Modified arthroscopic suture-button Latarjet procedure for recurrent anterior shoulder instability: 9-Year minimum follow-up

To evaluate the efficacy of the modified arthroscopic suture-button (MASB) Latarjet procedure with at least 9 years of follow-up and remodelling of the coracoid grafts (CGs). Patients who underwent the MASB Latarjet procedure between February 2013 and February 2016 were retrospectively reviewed. The clinical outcomes, complications, union and remodelling of the CGs and glenohumeral degeneration were assessed postoperatively in a follow-up period of at least 9 years. A total of 106 patients were enroled with a mean follow-up of 110.3&#x2009;&#xb1;&#x2009;4.2 months. Significant improvements were observed in visual analogue scale (VAS) pain scores during motion, the American Shoulder and Elbow Surgeons (ASES), Rowe and Walch-Duplay scores (p&#x2009;<&#x2009;0.001), with no significant range of motion (ROM) limitations at final follow-up. The complication rate was 8.5%, including two cases of instability, one requiring revision surgery. In the en-face sagittal view, 86.8% of grafts were excellently or well-positioned, and 89.6% were flush with the glenoid in the axial view. CG-glenoid union occurred in 99.1% of cases, restoring 99.5&#x2009;&#xb1;&#x2009;1.4% of the PFC, with no evident arthropathy at final follow-up. The MASB Latarjet provided durable shoulder stability and high patient satisfaction at 9-year follow-up, with low complications, minimal ROM loss and no evident glenohumeral degeneration. Level IV, case series.
