Abstract

Abstract
Background: In spite of the considerable research focused on ACL reconstruction, the increased risk of early knee osteoarthritis and the presence of rotational instability post-surgery have not been fully investigated yet. As a result, controversy remains regarding the best technique for recon-struction; thus, it is still the subject of extensive research.
Aim of the Work: To assess the radiological and clinical outcomes of arthroscopic single bundle ACL reconstruction using the transtibial or the anteromedial portal (two tunnels) technique for drilling the femoral tunnel in nonprofessional athletes.
Patients and Methods: It is a prospective comparative study including forty patients with a torn ACL underwent arthroscopic reconstruction of the ACL, twenty patients had ACL reconstruction by transtibial (TT) technique and twenty patients had ACL reconstruction by Anteromedial Portal (AMP) technique using hamstring tendons as autograft for all the patients.
Results: All the patients were followed-up clinically with IKDC scores, Lysholm score, Tegner activity score and Radi-ologically for assessment of tunnel widening and femoral tunnel position using plain X-ray and CT at 3, 6 and 12 months post-operatively.
Conclusion: The AMP independent femoral tunnel drilling technique achieved a more horizontal and anatomic femoral tunnel, but the AMP technique has no clinical superiority compared to the TT technique in ACL reconstruction in nonprofessional athletes as reported by these short-term follow-up results.
