Chronic massive rotator cuff tears (MMRCTs) are a significant orthopedic challenge, often leading to significant shoulder pain and functional impairment. While surgical intervention is a common treatment approach, long-term outcomes and the optimal surgical technique remain debatable. Arthroscopic debridement, subacromial decompression, and biceps tenotomy are frequently employed procedures, but their long-term effectiveness in managing MMRCTs is not fully understood. A comprehensive understanding of the long-term outcomes of these procedures is crucial for guiding clinical decision-making and patient counseling.

The study aims to evaluate the long-term clinical and functional outcomes of arthroscopic debridement, subacromial decompression, and biceps tenotomy in patients with chronic massive rotator cuff tears. By analyzing a cohort of patients who underwent these procedures, we will assess factors influencing long-term outcomes, such as patient demographics, preoperative functional status, and surgical technique. Furthermore, we will compare the long-term results of this surgical approach to other treatment modalities, including open repair and conservative management.

Inclusion Criteria:

• Patient who had arthroscopic debridement with subacromial decompression and biceps tenotomy without rotator cuff repair for chronic massive Rotator Cuff Tears

Exclusion Criteria:

• Patient who hadn't met the requirements for arthroscopic debridement with subacromial decompression and biceps tenotomy without rotator cuff repair for chronic massive Rotator Cuff Tears

From Oct 2018 to Jan 2021, 23 patients who had chronic massive RCTs received arthroscopic management for their RCTs and were followed as short-term follow-up for 3 months after surgery. Then, patients were asked to attend the Orthopedic outpatient clinic every three months for assessment to get the outcomes of the long-term follow-up. The preoperative, operative, immediate postoperative, and short-term follow-up data were collected from patients' files.
