What this trial studies

This observational study aims to evaluate the safety and efficacy of autologous microfragmented lipoaspirate tissue in enhancing the outcomes of arthroscopic rotator cuff repair. It focuses on patients with full-thickness supraspinatus and infraspinatus tendon tears who are undergoing surgery. The study will assess clinical outcomes using the Constant-Murley score at least five years post-surgery, comparing results between those receiving the fat tissue injection and those who do not. Various assessments, including MRI and strength measurements, will be utilized to gather comprehensive data on recovery and function.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with full-thickness supraspinatus and infraspinatus tendon tears requiring arthroscopic repair.

Not a fit: Patients with partial or massive rotator cuff tears, significant muscle atrophy, or other shoulder instabilities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved healing and reduced retear rates in rotator cuff repairs.

How similar studies have performed: While the use of autologous fat tissue in surgical procedures is gaining interest, this specific approach in rotator cuff repair is relatively novel and not extensively tested.
