Fat stem cells may speed shoulder tear recovery
NCT ID NCT06505135
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding stem cells from a patient's own fat tissue to standard rotator cuff surgery can improve healing and reduce recovery time. About 30 adults with shoulder tendon tears will receive the stem cell injection during surgery. The goal is to see if this simple, minimally invasive approach leads to better pain relief and shoulder function than surgery alone.
