Bone Marrow Derived Stem Cells for the Treatment of Rotator Cuff Tears

The primary objective is to determine whether adjunct treatment using bone marrow aspirate concentrate (BMAC) in conjunction with arthroscopic repair of rotator cuff tears reduces retear rates compared to a control population undergoing arthroscopic repair without BMAC administration. The secondary objectives are to (1) evaluate the survival and incorporation of BMAC labeled cells with MRI imaging using the Ferumoxytol infusion stem cell labeling technique, and (2) determine if administration of BMAC leads to better clinical outcomes as measured by ASES, UCLA and Constant scoring metrics.
