Investigating the effects of shoulder surgery on stability and proprioception

The Effect of Arthroscopic Bankart Repair on Anterior-posterior Glenohumeral Translation and Shoulder Proprioception in Patients With Traumatic Anterior Shoulder Instability: a Prospective Cohort Study

This study is testing if shoulder surgery can improve stability and movement sense in people with shoulder instability from trauma.

Quick facts

• Study type: Observational
• Enrollment: 30 (estimated)
• Ages: 18 Years to 40 Years

What this trial studies

This study aims to evaluate the impact of arthroscopic Bankart repair on shoulder biomechanics and proprioception in patients suffering from traumatic anterior shoulder instability. It will utilize non-invasive examination methods to assess changes in anterior-posterior glenohumeral translation and scapular rotations before and after surgery at six and twelve months. The study will also gather patient-reported outcomes to understand the overall effectiveness of the intervention. The goal is to determine if the surgical procedure restores shoulder function to levels comparable to the non-injured shoulder.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 18-40 with unilateral traumatic anterior shoulder instability scheduled for arthroscopic Bankart repair.

Not a fit: Patients with bilateral shoulder instability or other specific shoulder injuries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and rehabilitation strategies for patients with shoulder instability.

How similar studies have performed: Previous studies have shown promising results with similar surgical approaches, indicating potential for success in this investigation.
