Comparing two methods for repairing rotator cuff tears

Arthroscopic Rotator Cuff Repair Utilizing Mechanical Bone Debridement Versus Coblation Debridement: A Prospective Randomized Double Blind Controlled Trial

NA · University of Calgary · NCT05084781

This study is testing whether a new way to clean up tissue during rotator cuff surgery helps patients recover better than the traditional method.

What this trial studies

This clinical trial is a randomized controlled trial that compares the effectiveness of coblation debridement versus mechanical debridement in patients undergoing surgical repair for full thickness rotator cuff tears. Participants, aged 18 and older, will be randomly assigned to one of the two treatment groups after confirming their eligibility through pre-operative assessments. The study includes a standard post-operative rehabilitation program and follow-up evaluations at 3, 6, 12, and 24 months to assess recovery and outcomes. The goal is to determine which debridement method leads to better patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with a repairable full thickness rotator cuff tear who have not responded to conservative treatments for more than 3 months.

Not a fit: Patients with previous rotator cuff repair surgery, partial thickness tears, or irreparable tears will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and recovery for patients with rotator cuff tears.

How similar studies have performed: Previous studies have shown varying success with different debridement techniques, making this approach both relevant and necessary for further exploration.
