Inclusion criteria
Inclusion criteria: 1. Age range: 50 years and above. 2. Imaging examination (e.g., MRI) confirms the presence of a large, irreparable rotator cuff tear, and the patient meets the indications for surgical treatment. 3. The patient meets the indications for subacromial balloon implantation, meaning the shoulder joint requires functional restoration through non-traditional repair methods, as traditional surgical methods have failed to repair the rotator cuff tear. 4. The shoulder joint has a certain degree of anterior-posterior balance, making it suitable for balloon implantation. 5. Preoperative shoulder joint functional scores are low, with significant limitation in shoulder range of motion, meeting the functional improvement goals of the study. 6. The patient or their guardian has signed an informed consent form and is willing to participate in the clinical study.
Exclusion criteria
Exclusion criteria: 1. Patients with severe shoulder osteoarthritis, deformity, or other conditions that compromise the restoration of normal shoulder biomechanics. 2. Presence of other serious intra-articular shoulder pathologies, such as tumors or severe infections, which may affect surgical safety and recovery. 3. Patients with severe systemic diseases, such as advanced cardiac disease, hepatic or renal insufficiency, that contraindicate surgery or anesthesia. 4. History of severe allergies, bleeding disorders, or other medical conditions that conflict with surgical intervention. 5. Patients who, due to living conditions or health status, are unable to comply with at least 12 months of follow-up and assessment.
