More particularly, the present invention relates to a polylactic acid based suture anchor comprising a tip portion sharpened at an end portion, an annular protrusion portion at an outer peripheral surface thereof, and a hole into which a suture thread is inserted, The surface includes a fine pattern in which a first region of polylactic acid and a second region of one species selected from the group consisting of polyglycolic acid, a copolymer of polylactic acid and polyglycolic acid,? -TCP, and hydroxyapatite are alternately formed, The anchors are formed by fine irregularities formed on the surface of the anchors to increase the contact area with soft tissues (joints, cartilage, muscle ligaments, tendons, etc.), so that the sutures can be firmly fixed and polylactic acid The present invention relates to a suture anchor and a method for manufacturing the same. |
