What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Shoulder pain and disability index(SPADI) Score
Time Frame: 6 months
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.
6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Constant-Murley score
Time Frame: 6 months
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.
6 months
Visual Analog Scale(VAS) pain in motion
Time Frame: 6 months
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.

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in degeneration score compared to baseline and the rate of change through histological examination
Time Frame: 6 months

When tendon regeneration is identified in the lesion area through arthroscopic examination, a tissue sample approximately 2 mm in diameter is collected from the regenerated site and evaluated using the modified Astrom & Movin scoring system.

The evaluation method consists of seven assessment variables(Fiber structure, Fiber arrangement, Rounding of the nuclei, Variations in cellularity, Increased vascularity, Decreased stainability, Hyalinization), each scored on a scale from 0 to 3, with 0 indicating normal and 3 representing the most severe abnormality. The scores are summed to calculate the tendon degeneration score, which ranges from 0 to 21. A score closer to 0 indicates normal tendon condition, while a score closer to 21 reflects severe degenerative changes.
