Minimum 5-Year Clinical Outcomes of Arthroscopically Repaired Massive Rotator Cuff Tears: Effect of Age on Clinical Outcomes.

Background: Massive rotator cuff tears (MRCTs) can be challenging to treat, and the efficacy of repair of MRCTs in older patients has been debated.
Purpose: To report minimum 5-year outcomes after primary arthroscopic rotator cuff repair of MRCT and determine whether age affects outcomes.
Study Design: Case series; Level of evidence 4.
Methods: The study included consecutive patients with MRCTs who were treated with arthroscopic rotator cuff repair by a single surgeon between February 2006 and October 2016. MRCTs were defined as ≥2 affected tendons with tendon retraction to the glenoid rim and/or a minimum exposed greater tuberosity of ≥67. Patient-reported outcome (PRO) data collected preoperatively and at a minimum of 5 years included the American Shoulder and Elbow Surgeons (ASES) score; Single Assessment Numeric Evaluation (SANE) score; the shortened version of the Disabilities of the Arm, Shoulder and Hand score (QuickDASH); the 12-Item Short Form Health Survey (SF-12) Physical Component Summary (PCS); and patient satisfaction. Surgical failure was defined as subsequent revision rotator cuff surgery or conversion to reverse total shoulder arthroplasty. Regression analysis was performed to determine whether age had an effect on clinical outcomes.
Results: A total of 53 shoulders in 51 patients (mean age, 59.7 years; range, 39.6-73.8 years; 34 male, 19 female) met inclusion criteria with a mean follow-up of 8.1 years (range, 5.0-12.1 years). Three shoulders (5.7%) failed at 2.4, 6.0, and 7.1 years. Minimum 5-year follow-up was obtained in 45 of the remaining 50 shoulders (90%). Mean PROs improved as follows: ASES from 58.8 to 96.9 ( P < .001), SANE from 60.5 to 88.5 ( P < .001), QuickDASH from 34.2 to 6.8 ( P < .001), and SF-12 PCS from 41.1 to 52.2 ( P < .001). Patient satisfaction was a median of 10 (on a scale of 1-10). Age was not associated with any PRO measures postoperatively ( P > .05).
Conclusion: This study demonstrated significantly improved clinical scores, decreased pain, and increased return to activity for patients with MRCT at midterm follow-up (mean, 8.1 years; range, 5.0-12.1 years). In this patient cohort, no association was found between age and clinical outcomes.
