| abstract |
The present invention relates to a polylactic acid-based suture anchor and a method for manufacturing the same and, more specifically, to a polylactic acid-based suture anchor and a method for manufacturing the same, wherein the polylactic acid-based suture anchor comprises a sharp tip part on the end portion, an annular protrusion part on the external circumferential surface, and a hole into which a suture is inserted, and a surface of the anchor has a fine pattern formed thereon, in which first regions of polylactic acid alternate with second regions of at least one selected from the group consisting of polyglycolic acid, a copolymer of polylactic acid and polyglycolic acid, β-TCP, and hydroxyapatite, so that the anchor has an increased contact area with soft tissues (joint membranes, cartilages, muscular ligaments, tendons, etc.) due to fine bumps formed on the surface of the anchor, thereby firmly fixing the suture and improving the stability and convenience of an operation. |
