Midterm outcomes of arthroscopic rotator cuff repair in patients aged 75 years and older.

BACKGROUND: Full-thickness rotator cuff tears remain a significant cause of pain and dysfunction in the elderly. Substantial improvement in pain and functional outcomes with arthroscopic cuff repair is possible. Recent data has shown that patients older than 70-75 years still have clinical improvement with operative rotator cuff repair. MATERIALS AND METHODS: This is a retrospective study of patients aged ≥75 years undergoing arthroscopic rotator cuff repair at a minimum of 24 months after surgery. Outcome measurements included range of motion (ROM), visual analog scale (VAS) pain scores, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores, Single Assessment Numeric Evaluation (SANE) scores, and Short Form Health Survey (SF-12) scores. Reoperation and rates of conversion to reverse shoulder arthroplasty (RSA) were determined. RESULTS: Eighty-three patients were included with an average follow-up of 56.9 ± 25.9 months (range 24-127 months). Six (7.2%) patients had additional surgery, including 3 revision rotator cuff repairs for retear, 2 conversion to RSA, and 1 capsular release and loose anchor removal. There were statistically significant improvements in shoulder ROM, ASES, SANE, VAS, and SF-12 scores postoperatively. CONCLUSION: Rotator cuff repair in select patients aged ≥75 years results in reliable improvements in pain and function. There was a low reoperation rate or conversion to RSA (7.2%) at midterm follow-up. This study indicates a role for rotator cuff repair in an elderly population and argues against the routine use of reverse arthroplasty for repairable rotator cuff tears in this population.
