Abstract：Objective To explore the effectiveness of the continuous passive motion method after primary total knee ar-throplasty(TKA)during the early recovery period.Methods One hundred patients who underwent total knee arthroplasty(TKA)in the Department of Orthopedics of Subei People's Hospital in Jiangsu Province from January 2023 to January 2024 were select-ed as the research subjects.According to the rehabilitation plan,they were divided into the cold compress alone treatment group(control group,n=50)and the combined treatment group of cold compress and continuous passive motion(experimental group,n=50).In-hospital rehabilitation training was carried out to evaluate the self-efficacy of rehabilitation exercise,the changes in the flexion angle,knee joint flexibility,and Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)pain score of patients before and after surgery.Additionally,the improvement in the clinical characteristics and pain scores of patients after the cold compress alone treatment and the combined treatment of cold compress and continuous passive motion treatment was as-sessed.Results The self-efficacy levels of rehabilitation exercise were different among TKA patients of different ages(P<0.05),and the self-efficacy level of exercise was relatively low in patients aged≥80 years.The postoperative flexion angle of the joint,knee joint flexibility,and WOMAC pain score significantly improved compared with those before the surgery(P<0.05 for all).Adding continuous passive motion to the cold compress alone treatment did not significantly improve the knee flexion angle and WOMAC pain score(P>0.05 for all),but could effectively improve the joint flexibility(P<0.05).Conclusion Age is a factor affecting the self-efficacy of patients'exercise.Adding continuous passive motion after TKA surgery helps to restore the range of joint motion and improve the flexibility of the knee joint.
