The present invention relates to a polylactic acid-based suture anchor and a method for manufacturing the same. More specifically, the present invention relates to a polylactic acid-based suture anchor and a method for manufacturing the same. The polylactic acid-based suture anchor comprises a sharp tip part on an end portion, an annular protrusion part on an outer circumferential surface, and a hole into which a suture is inserted, and a surface of the anchor having 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, -TCP, and hydroxyapatite, and thus, the anchor has an increased contact area with soft tissues such as 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 stability and convenience of an operation. |
