An observational study in Other Instability, Shoulder, Dislocations and Subluxations, sponsored by Carolyn M Hettrich. Active, not recruiting at 11 sites in United States. Open to participants aged 12 Years to 99 Years. Per ClinicalTrials.gov, last updated 2026-04-08.

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.
The objective of this prospective multicenter cohort study of patients undergoing surgery for glenohumeral instability is to identify the outcomes, and more importantly, the previously unknown predictors of sports function, activity level, general health, recurrent instability symptoms, and surgical failures following surgery. Patient information at the time of the surgery (demographics, validated outcome measures), in addition to the physical exam findings, shoulder pathology at the time of surgery, and surgical treatment will be obtained. The validated outcome instruments are American Shoulder and Elbow Surgeons Score, Western Ontario Shoulder Instability, Kerlan Jobe Overhand Athlete Score, Shoulder Activity Score, and RAND-36. Post-operative physical exam data will be obtained at 6 months after surgery. Patient reported outcomes will be repeated at 2, 6, 10, and 20 years post-operatively. Our multivariable analysis will identify which of the many factors related to the injury, intra-operative treatment, postoperative care, physical patient characteristics, and behavioral patient characteristics contribute to recurrence and poor outcome.
