Purpose: To explore the influence of continuous nursing on postoperative rehabilitation of patients undergoing total knee arthroplasty. Methods: 78 patients undergoing total knee arthroplasty were selected and divided into two groups according to the different intervention measures, 39 patients in each group. The control group received routine nursing, while the observation group further received continuous nursing based on WeChat platform. The action capacity, activity of daily living, and incidence of knee stiffness and other complications of the two groups were compared. Results: After continuous nursing, the action capacity and activity of daily living of the observation group were better than those of the control group, and the incidence of knee stiffness was lower than that of the control group, and the differences were statistically significant (P<0.05). Conclusion: Continuous nursing based on WeChat platform can improve the function of knee joint, increase the range of motion of knee joint, improve the activity of daily living, and reduce the occurrence of related complications for the patients undergoing total knee arthroplasty.
