1. A surgical method of affixing tissue to a bone, the method comprising:
coupling a suture to tissue such that two suture limbs extend from the tissue;
passing each of the two suture limbs into and through a first opening formed by a cutout in a sidewall of a distal tip portion of a suture anchor, at least a portion of a longitudinal lumen of the suture anchor being in communication with the first opening to receive each of the two suture limbs therethrough, the longitudinal lumen having one or more suture engagement features such that the two suture limbs are slidably disposed with respect to the one or more suture engagement features;
extending at least one limb of the two suture limbs through the portion of the longitudinal lumen and out of the longitudinal lumen through a second opening formed in a sidewall of a proximal portion of the suture anchor, the second opening being located proximal to the first opening and on a side of a central longitudinal axis that extends centrally through the longitudinal lumen of the suture anchor that is opposed to a side from the profile view in which the first opening is formed such that the at least one limb extends into and out of the longitudinal lumen on opposite sides of the central longitudinal axis, the at least one limb extending proximally through the longitudinal lumen as it extends between the first and second openings;
inserting the suture anchor into a bore formed in bone; and
applying tension to at least one of the two suture limbs to draw the tissue towards the bone; and
advancing the suture anchor distally into the bore to lock a location of the two suture limbs, and thus the tissue coupled to the bone, at a location relative to the bone.
