Most surgeons who repair rotator cuff tears arthroscopically do so using either a single-row (SR) or double-row technique. While there is still controversy regarding which technique is superior, most surgeons use both techniques, taking into consideration characteristics of the rotator cuff tear to help them decide which technique to use in a particular patient. This paper describes 2 methods of performing an isolated SR supraspinatus repair. In addition, it provides the authors’ indications for a SR repair and discusses the clinical outcomes available to date comparing SR and double-row rotator cuff repairs. Regardless of which technique is used, meticulous attention should be paid to the arthroscopic anatomy, characteristics of the rotator cuff tear, and patient’s functional demands to maximize the chance of a successful result.
