Prevention, Reduction, and Stabilization of Dog-Ear Deformities During Arthroscopic Rotator Cuff Repair

Arthroscopic rotator cuff repairs (ARCRs) are common procedures that have been increasing in incidence. When performing ARCR, the surgeon often identifies an undesirable flap or fold, referred to as a “dog-ear” deformity, between sutures or knots. The height and/or thickness of a dog-ear deformity may decrease the rotator cuff–to–acromion distance, resulting in possible impingement and repair compromise. Furthermore, the goal of ARCR is to achieve complete restoration of the tendon-to-footprint relation. To restore the entire footprint, this lesion must be reduced and stabilized. We present a technique using looped sutures to augment the rotator cuff repair and prevent dog-ear formation.
