PurposeThe first aim of this study was to introduce the concept of hybrid repair (incomplete repair) for large to massive rotator cuff tears and to report clinical results and structural integrity of patients with a minimum 2-year follow-up. The second aim was to compare arthroscopic hybrid repair with partial repair for large to massive rotator cuff tears.MethodsWe retrospectively evaluated 65 patients who underwent arthroscopic incomplete (hybrid) repair (45 patients) or partial repair (20 patients) for large to massive cuff tears from March 2011 to January 2015. The pain visual analog scale, function visual analog scale, American Shoulder and Elbow Surgeons, and Constant scores and range of motion (ROM) (active flexion, elevation, abduction, external rotation, and internal rotation) were assessed preoperatively, at first follow-up (approximately 6 months postoperatively), at second follow-up (1 year postoperatively), and at final follow-up (2 years postoperatively). The healing status of the repaired tendon was evaluated with postoperative magnetic resonance imaging, with a focus on tendon integrity.ResultsComparisons of the preoperative values and final follow-up results of hybrid repair showed significant improvement in the mean pain visual analog scale score (5.56 and 0.93, respectively), mean function visual analog scale score (4.77 and 8.59, respectively), and questionnaire results (American Shoulder and Elbow Surgeons score, 44.89 and 84.67, respectively; Constant score, 44.27 and 73.46, respectively) (all P ≤ .001). Most shoulder ROM measures showed some improvement compared with presurgical ROM at last follow-up (≥2 years). However, there was no statistical significance. Retears occurred in 9 patients (20%) in the hybrid-repair group. Most of the postoperative clinical outcomes showed excellent results with hybrid repair compared with partial repair.ConclusionsArthroscopic incomplete repair (hybrid technique) showed more satisfactory clinical trial outcomes than partial repair of large to massive rotator cuff tears. Therefore, we propose the use of incomplete repair, which provides improvements in both pain and functional outcomes, as another repair option for large to massive rotator cuff tears.Level Of EvidenceLevel III, retrospective comparative study.Copyright © 2018 Arthroscopy Association of North America.
