MOON Shoulder Instability-Cohort of Patients Undergoing Operative Treatment.

Running, not enrolling

Conditions studied: Other Instability, Shoulder, Dislocations, Subluxations, Recurrent Dislocation of Shoulder Region

In brief

This project will be a multi-center, prospective longitudinal cohort for all patients undergoing primary shoulder instability surgery, excluding isolated SLAP repairs. We will be looking for risk factors for recurrent instability, revision surgery, and poor outcomes. Patients will be asked to complete the RAND-36, ASES, Shoulder Activity, EQ-5D and WOSI outcome measures, as well as demographic and socioeconomic information. Surgeons will complete a form after surgery with information on radiographic findings, physical exam, surgical findings, and the repair. Patients will wear a sling post-operatively, and follow standardized rehabilitation protocols, including physical therapy. Patients will be sent outcome questionnaires at 2, 6, 10, and 20 years after surgery.
