    Rotator Cuff Repair Augmented With Interpositional Nanofiber Scaffold
    (Elsevier, 2022-12-21) Beleckas, Casey M.; Bishai, Shariff K.; Badman, Brian L.; Orthopaedic Surgery, School of Medicine
    Despite advances in arthroscopic rotator cuff repair, failure rates up to 94% have been reported in the literature for large tears, with rates as high as 36% for small and medium tears. One strategy for improving outcomes is augmentation with a patch, which has typically been incorporated onto the bursal portion of the repaired tendon and been made up of either dermal or bovine collagen tissue. The Rotium wick (Atreon Orthopedics, Columbus, OH)-an interpositional augmentation-is a nanofiber scaffold that is meant to be sandwiched between the rotator cuff and humerus at the bone-tendon interface and is currently the only implant approved by the US Food and Drug Administration to be used in this manner. The scaffold works to improve the cellular organization of the basement membrane during tendon healing at the enthesis and, in a recent sheep study, has been shown to better replicate the natural Sharpey-like fibers similar to the native tendon and increase the strength of the repair more rapidly. The purpose of this Technical Note is to describe the means for use of an interpositional nanofiber scaffold for arthroscopic rotator cuff repair.
