Rotator cuff–related degenerative shoulder disorders, including rotator cuff tendinopathy, degenerative rotator cuff tears, partial-thickness and full-thickness rotator cuff tears, delamination-like changes, and related symptoms such as shoulder pain, limited range of motion, weakness, night pain, and difficulty with arm elevation.

Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients Who Visited The Affiliated Hospital Of Xuzhou Medical University Between January 2018 And December 2025 For Shoulder Pain, Rotator Cuff Injury, Or Degenerative Shoulder Disorders, Regardless Of Sex. 2. Patients With Complete Shoulder MRI Data. When Necessary, X-Ray, CT, Ultrasound, Or Arthroscopic Data May Be Used As Supplementary Information. The Image Quality Should Be Sufficient For The Evaluation Of Rotator Cuff Injuries And Shoulder-Related Imaging Parameters. 3. Patients Confirmed By Clinical Physical Examination, Imaging Examination, Or Arthroscopy To Have Rotator Cuff–Related Lesions, Including Rotator Cuff Degeneration, Partial-Thickness Or Full-Thickness Rotator Cuff Tears, Subacromial Impingement Syndrome, Acromioclavicular Joint Degeneration, Cystic Changes Of The Greater Tuberosity, Fatty Infiltration And Atrophy Of The Rotator Cuff Muscles, And Other Related Conditions. 4. Patients Whose Shoulder Imaging Findings Can Be Stratified According To The Imaging Parameters Defined In This Study. The Stratification Parameters Include, But Are Not Limited To, Rotator Cuff Tear Type, Tear Size, Tear Thickness, Degree Of Tendon Retraction, Degree Of Fatty Infiltration Of The Rotator Cuff Muscles, Degree Of Muscle Atrophy, Acromial Morphology, Subacromial Space, Severity Of Acromioclavicular Joint Degeneration, And Changes Involving The Humeral Head And Greater Tuberosity. 5. Patients With Relatively Complete Clinical Data, Imaging Data, Surgical Data, And/Or Follow-Up Data Sufficient To Meet The Analytical Requirements Of The Primary Observational Outcomes Of This Study.
Exclusion criteria
Exclusion criteria: 1. Patients With Incomplete Imaging Data Or Poor Image Quality That Prevents Evaluation Of The Primary Observational Parameters. 2. Patients With Severely Incomplete Clinical Data That May Affect The Interpretation Of Study Outcomes. 3. Patients With A History Of Surgery, Severe Trauma, Infection, Or Tumor Involving The Affected Shoulder. 4. Patients With Severe Glenohumeral Osteoarthritis, Severe Shoulder Stiffness, Irreparable Rotator Cuff Tears, Severe Calcific Tendinitis, Or Severe Fatty Infiltration. 5. Patients With Concomitant Periarticular Shoulder Fractures, Dislocation, Osteonecrosis Of The Humeral Head, Inflammatory Arthropathy, Or Neurogenic Shoulder Dysfunction. 6. Patients With Severe Osteoporosis, Severe Joint Degeneration, Significant Dysfunction Of Major Organs, Severe Autoimmune Diseases, Neurological Disorders, Or Psychiatric Disorders That May Affect Examination, Treatment, Or Follow-Up. 7. Patients Who Are Likely To Be Lost To Follow-Up, Have Communication Difficulties, Poor Compliance, Or Are Considered Unsuitable For Inclusion By The Investigators. 8. Imaging data are insufficient, making it impossible to assess the degree of rotator cuff injury, acromion morphology, acromioclavicular joint degeneration, fat infiltration, muscle atrophy, or other morphological stratifications.
