An attachment device includes an elongate guide element 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 to the pulling direction. A connecting loop of flexible and implantable material is connected, or connectable, at one end to the guide element and at its other end is connectable to one end of the prosthetic ligament to be implanted. The loop is assembled from a fibre bundle of twisted yarn. Connecting apparatus are formed in the guide elements which permit the loop to be connected thereto. Connector structure is provided on the guide elements to permit lines to be connected to the element in order to pull the guide element, and a trailing implantation system connected thereto, through 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 mount at one end of one of the tunnels, whereby the guide element is manipulatable by the lines so as to overlie the mouth and thereby anchor one end of the implantation system. |
