Abstract
A suture anchor system and procedure for securing a suture, into to extend from a bone cortex surface. The system includes forming a hole into a bone cortex surface that is of a diameter and depth to provide a wall surface area that is at least as great as the surface area of an end section of a suture or sutures fitted therein, and, by filling the hole with an adhesive that is allowed to cure, a suture mounting is provided that will have a pullout strength or purchase that is greater than a load as is anticipated to be applied thereto when the suture is used to connect a ligament, or the like, to the bone. To increase which purchase a portion of the hole formed into the bone cortex may be counter bored to form an outwardly extending shirt area to increase the hole wall surface area, the suture may be folded upon itself and the fold fitted into the formed hole, a knot may be tied in the suture end, or a pair or more of sutures can be combined together that can also be folded and a knot tied therein, for increasing the area of the suture that is for fitting in the formed hole. Which hole containing the suture or sutures is then filled with an adhesive material, that, when cured, com…
