Comparative analysis of modified double-row suture bridge technique versus traditional single-row repair for massive rotator cuff tears with preserved muscle quality (Goutallier stage < 2): a retrospective cohort study

For patients with MRCTs and preserved muscle quality (Goutallier stage < 2), the MDR-SB technique demonstrates superior 12-month structural integrity, more favorable functional recovery trajectories throughout the postoperative period, and a distinct complication profile characterized by superior strength restoration and manageable transient stiffness compared to SR repair.
