Editorial Commentary: Improving Strength and Clinical Outcomes After Rotator Cuff Repair-Role of Choosing Single- Versus Double-Row Repair.

The controversy as to what is the best technique to repair a rotator cuff continues, with single-anchor row versus double-row techniques being highlighted. The literature has presented multiple studies with clinical outcomes being similar, even though double-row linked and transosseous-equivalent repairs have a higher success rate with postoperative imaging. Clinical outcome instruments weigh pain as a major criterion, but strength improvement favors an intact repair. Treatment of chronic rotator cuff tears often yields muscular changes that may compromise the strength-improvement portion of the outcome. Larger tears benefit from additional fixation, and tissue loss continues to require adjustments to the repair strategy. Attempting a repair that emphasizes footprint coverage may over-tension the cuff repair and risk shoulder stiffness and medial failure of the repair. By use of a 3-dimensional spherical attachment surface, a linked infraspinatus repair can be combined with an anteromedial supraspinatus repair to create a lower-tensioned secure repair. Additional grafting methods, including use of the biceps, may provide additional strength to the repair construct.
