The purpose of the proposed study is to evaluate a new anchor for rotator cuff repair, the Smith & Nephew Healicoil anchor. This anchor utilizes a small open-construct design to promote bone-in growth and potentially allow for the release of bone marrow factors into the repair site. In vivo ovine studies comparing the Arthrex BioComposite Corkscrew FT rotator cuff anchor to the Arthrex SwivelLock anchor have shown superior bone in-growth.
