A method of using a knotless suture anchor includes boring a nest in a bone, driving the suture anchor into the nest, tensioning an unknotted suture; and securing the unknotted suture in an anchor body by contacting the unknotted suture with an inner bottom surface of the well and a bottom face of an anchor plug, where the suture anchor includes the anchor body including a well, a top surface, a bottom surface distal to the top surface, a transverse bore proximal to the inner bottom surface of the well, and he unknotted suture threaded through the transverse bore; where the well includes an outer surface; an inner surface; and the inner bottom surface; and where the anchor plug includes a post; and the bottom face.
