.535, 0.675, both P<0.05), and self-efficacy was positively correlated with knee function score ( r=0.688, both P<0.05). Stratified regression analysis in showed that self-efficacy, tenacity, strength, optimism, and psychological resilience were included in the equation, adjusted for R2=0.812, indicating good fit of the model. The mediation model showed that psychological resilience was partially mediated between self-efficacy and functional recovery, with its mediation effects accounting for 25.49% of the total effect. Conclusions:The recovery of knee function in patients after artificial total knee arthroplasty is at a moderate level, and improving psychological resilience and self-efficacy may probably promote the recovery of knee function.
