1. A device comprising:
an anchor including:
a helicoil portion having a plurality of coils defining openings in between the plurality of coils, the openings in communication with an interior volume of the anchor, and a drive surface extending longitudinally along at least a portion of the helicoil portion and extending among and contacting at least two adjacent coils of the plurality of coils and helically along an inner surface of each of the at least two adjacent coils, a collective area of the drive surface on a single full turn coil of one of the at least two adjacent coils occupying less than 50% of the inner surface of the single full turn coil; and
the helicoil portion extending longitudinally from a proximal portion to a distal portion; and
an inserter, comprising a handle, adapted to couple with the anchor for insertion of the anchor into bone;
wherein a majority of an area defined between the at least two adjacent coils at the proximal portion comprises the openings; and
wherein the drive surface at the proximal portion does not comprise a projection extending into the interior volume of the anchor.
