Core Tip

Core tip: We report our first results derived from a porcine model investigating different suture configurations in the double-row technique, and how this influences the contact area of the rotator cuff tendon to bone. This study demonstrates for the first time that there is no statistical difference in tendon to bone contact area when using a 3 or 4-suture anchor construct, suggesting that the 3-anchor construct may be a comparable alternative to the standard 4-anchor construct in terms of efficacy.
