Changes in the size of rotator cuff tears determined by MRI
Lasso di tempo: 6months
|
The location, width (AP size), length (ML size), and depth of the rotator cuff tear will be measured on oblique coronal, axial, and sagittal MRI images where the tear is most clearly visualized.
The same measurements will be performed on the corresponding planes after administration of the investigational product and compared with those obtained before administration.

Shoulder pain and disability index(SPADI) Score
Lasso di tempo: 6months
|
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.

6months
|
|
Constant-Murley score
Lasso di tempo: 6months
|
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.

|
|
Visual Analog Scale(VAS) pain
Lasso di tempo: 6months
|
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.

Histological Evaluation of Tendon Tissue
Lasso di tempo: 6months
|
If tendon regeneration at the lesion site is confirmed by arthroscopic examination before and after administration of the investigational product, a tissue sample approximately 2 mm in diameter will be collected from the regenerated area and evaluated using the modified Astrom and Movin scoring system.
|
6months
|
|
Short tandem repeat (STR) evaluation of tendon tissue
Lasso di tempo: 6months
|
STR testing will be performed using a portion of the collected tendon tissue.
The results will be compared with those of the investigational product and the clinical study participant's blood to evaluate the origin of the regenerated tendon tissue.
