A fixation device for a graft, the device including: an elongate body circumscribed by the following outer surfaces: a first end surface and a second end surface opposite the first end surface defining an overall length of the elongate body in between, a lower surface and an upper surface opposite the lower surface defining an overall height of the elongate body in between, and a first side surface and a second side surface opposite the first side surface defining an overall width of the elongate body in between; a transverse passage for retaining a graft retainer element, the transverse passage extending from the first side surface to the second side surface; a first aperture extending into the first end surface, and a second aperture extending into the second end surface; a longitudinal passage extending through the elongate body from the first aperture to the second aperture; and a suture having a trailing length and a leading length, the leading length extending through the longitudinal passage; and characterized in that the fixation device further comprises a graft retainer element located within the transverse passage, such that the leading length of the suture extends across the transverse passage and over the graft retainer element; and in that the suture includes a stop at an intermediate position of the suture, the stop separating the leading length from the trailing length of the suture; wherein the stop abuts the first end surface of the elongate body when tension is applied to the leading length of the suture, so that the fixation device can be drawn in the direction of the leading length, the elongate body is rotated when tension is applied to the trailing length of the suture, and the suture can be extracted from the elongate body when further tension is applied to the trailing length of the suture. an elongate body circumscribed by the following outer surfaces: a first end surface and a second end surface opposite the first end surface defining an overall length of the elongate body in between, a lower surface and an upper surface opposite the lower surface defining an overall height of the elongate body in between, and a first side surface and a second side surface opposite the first side surface defining an overall width of the elongate body in between; a transverse passage for retaining a graft retainer element, the transverse passage extending from the first side surface to the second side surface; a first aperture extending into the first end surface, and a second aperture extending into the second end surface; a longitudinal passage extending through the elongate body from the first aperture to the second aperture; and a suture having a trailing length and a leading length, the leading length extending through the longitudinal passage; and characterized in that the fixation device further comprises a graft retainer element located within the transverse passage, such that the leading length of the suture extends across the transverse passage and over the graft retainer element; and in that the suture includes a stop at an intermediate position of the suture, the stop separating the leading length from the trailing length of the suture; wherein the stop abuts the first end surface of the elongate body when tension is applied to the leading length of the suture, so that the fixation device can be drawn in the direction of the leading length, the elongate body is rotated when tension is applied to the trailing length of the suture, and the suture can be extracted from the elongate body when further tension is applied to the trailing length of the suture.
