Objective To explore the trajectory and influencing factors of joint awareness after total knee arthroplasty.Methods With the method for convenience sampling,patients who met the standards for total knee arthroplasty from July 2021 to March 2022 were selected.General information,severity of osteoarthritis,anxiety and depression,and self-efficacy were investigated before surgery(T0).Joint awareness was investigated at 1 month(T1),3 months(T2),and 6 months(T3)after surgery,respectively.Latent growth curve model was used to describe the overall trend of joint awareness;latent class growth model was used to analyze latent subgroups;logistic regression analysis was used to determine the impact of related variables on the trajectory of joint awareness.Results The scores of joint awareness were(32.70±5.80),(47.67±4.67)and(61.53±7.81)respectively at T1 to T3,and joint awareness showed an increasing trend(P＜0.001).The trajectory of joint awareness was divided into 2 potential subgroups:the rapid growth group(61.83％)and the slow growth group(38.17％).Age,BMI,other chronic diseases or not,years of osteoarthritis,severity of osteoarthritis,anxiety,depression,and self-efficacy affected the trend of joint awareness(all P＜0.05).Conclusion Joint awareness showed a linear growth trend with the postoperative time,and there were 2 potential subgroups in the trajectory.Medical workers could develop corresponding interventions based on the influencing factors to improve patients'postoperative awareness of artificial joints.
