Background: When dealing with anterior cruciate ligament (ACL) tears, anatomic single-bundle reconstruction with remnant-preserving method offers numerous advantages, including enhanced revascularization and graft ligamentization, prevention of synovial fluid bath to the tunnels, and enhanced bone tendon healing . Objective: assess the efficacy and outcome of anatomic single-bundle reconstruction with remnant-augmenting technique in patients with an ACL tear. Patients and Methods: At the Orthopedic Departments of Zagazig University hospital, 18 patients with complete ACL damage were studied in prospective cohort research. The study was carried out from 2-11/2021. All patients received an anatomic single-bundle reconstruction using a remnant-preserving approach, and all patients were periodically monitored clinically and radiographically for a week, then every 2, 4, 6, and 12 weeks after the index procedure. Results: 33.3% of studied patients were complicated; superficial Infection was in 27.8%, Failure was just in one case and stiffness 2 cases only there were no other complications. VAS was significantly higher among complicated cases at the post but Lysholm knee score was significantly lower at pre and post and regard IKDS was significantly lower at post only. Conclusion: Patients with ACL tears benefit more from anatomic single-bundle restoration using the remnant-augmenting method, which improves proprioceptive functions, stability, and healing of the graft.
