Comparing Open and Arthroscopic Surgeries for Shoulder Instability with Moderate Glenoid Bone Loss in Military and Civilian Patients

What this Trial Is About

Researchers are evaluating the outcomes of common surgeries for patients with acute or recurrent anterior shoulder instability who have subcritical bone loss of 10-20%. The study focuses on military personnel and civilians aged 17 to 50 who have experienced traumatic anterior shoulder dislocation. The goal is to understand how different surgical options affect recovery, return to work, sports, and physical function over time. The study compares three surgical procedures arthroscopic Bankart repair with remplissage of a Hill-Sachs lesion, open Bankart repair, and the Latarjet procedure. All participants will receive post-operative rehabilitation tailored to their surgery. The choice of surgery is made jointly by the patient and surgeon. Participants will be followed for 24 months to track outcomes. Participants will undergo imaging scans such as CT or 3D-MRI to measure bone loss and confirm eligibility. Researchers will collect data at multiple time points up to two years after surgery, including patient-reported physical function scores, time to return to pre-injury activities, and any recurrent instability or re-injury events. Additional assessments include range of motion, muscle strength, functional tests, pain, medication use, and quality of life measures. This extensive monitoring aims to identify factors that influence recovery and long-term success.
