Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to compare the knee function between patients with and without preoperative exercise habits at 1, 2 and 5 years after ACL surgery, and further analyze the effect of maintaining exercise habits on knee function and recurrence rate

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Objective:

1. To compare the knee function between active and inactive patients at 1, 2, and 5 years after ACL surgery.
2. To investigate the difference of knee function and recurrence rate between patients with and without postoperative exercise habit.

Methods: This is a single-center, controlled follow-up cohort study. Inclusion criteria included patients aged 18-45 years with confirmed ACL injury who were scheduled to undergo ACL reconstruction surgery. Exercise habits were recorded before operation, and knee joint function and exercise level were evaluated by questionnaires. All patients received standardized ACL reconstruction surgery and rehabilitation program after surgery. In prospective cohort study, 121 patients were divided into running group and non-running group according to their preoperative exercise habits. At 3 months after surgery, running was included in the rehabilitation program, and the patients were further divided into postoperative running and non-running groups and followed up for one year.In Postoperative cohort study, follow-up was collected and evaluated at 1 year, 2 years and 5 years, including knee function, exercise level and recurrence. The study was divided into four groups: preoperative running group , preoperative non-running group , preoperative and postoperative running group and preoperative non-running and postoperative running group to analyze the effects of preoperative and postoperative exercise habits on knee joint function and recurrence rate. The results of this study will help to deepen the understanding of the impact of preoperative exercise habits and postoperative exercise maintenance on knee function and recurrence rate after ACL reconstruction, and then provide guidance for clinical practice, optimize postoperative rehabilitation programs, and ultimately improve the quality of life of patients.
