Abstract

The repair of torn tendon/ligament by anchoring the tendon to a anchor affixed to the bone is by a suture judiciously looped in the tissue to form a double strand holding the tending to cinch to the bone trough and securing the strand to and downstream of the anchor. This enhances the pull-out resistance of the suture from the tendon. The suture, secured by a knot or clamp, is at the end of the tendon and not under it so as to allow the surgeon to maintain constant apposition to the bone while the knot is being tied. The knot is in the bone trough and not over the tendon avoiding abrasion of the suture by other parts of the body. When the operation is done by arthroscopic surgery the ability for cinching the tissue down to the bone and assessing how tightly the tissue is apposed to the bone and tying the knot while maintaining secure apposition of the tendon to the bone is improved.

Claims

1. The method of tying torn tissue with suture to a bone that has been prepared by burring a trough in the bone and fixing an anchor in or in close probity to the trough and tying the suture to the anchor comprising the steps of:

i) sewing the tendon with suture so that the suture forms a double loop over the tendon and is drawn through a loop defined by the suture;

ii) drawing the suture through eyelet of the anchor so that the juncture of the suture and the double loop is adjacent the bone and the ends of the suture is downstream of the anchor; and

iii) tying the ends of the suture together with a surgical knot.

2. The method as claimed in claim 1 including a clamp replacing the knot claimed in the step iii.

3. The method of tying torn tissue with suture to a bone that has been prepared by burring a trough in the bone and fixing an anchor in or in close proximity to the trough and tying the suture to the anchor comprising the steps of:

i) cutting through the skin and tissue of the patient to expose the area of the patient including the adjacent bone that requires repair of a tendon or ligament;

ii) burring a surface of the bone exposed in step i to form a trough and a roughened surface of the bone;

iii) inserting an anchor into the trough formed in step ii.

iv) sewing the tendon or ligament with a suture so that two portions of the suture pass through the tendon or ligament and form a loop and drawing the two portions of the suture through the loop;

v) drawing the two portions of the suture extending downstream of the loop into an eyelet of the anchor; and

vi) tying the two portions of the suture downstream of the eyelet to form a knot to secure the tendon or ligament to cinch to the bone of the patient.

4. The method of tying torn tissue with suture to a bone that has been prepared by burring a trough in the bone and fixing an anchor in or in close proximity to the trough and tying the suture to the anchor comprising the steps of:

i) cutting through the skin and tissue of the patient to expose the area of the patient including the adjacent bone that requires repair of a tendon or ligament;

ii) burring a surface of the bone exposed in step i to form a trough and a roughened surface of the bone;

iii) inserting an anchor into the trough formed in step ii.

iv) sewing the tendon or ligament with a suture so that two portions of the suture pass through the tendon or ligament and form a loop and drawing the two portions of the suture through the loop;

v) drawing the two portions of the suture extending downstream of the loop into an eyelet of the anchor; and

vi) tying the two portions of the suture downstream of the eyelet to form a knot to secure the tendon or ligament to cinch to the bone of the patient.
