Interventions

Procedure/Surgery : This randomized, single-center clinical trial enrolls patients with massive rotator cuff tears to compare the clinical effectiveness of two surgical interventions: extreme medializ

however, excessive medialization may reduce the abduction moment arm and potentially impair function. In Group 2, muscle advancement (MA) repair was initially described as an open procedure by Debeyr

nonetheless, high-quality randomized comparative trials and long-term follow-up data remain limited.

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Persistent symptoms despite =3 months of conservative treatment. MRI evidence of either (a) a posterosuperior rotator cuff tear =3 cm; or (b) a posterosuperior rotator cuff tear =2.5 cm with a repairable subscapularis tear, for which surgery is indicated, and in whom a tension-free anatomic repair cannot be achieved with standard rotator cuff repair alone. Intact deltoid function (no deltoid dysfunction).

Exclusion criteria

Exclusion criteria: Prior surgery on the ipsilateral shoulder. History of ipsilateral shoulder arthritis or prior treatment for infection in the ipsilateral shoulder. Full-thickness articular cartilage loss on MRI (glenohumeral joint). Acute, trauma-related rotator cuff tear. Inability to comply with =1 year of outpatient follow-up. Pregnant or likely to become pregnant during the study period. Pain =3 on the visual analogue scale (VAS) in the contralateral (non-operative) shoulder. Autoimmune disease or HIV antibody–positive status. Declines to provide informed consent. Unable to communicate in Korean such that informed consent cannot be obtained. Currently participating in another clinical trial. Psychiatric illness, risk of dementia, or any other condition deemed by the investigators to make the patient unsuitable for participation.
