Ligament Advanced Reinforcement System (LARS) Augmented Repair vs Autograft Reconstruction for Chronic Lateral Ankle Instability: A Retrospective Comparative Study

Listen to this summary

This study aimed to compare the recovery trajectories and functional outcomes of Ligament Advanced Reinforcement System (LARS) augmented repair versus autograft reconstruction in patients with chronic lateral ankle instability over a 24-month period. The findings indicated that while both techniques led to significant improvements in functional outcomes, LARS provided faster early recovery, with notable differences in scores at 1, 3, and 6 months, although these differences diminished by the 12- and 24-month marks. Ultimately, LARS may be preferred for patients seeking quicker functional recovery.
