Abstract:
1. An adjustable anchor system for securing tissue to bone, comprising; an anchor having at least one passage extending from a proximal end toward a distal end, the passage including a restriction formed distally of the proximal end of the anchor, and the anchor having at least one bone-engaging feature disposed between the proximal and distal ends; a first material formed as a closed loop and capable of being placed through a portion of the tissue; a second filament having a terminal end, a post limb and a sliding knot tied between the terminal end and the post limb to establish an elongated, adjustable-length loop which extends beyond the proximal end of the anchor and captures the closed loop of the first material; and the knot of the second filament being located such that a portion of the anchor is disposed between the knot and the first material, with the knot located at a distal portion of the anchor and the first material located proximal of the proximal end of the anchor, the knot being restrainable by the restriction when tension is applied to the post limb to shorten the elongated loop to draw the tissue toward the anchor.
