[Arthroscopic treatment of eldly with massive rotator cuff tear]

Objective: To investigate the surgical technique and clinical efficacy of arthroscopic treatment of the elderly patients with massive rotator cuff tear. Methods: From June 2012 to June 2015, thirty-six patients with massive rotator cuff tear were treated with arthroscopic and followed up. The visual analog scale(VAS)pain score, University of California Los Angeles (UCLA) scores, Constant scores and American Shoulder and Elbow Surgeons scale(ASES)were used before and after the arthroscopic surgery. Results: All the patients were followed up for average of 18.5 (12 to 30) months.Before arthroscopic surgery, the VAS, UCLA, Constant, ASES were (6.1±2.2), (10.6±4.3), (40.3±10.5) and (28.8±18.5) points; the average flexion of the shoulder was (76.5±42.6)°, the average abduction of the shoulder was (72.4±35.2)°, the average external rotation of the shoulder was(26.6±22.2)° and the average internal rotation of the shoulder was (20.2±6.2)° respectively.These scores were improved to (1.4±1.2), (30.4±5.2), (82.6±12.6), and (78.8±22.6) points, the average flexion of the shoulder was improved to (152.8±25.6)°, the average abduction of the shoulder was improved to (120.6±32.8)°, the average external rotation of the shoulder was improved to (42.6±16.2)° and the average internal rotation of the shoulder was improved to (38.4±5.6)° after one-year follow-up period.Improvement in these scores and range of motion(ROM) were significant difference(P<0.05). Conclusion: Arthroscopic repair can effectively treat the eldly patient with massive rotator cuff tear and obviously improve the function of shoulder joint. The surgery has a clinical application value.
