Abstract: An anchoring element serves for anchoring a ligament transplant in a channel in a bone. The anchoring element has a body which can be brought into an intermediate space between an inner wall of a channel within a bone and a ligament transplant introduced into the channel. The body serves for clamping the ligament transplant in the channel. The body has an outer flexible sheath filled with particles which are of low compressibility, the particles within the outer flexible sheath allowing the outer flexible sheath to accommodate to a shape of the intermediate space between the ligament and the channel (FIG. 4).
