Anterior cruciate ligament reconstruction (ACLR) is the preferred treatment to restore the original activity level of patients. The single-leg drop jump can not only identify high-risk exercise strategies, but also provide a standard for the rehabilitation process of ACLR. In this review, a combined search of ‘single-leg drop jump’ ‘anterior cruciate ligament reconstruction’ ‘biomechanics’ was conducted through CNKI, PubMed, Embase and other databases, and the biomechanical changes of single-leg drop jump after ACLR and related intervention methods are summarized. The research findings will help adjust rehabilitation strategies after ACLR and avoid high-risk actions with secondary injuries. The analysis of single-leg drop jump after ACLR can guide clinicians and rehabilitation therapists to formulate and adjust rehabilitation treatment plan, improve the postoperative rehabilitation efficiency of ACLR , and help patients return to exercise early.
