Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals under 20 years old with recurrent anterior glenohumeral dislocations and evidence of bone loss on imaging.
✕Probably not a fit
Patients with uncontrolled diabetes, prior shoulder surgery, or other specific exclusions such as severe systemic illness or cancer may not benefit from this study.

What this trial studies
This pilot trial aims to evaluate the feasibility of comparing two surgical techniques, arthroscopic Bankart repair and arthroscopic anatomic glenoid reconstruction, for treating recurrent shoulder dislocations. The study will assess the ability to recruit patients across multiple sites and adherence to the study protocol over a 24-month follow-up period. While the primary focus is on feasibility, the trial will also gather data on dislocation rates and functional outcomes to inform a larger definitive trial in the future.
Why it matters
Potential benefit: If successful, this study could lead to improved surgical options and outcomes for patients suffering from recurrent shoulder dislocations.
How similar studies have gone: Previous studies have shown that surgical management of shoulder instability can significantly reduce recurrence rates, indicating potential success for this approach.
