Method of preparing suture anchor using suture and prepared suture anchor

A method of preparing a suture anchor using a suture, comprising:

• a first step (A) of bending a pair of first sutures having biological compatibility on a human body into a “U”-shape;
• a second step (B) of, after the first step (A), crossing a first end and a second end of the pair of first sutures bent into the “U”-shape into an “X”-shape to form an open space portion at a front portion and a loop space portion at a rear portion;
• a third step (C) of, after the second step (B), using a separate knitting tool, passing the tool through the loop space portion and then putting the tool into the open space portion from a lower side of the “X”-shape to hook the first end, pulling the tool rearwards, and further pulling rearwards the tool being in a state of passing through the loop space portion to form a knot;
• a fourth step (D) of, after the knot is formed by performing the third step (C), repeating the second step (B) and the third step (C) several times to form another knot in a predetermined length by continuing rearward from the previous knot,
• a fifth step (E) of, after the fourth step (D), cutting the knitted first sutures as a predetermined length and bonding the cut portion at the same time so that the cut portion is not untied, thereby forming a plurality of knitting members having the predetermined length;
• and
• a sixth step (F) of, after the fifth step (E), sewing a predetermined number of second sutures that attach a soft tissue such as a damaged joint membrane, a cartilage, a muscle, or a ligament to a bone by sewing between one knot and another knot of the knots in a longitudinal direction of the plurality of knitting members having the predetermined length.
