PurposeTo report the retear rate and retear pattern after double-row arthroscopic rotator cuff repair (DR-ARCR) with the use of absorbable sutures as medial anchor sutures and to address the advantage of the use of absorbable sutures in medial-row anchors.MethodsFifty-seven shoulders (22 male and 35 female patients; mean age, 66.1 years) with complete rotator cuff tears treated with DR-ARCR using absorbable mattress sutures as medial-row anchor sutures were included in the study. They included 35 medium, 17 large, and 5 massive tears. For the medial row, medial anchor sutures were replaced with absorbable mattress sutures. High-strength simple sutures were used for the lateral anchors. We evaluated retear patterns by magnetic resonance imaging examinations performed at 1 month, 3 months, 6 months, and 1 year postoperatively. The clinical conditions of all patients preoperatively and 2 years postoperatively were assessed by the University of California, Los Angeles rating scale and the American Shoulder and Elbow Surgeons shoulder index.ResultsA complete retear of the tendon at the footprint was observed in 5 shoulders. Complete discontinuity at the middle of the tendon around the medial-row anchors with a footprint remnant was observed in 1 shoulder. A thinned repaired rotator cuff was observed in 2 shoulders because of a partial retear of the deep layer. The overall retear rate was 14%. From before to after surgery, the University of California, Los Angeles score significantly improved from 18.4 to 32.9 (P < .0001) and the American Shoulder and Elbow Surgeons index improved from 55.1 to 87.7 (P < .0001). No complications were observed.ConclusionsThe retear rates after DR-ARCR with absorbable sutures as medial-row anchors were 8.8% for complete retears of the tendon at the footprint and 1.7% for complete discontinuity of tendon around the medial-row anchors. This procedure provided a low retear rate around the medial-row anchors.Level Of EvidenceLevel IV, therapeutic case series.Copyright © 2015 Arthroscopy Association of North America.
