Study summary

Based on the home rehabilitation exercise of patients undergoing ACL reconstruction, the existing WeChat applet of sports medicine of the Third Hospital of Beijing Medical University is optimized to be used as a health education tool to guide patients undergoing home rehabilitation exercise after ACL reconstruction.

Read the detailed description

With the development of national fitness and sports, the incidence of ACL injury is increasing year by year. ACL reconstruction is the best way to treat ACL injuries, and the success rate of the operation is high, but patients still need to recover after surgery, otherwise, it will be difficult to fully restore knee joint function. However, my country's rehabilitation medical resources are obviously insufficient. After discharge from the hospital, ACL reconstruction patients usually go home and exercise at home according to the rehabilitation plan formulated by the surgeon or rehabilitation physician. However, compliance is still poor, and rehabilitation is relatively difficult to achieve the expected results, which affects the lives of patients quality. The WeChat official account and its affiliated mini-programs have been widely used in different health fields as a means of health communication. The health belief model is a guiding theory commonly used in the field of health education to guide patients to make behavior changes. This study intends to use the functional advantages of the WeChat applet to explore the optimization of the existing Peking University Third Hospital Sports Medicine WeChat applet based on the health belief model and to use the postoperative rehabilitation of patients undergoing ACL injury reconstruction as a pilot to evaluate the optimized The WeChat Mini Program can improve the intervention effect of patients' home functional exercise compliance after ACL injury reconstruction, to provide effective health education for more extensive sports medicine-related home functional exercises, improve their rehabilitation effects and quality of life, and better To ensure the efficacy of surgery.
