1. An anchor for use in forming a flexible synthetic strand construct within a bone tunnel bored through a first bone portion, the bone tunnel having a first end adjacent to a first surface of the first bone portion and a second end near a second surface of the first bone portion, the anchor comprising:
a head having a proximal side and a distal side, the distal side configured to abut the first surface of first the bone portion about the first end of the bone tunnel;
a longitudinal shank protruding distally from the head from a proximal end of the longitudinal shank to a distal end along a longitudinal axis, wherein the longitudinal shank is configured for insertion into the bone tunnel from the first end of the bone tunnel toward the second end of the bone tunnel, wherein:
an axial hole that extends into the anchor along the longitudinal axis;
the longitudinal shank defining an entirety of a receiver, wherein the axial hole extends through the receiver, and the receiver has internal threads so as to define a threaded portion, the threads configured to rotationally receive external threads of a set screw in the axial hole to lock the flexible synthetic strand relative to the axial hole, wherein the threaded portion defines a converging portion that converges as it extends distally, and the converging portion is threaded;
a length of the shank approximates a length of the bone tunnel; and
when, in passing from or to a separate strand fixation, a flexible synthetic strand enters or exits the axial hole at the distal end of the shank, the shank provides a bone tunnel protection sleeve that prevents transverse movement of the flexible synthetic strand relative to the second end of the bone tunnel, thereby preventing bone abrasion within the bone tunnel.
