Abstract: Some embodiments of the present invention include a suture anchor with both knotless and knotted suture attachment capabilities, as well as methods for loading the suture in knotless and knotted configurations. Some embodiments of the present invention include a suture anchor with an inner implant body with a spreader that slides in relation to an outer expandable collar, such that pushing the expandable collar distally with an inserter causes the spreader to expand the collar against the surrounding bone to secure the suture anchor in place. Such embodiments may also include a detachment or breakaway feature between the inserter and the suture anchor to permit separation after anchor deployment. Some embodiments of the present invention include methods for deploying such suture anchors and expanding the expandable collars and/or detaching the inserter tools. Embodiments of the present invention may be used in various orthopedic applications such as, for example, shoulder repair.
