Description
Purpose To evaluate whether the use of knotless lateral anchors in a suture bridge construct produces better contact area and pressure parameters than a suture bridge construct with standard lateral anchors which require knots or a double row. The hypothesis was that knotless lateral anchors would produce better contact area and pressure parameters than the other two constructs. Methods A total of fifteen matched pairs of cadaveric shoulders were divided into three groups. In Group 1, a suture bridge using knotless anchors for the lateral row was performed on five shoulders. A suture bridge using standard lateral row anchors that require knots was performed on the contralateral shoulders. In Group 2, suture bridge with knotless lateral row anchors was compared with double row repair. In Group 3, suture bridge using standard lateral row anchors was compared with double row repair. The contact conditions of the rotator cuff footprint were measured using pressure sensitive film. Results There were no statistically significant differences between any of the techniques regarding Contact Area F(2, 15.7) = 3.09, P = 0.07 or Mean Contact Pressure F(2, 15.1) = 2.35, P = 0.12. A post-hoc power analysis suggests differences between techniques are likely less than 91–113 mm2 for area and 0.071-0.089 N for pressure. Conclusions The use of knotless anchors in the lateral row of a suture bridge repair did not increase the footprint contact area or contact pressure when compared to a suture bridge repair requiring knots laterally or to a double row repair
