Abstract: A method for reattaching a detached tissue to a hard tissue includes operation in which a suture anchor having a first stitch and a second stitch is provided, wherein the first stitch is divided into a first strand and a second strand, and the second stitch is divided into a third strand and a fourth strand. The suture anchor is fixed on a hard tissue. The first strand, the second strand, the third strand and the fourth strand pass through a detached tissue. A bioinductive patch is provided, wherein the bioinductive patch includes a patch body and a button. The first strand and the third strand pass through the patch body and a first suture hole of the button, and the second strand and the fourth strand pass through the patch body and a second suture hole of the button. The second strand and the third strand are knotted to form a first strand node, and the first strand node presses the bioinductive patch and the detached tissue tightly onto the hard tissue.
