Details and patient eligibility


Main purpose of this study is to evaluate efficacy of allogenic adipose-derived mesenchymal stem cells in treatment of tendon injury. ALLO-ASC will be administrated to the patients with supraspinatus partial thickness tear by ultrasonographic guided injection.

Full description

Injection volume depends on the size of lesion on ultrasound examination. And all injection will be done under ultrasound guidance. Double blind Randomized placebo controlled study will be done with following 3 groups. Each group will have 8 people, so, the total patients will be 24 people.

Stem cell treatment group : stem cell 0.5cc (Total: 10 million cells) + Fibrin glue 0.5cc + range of motion exercise Active control (fibrin glue) group : Normal saline 0.5cc + Fibrin glue 0.5cc + range of motion exercise Control (normal saline) group : Normal saline 0.5cc + Normal saline 0.5cc + range of motion exercise

The investigators will compare the efficacy difference with VAS(visual analog scale, primary outcome), ASES(American Shoulder and Elbow Surgeons) Score, UCLA(University of California, Los Angles) Shoulder Score, DASH(The Disabilities of the Arm, Shoulder and Hand) Score and change of tear size compared to the baseline image assessed by MRI. These measurement will be done at 6 and 12 weeks after injections and long-term follow-up will be also planned to 6 months, 12months and 24 months except for the evaluation of the tear size which will be done at baseline, 3 months and 24 months after the intervention.
