Comparison Between Combined ALLR With Single Bundle and Double Bundle Anterior Cruciate Ligament Reconstruction
Sponsor: Chang Gung Memorial Hospital
Summary
The goal of this clinical trial is to test and compare different surgical techniques in patients with anterior cruciate ligament (ACL) injuries. The main questions it aims to answer are: * What are the optimal criteria for selecting between single-bundle ACL reconstruction combined with anterolateral ligament (ALL) reconstruction versus double-bundle ACL reconstruction combined with ALL reconstruction? * How do these two surgical techniques compare in terms of post-operative knee stability, functional outcomes, and reducing re-tear rates? Participants will: * Undergo pre-operative MRI imaging, ligament stability testing, and motion analysis evaluations * Be randomly assigned to either: * Single-bundle ACL + ALL reconstruction * Double-bundle ACL + ALL reconstruction * Receive the assigned surgical procedure * Participate in post-operative follow-ups, ligament stability testing, and motion analysis at 6 months and 1 year Researchers will compare the single-bundle ACL + ALL group and the double-bundle ACL + ALL group to see if one technique demonstrates superior knee stability, functional outcomes (e.g. return to sport ability), and lower ACL re-tear rates.

Interventions
Single-bundle ACL combined anterolateral ligament reconstruction
Single-Bundle ACL + ALL Reconstruction Group: Patients in this group will undergo reconstruction of the anterior cruciate ligament (ACL) using a single-bundle graft technique. In addition, they will have the anterolateral ligament (ALL) reconstructed using a portion of the same graft material. The single ACL bundle is typically positioned to replicate the anatomic footprint of the native ACL. For the ALL reconstruction, a commonly used technique is the Sonnery-Cottet ALL reconstruction using a gracilis tendon graft. This combines an intra-articular ACL reconstruction with an extra-articular lateral tenodesis to improve rotational instability.
Double-bundle ACL combined anterolateral ligament reconstruction
Double-Bundle ACL + ALL Reconstruction Group: Patients in this group will undergo anatomic double-bundle ACL reconstruction using two graft bundles to more anatomically replicate the native ACL\'s anteromedial and posterolateral bundles. Like the single-bundle group, they will also have supplemental ALL reconstruction performed using a portion of the graft material. The double-bundle ACL reconstruction aims to better restore the ACL\'s complex anatomic footprint and bundles\' tension patterns.
