Sliding and locking surgical knot

A sliding and locking surgical knot, comprising:

• a filament having at a proximal-most end a post including thereon a major loop, minor loop, and at least one coil encircling and bisecting the major loop;
• and
• a distal-most free end of the filament extending from the minor loop;
• wherein pulling the free end effects tightening of the at least one coil about the major loop, minor loop, and post to create a knot which can be locked without the necessity for a half hitch.

A suture retaining structure, comprising:

• a body extending between a first leading end and a second trailing end, the body having thereon at least one bone engaging element;
• a suture receiving aperture within the body;
• and
• a sliding and locking surgical knot extending from the suture receiving aperture, the sliding and locking knot comprising:
• a filament having at a proximal-most end a post including thereon a major loop, minor loop, and at least one coil encircling and bisecting the major loop;
• and
• a distal-most free end of the filament extending from the minor loop;
• wherein pulling the free end effects tightening of the at least one coil about the major loop, minor loop, and post to create a knot which can be locked without the necessity for a half hitch.

A method for anchoring tissue to a bony structure, comprising:

• providing a suture retaining structure, comprising a body extending between a first leading end and second trailing end, the body having thereon at least one bone engaging element, a suture receiving aperture within the elongate body, and a sliding and locking surgical knot extending from the suture receiving aperture, the sliding and locking knot comprising a filament having at a proximal-most end a post including thereon a major loop, minor loop, and at least one coil encircling and bisecting the major loop, and a distal-most free end of the filament extending from the minor loop, wherein pulling the free end effects tightening of the at least one coil about the major loop, minor loop, and post to create a knot which can be locked without the necessity for a half hitch;
• placing a free end of the tissue through the major loop of the sliding and locking knot;
• inserting the suture retaining structure into a bone cavity within the bony structure;
• sliding the knot down the post to bring the tissue proximate to the bony structure;
• and
• locking the knot in place.

A method for anchoring tissue to a bony structure, comprising:

• providing a suture retaining structure, comprising a body extending between a first leading end and second trailing end, the body having thereon at least one bone engaging element, and a suture receiving aperture within the elongate body;
• threading a suture filament through the suture receiving aperture;
• Inserting the suture retaining structure into a bone cavity within the bony structure;
• creating a sliding and locking knot by forming a post at a proximal-most end of the filament and a major loop on the post, threading a distal-most free end of the filament through the major loop to form a minor loop, coiling the free end of the filament around the major loop after the minor loop has been formed to form at least one coil bisecting the major loop, and threading the free end of the filament through the minor loop;
• placing a free end of a soft tissue through the major loop of the sliding and locking knot;
• sliding the knot down the post to bring the tissue proximate to the bony structure;
• and
• locking the knot in place.
