Various devices, systems, and methods for anchoring sutures are provided In general, a suture anchor can include a groove formed in an exterior surface thereof and configured to seat a suture at least partially therein. The suture can be configured to automatically become seated in the groove during the advancement of the anchor into bone, such as by being rotated therein using a driver tool. The suture and the groove can have cooperating sizes such that the suture seated in the groove extends radially outward therefrom to be partially located outside of the anchor. This external portion of the suture can be press fit between the anchor and the bone, thereby securing both the anchor and the suture to the bone. This securing can occur as part of driving the anchor into bone.
