A suture anchoring system comprising: an implant body (210; 1404; 1504) extending substantially longitudinally from a proximal end to a distal end, the implant body comprising: an insertion nose at the distal end, the insertion nose being configured for insertion into bone; a slot formed in the implant body, the slot extending at least partially longitudinally, the slot having a slot proximal edge and a slot distal edge; and a slider (110; 1402; 1502; 1602) comprising a slider proximal edge and a slider distal edge; characterized in that the slider (110; 1402; 1502; 1602) is configured to slide within the slot both before and after implantation of the implant body (210; 1404; 1504), in that a first aperture and a second aperture for selectively receiving a suture (612, 614; 802, 804) in a knotless configuration or a knotted configuration of the suture anchoring system are at least partially formed in the suture anchoring system, respectively, by the slot distal edge and the slider distal edge for the first aperture and by the slot proximal edge and the slider proximal edge for the second aperture, which is located proximally with respect to the first aperture, in that a suture passed through only one of the first and second apertures (230, 232) before implantation is moveable freely in both directions after implantation, and in that a suture threaded, before implantation, through one of the first and second apertures (230, 232), around the slider (110; 1402; 1502; 1602), and back through the other of the first and second apertures (230, 232) is, after implantation, moveable freely in a first direction but substantially inhibited from moving in a second direction opposite the first direction when, upon movement in the second direction, the suture disposed in the first aperture pushes the slider (110; 1402; 1502; 1602) such that the suture disposed in the second aperture is pinched between the slider proximal edge and the slot proximal edge. an implant body (210; 1404; 1504) extending substantially longitudinally from a proximal end to a distal end, the implant body comprising: an insertion nose at the distal end, the insertion nose being configured for insertion into bone; a slot formed in the implant body, the slot extending at least partially longitudinally, the slot having a slot proximal edge and a slot distal edge; and an insertion nose at the distal end, the insertion nose being configured for insertion into bone; a slot formed in the implant body, the slot extending at least partially longitudinally, the slot having a slot proximal edge and a slot distal edge; and a slider (110; 1402; 1502; 1602) comprising a slider proximal edge and a slider distal edge; characterized in that the slider (110; 1402; 1502; 1602) is configured to slide within the slot both before and after implantation of the implant body (210; 1404; 1504), in that a first aperture and a second aperture for selectively receiving a suture (612, 614; 802, 804) in a knotless configuration or a knotted configuration of the suture anchoring system are at least partially formed in the suture anchoring system, respectively, by the slot distal edge and the slider distal edge for the first aperture and by the slot proximal edge and the slider proximal edge for the second aperture, which is located proximally with respect to the first aperture, in that a suture passed through only one of the first and second apertures (230, 232) before implantation is moveable freely in both directions after implantation, and in that a suture threaded, before implantation, through one of the first and second apertures (230, 232), around the slider (110; 1402; 1502; 1602), and back through the other of the first and second apertures (230, 232) is, after implantation, moveable freely in a first direction but substantially inhibited from moving in a second direction opposite the first direction when, upon movement in the second direction, the suture disposed in the first aperture pushes the slider (110; 1402; 1502; 1602) such that the suture disposed in the second aperture is pinched between the slider proximal edge and the slot proximal edge.
