ABSTRACT
Introduction:
Anterior Cruciate Ligament (ACL) reconstruction in patients with a more than one-year rupture is associated with anteromedial rotator instability (AMRI). Additional procedures to correct developmental AMRI have demonstrated improved outcomes compared to isolated ACL reconstruction. Purpose: ACL reconstruction and Medial Collateral Ligament (MCL) augmentation will restore the AMRI.
Aim:
In this study, we present a unique approach to treating chronic AMRI. We observed the development of chronic AMRI in patients who had neglected their ACL rupture.
Material and methods:
In this prospective single-arm case series, 32 patients with chronic AMRI (more than 1 year since injury) were included. A Bone-Tendon-Bone BTB graft for ACL reconstruction and semitendinosus tendon augmentation of the MCL were performed, and a 2-year follow-up was conducted to assess knee stability and Range of Motion (ROM).
Results and discussion:
At the end of the follow-up, most patients showed a significant improvement in their International Knee Documentation Committee (IKDC) scores, with knee stability restored to normal in 90.7% of cases. These findings demonstrate substantial post-operative improvement following the combined ACL reconstruction and MCL augmentation.
Conclusions:
The BTB reconstruction of the ACL with an augmented MCL was associated with significant improvement in knee stability and functional scores in patients with chronic AMRI. This technique requires minimal additional action compared to a simple BTB technique, making it a feasible option for orthopedic surgeons.
