Long-Term Follow-up Study to Evaluate Long-Term Safety and Efficacy of Allogenic Umbilical Cord-derived Mesenchymal Stem Cell in Patients With Rotator Cuff Disease

The Shoulder Pain and Disability Index (SPADI) is a self-administered questionnaire that consists of two dimensions, one for pain and the other for functional activities. The pain dimension consists of five questions regarding the severity of an individual's pain. Functional activities are assessed with eight questions designed to measure the degree of difficulty an individual has with various activities of daily living that require upper-extremity use. The minimum value is 0 and the maximum value is 10. "0" means no pain and "10" means the worst pain imaginable in the pain section. "0" means no difficulty and "10" means so difficult it requires help in the pain section.

The Constant score assesses pain, function, ROM, and strength. Pain is allotted a maximum of 15 points, activities of daily living (function)20 points, ROM 40 points, and strength 25 points. The component scores are summated to achieve a maximum possible total score of 100.

Using a ruler, the score is determined by measuring the distance (mm) on the 100mm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity.

Adverse events will be collected from Visit 2 to Visit 6. The following information will be collected: adverse event term, start date/end date, adverse event category, severity of the adverse event, causal relationship with the investigational product, seriousness of the adverse event, and final outcome.
