Comparing Latarjet and Anatomic Glenoid Reconstruction Surgeries for Treating Anterior Shoulder Instability with Significant Bone Loss

What this Trial Is About

Anterior shoulder dislocations cause pain, stiffness, and glenoid bone loss, leading to a high risk of recurrence if untreated. This trial compares two surgical treatments, the Latarjet procedure and the Anatomic Glenoid Reconstruction AGR, to evaluate their clinical and radiographic outcomes. The study aims to determine which approach better addresses shoulder instability due to bone loss, focusing on reducing recurrence and complications. The trial involves two procedures the Latarjet, where the coracoid process is transferred and fixed to the glenoid to increase stability, and the AGR, which uses a distal tibia allograft inserted arthroscopically through a special portal to restore the glenoid size. Both surgeries aim to improve shoulder function and reduce instability, but AGR may offer fewer complications and less muscle damage. The study will randomize 68 participants to receive one of these treatments. Participants will be monitored with clinical assessments and imaging over two years. Outcomes include complication rates, recurrent instability, patient-reported function scores, and radiographic measures of muscle volume, graft condition, and glenoid size. Safety and effectiveness will be evaluated through questionnaires and scans at multiple time points. The total study period includes pre-operative assessment and follow-up visits up to two years after surgery.
