An attachment device for use in an implantation system which includes a prosthetic ligament (21), in order to guide the ligament to a required position in a bone tunnel, formed in a bone joint (10) between two adjacent bones (11, 12), and to anchor one end of the ligament, said device comprising: an elongate guide element (25, 125) which is manipulatable between a pulling position in which its longitudinal axis extends generally parallel to the pulling direction and an anchoring position in which its longitudinal axis extends transversely of the pulling direction; a connecting loop (27, 129) of flexible and implantable material which is connected, or connectable, at one end to the guide element (25, 125) and at its other end is connectable to one end of the prosthetic ligament (21) to be implanted, said loop being assembled from a fibre bundle of twisted yarn; connecting apertures (26, 126) formed in the guide elements (25, 125) which permit the loop (27, 129) to be connected thereto; and connecting means (26, 127) provided on the guide elements (25, 125) to permit pulling means (22, 128) to be connected to the element in order to pull the guide element, and trailing implantation system connected thereto, through the bone tunnels with the guide element orientated so that its longitudinal axis extends generally parallel to the pulling direction until the element emerges from the mouth at one end of one of the tunnels, whereby the guide element is manipulatable by the pulling means so as to overlie the mouth and thereby anchor one end of the implantation system.
