Evaluation of the Effects of Home-based Functional Exercise on Patients With ACL

Study Overview
=================
Brief Summary
-----------------
This study will evaluate the effect of home-based functional exercise on patients with anterior cruciate ligament rupture reconstruction based on the health belief model. About 360 participants will be randomly allocated into two groups. One group will randomized to receive precautions and rehabilitation progress reminders and other news by optimized WeChat applet regularly, while the other group will randomized to receive the rehabilitation exercise guidance during routine discharge.

Detailed Description
-----------------
With the development of national fitness and sports, the incidence of anterior cruciate ligament (ACL) injuries has increased. ACL reconstruction is the best treatment for ACL injury. The success rate of surgery is high, but the patient still needs to rehabilitate after surgery, otherwise it is difficult to fully recover knee function. However, the rehabilitation medical resources in China are obviously insufficient. Patients who have undergone ACL reconstruction usually return home to work according to the rehabilitation plan. However, the adherence is still poor, and it is difficult to achieve the expected effect. The WeChat public account and its affiliated applets have been widely used in different health fields. The Health Belief Model (HBM) is a guiding theory commonly used in health education to guide patients for behavioral changes. This study aims to use the WeChat small program to explore the effects of optimized the existing Peking University Third Hospital Sports Medicine WeChat small program by using HBM to improve the adherence of patients with home-based functional exercise after ACL injury reconstruction.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| qualified rate of knee joint activity | Knee joint activity reaches 125 degrees or above is judged to be qualified. Qualified rate is equal to the number of people who meet the standard divided by the total number in each group. | 6 weeks after surgery | 
| qualified rate of knee joint activity | Knee joint activity reaches 125 degrees or above is judged to be qualified. Qualified rate is equal to the number of people who meet the standard divided by the total number in each group. | 2 weeks after surgery | 
| qualified rate of knee joint activity | Knee joint activity reaches 125 degrees or above is judged to be qualified. Qualified rate is equal to the number of people who meet the standard divided by the total number in each group. | 12 weeks after surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Visual Analogue Scale | The Visual Analog or Analogue Scale (VAS) is designed to present to the respondent a rating scale with minimum constraints. Respondents mark the location on the 10-centimeter line corresponding to the amount of pain they experienced. This gives them the greatest freedom to choose their pain's exact intensity. It also gives the maximum opportunity for each respondent to express a personal response style. VAS data of this type is recorded as the number of millimeters from the left of the line with the range 0-100. Aitken, R. C. B. (1969). Measurement of feelings using visual analogue scales.

| SF-12 scale | The SF-12 scale is a simplified version of the Universal Concise Health-Related Quality of Life Scale SF-36 scale developed by the Boston Institute of Health Education.
