Abstract
A transosseous-equivalent rotator cuff repair has shown improved biomechanical characteristics compared to other more cumbersome arthroscopic double row repairs. However, the transosseous equivalent repair, which requires knot tying, still can be challenging when tensioning the repair construct. We hypothesized that a knotless dual row loop repair has similar biomechanical characteristics to the transosseous-equivalent rotator cuff repair. Therefore, the objective of this study was to quantify and compare the biomechanical characteristics of a knotless double row repair and transosseous equivalent rotator cuff repair using matched pair shoulders. ©2009 ASME.
