Abstract: The choice of anterior cruciate ligament reconstruction graft and the histological outcome of the reconstructed graft have been an important research topic in the field of anterior cruciate ligament repair and reconstruction. Anterior cruciate ligament reconstruction is widely used in clinical applications, including autograft, allograft, xenograft, biomaterial, artificial material and tissue engineering graft. Through clinical trials, this paper evaluates knee joint stability and functional recovery during rehabilitation of patients undergoing anterior cruciate ligament reconstruction using different rehabilitation programs. In order to reveal the role of functional training in knee rehabilitation. Fifty-two patients undergoing arthroscopic anterior cruciate ligament reconstruction were randomly divided into a traditional rehabilitation group, a progressive muscle training group, and a functional rehabilitation group. Different rehabilitation intervention programs were given. Before, 6 months, 12 months, and 18 months postoperatively, through an analysis of functional movement analysis, core stability assessment, knee mobility (ROM), knee stability and other rehabilitation indicators, knee joint stability and functional recovery were evaluated after ligament injury and reconstruction. Statistical analysis of the results. The results showed that there was no significant difference between the three groups before surgery (P > 0.05). The test results were significantly different between the postoperative and preoperative groups (p < 0.01). Functional rehabilitation training can be efficient and effective, and safely improve the patient's postoperative muscle strength, joint mobility, joint stability, and other capabilities. In particular, it has obvious advantages in restoring the athletic ability of the affected knee joint, improving rehabilitation efficiency, and shortening the rehabilitation cycle.
