Abstract

Apparatuses and methods are provided for arthroscopic rotator cuff repair incorporating a transhumeral bone tunnel. The apparatus comprises a number of components that can also be considered a repair system to include a drill guide, a marking hook, and a drill with a removable tip that serves as a bone anchor. In another aspect, the invention provides a suture especially adapted for securing both soft tissue and bone anchors that reduces forces transmitted to the anchors by secondary anchoring of the suture within the bone tunnel based on the geometry of the anchor. In additional aspects of the invention, the components of the drill guide assembly comprise a cannulated marking hook and a drill guide with multiple bores. In additional aspects of the invention, an implantable bone anchor is provided that is especially adapted for placement through a bone tunnel, and wherein the implantable anchor is collapsible to increase the effective size of the anchor for securing the anchor to the far side opening of the bone tunnel through which the anchor was placed. Methods of the invention include a method of arthroscopic repair of a rotator cuff, and methods of activating an implantable anchor.
