Trial Outcomes & Findings for Mesenchymal Stem Cell Augmentation in Patients Undergoing Arthroscopic Rotator Cuff Repair (NCT NCT02484950)
NCT ID: NCT02484950
Last Updated: 2025-07-28
Results Overview
The American Shoulder and Elbow Surgeons (ASES) score is a patient-reported score that measures shoulder pain, activity level and stability. The score ranges from 0 to 100, with higher scores indicating better shoulder function. Excellent: 90-100 points Good: 70-89 points Fair: 40-49 points Poor: Less than 39 points

Rotator Cuff Repair With Stem Cells
Using clinically accepted methods, subjects will undergo bone marrow aspiration (from hip, proximal humerus or tibia) through a small incision prior to arthroscopy in the group undergoing MSC augmentation. They will then undergo arthroscopic full thickness rotator cuff repair using a double row, TOE anchor/suture technique with mesenchymal stem cell augmentation.
Mesenchymal stem cell augmentation in 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.
Standard arthroscopic rotator cuff repair: 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.

Rotator Cuff Repair Without Stem Cells
Subjects will undergo arthroscopic full thickness rotator cuff repair using a double row, TOE anchor/suture technique, without augmentation of mesenchymal stem cells. To maintain patient blinding, all patients will receive a small incision around the site of expected bone marrow aspiration (hip, proximal humerus, or tibia), regardless of whether or not they receive bone marrow.

All patients underwent a shoulder exam pre-operatively as well as at 3 months, 6 months, 1 year and 2 years post-operatively. All patients completed the Standardized Shoulder Test (SST), ASES, Constant, SANE, and VR/SF-12 questionnaires preoperatively as well as 3 months, 6 months, 12 months, 18 months and 24 months postoperatively.

PRIMARY outcome
Timeframe: One yearPopulation: This study analyzed the efficacy of using autologous Bone Marrow Aspirate Concentrate (BMAC) compared with a control group in the recovery from rotator cuff surgery of the shoulder. The primary analysis focused on the American Shoulder and Elbow Surgeons (ASES) Score at 12 months post-surgery.
The American Shoulder and Elbow Surgeons (ASES) score is a patient-reported score that measures shoulder pain, activity level and stability. The score ranges from 0 to 100, with higher scores indicating better shoulder function. Excellent: 90-100 points Good: 70-89 points Fair: 40-49 points Poor: Less than 39 points
