Abstract
Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.
