Mesenchymal Stem Cell Augmentation in Patients Undergoing Arthroscopic Rotator Cuff Repair

Patients undergoing mesenchymal stem cell augmentation will receive a total injection of 6 milliliters (mL). Of this, 3 mL will be injected in the tendon at the junction between bone and tendon, while 3 mL will be injected in the bone at the site of the surgical footprint.

All patients will undergo full thickness rotator cuff repair using a double row, transosseous-equivalent (TOE) repair with anchor/suture technique. Acromioplasty will be performed in all patients. Alternate procedures such as biceps tenotomy/tenodesis and distal clavicle excision will be performed at the discretion of the surgeon and recorded.
