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).

Anchoring element for anchoring a ligament transplant in a channel in a bone, comprising
- 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 said channel, said body serves for clamping said ligament transplant within said channel, wherein
- said body has an outer flexible sheath filled with a plurality of particles having a low compressibility, said particles within said outer flexible sheath allowing said body to accommodate to a shape of said intermediate space between said ligament and said channel.
A method for anchoring a ligament transplant in a channel in a bone, with an anchoring element comprising the steps of
- providing a channel within a bone,
- inserting into said channel a ligament transplant having a diameter smaller than a diameter of said channel,
- introducing an anchoring element into an intermediate space between said ligament and said channel for clamping said ligament transplant, said method comprising the steps of
- providing an anchoring element having an outer flexible sheath filled with individual particles which are of low compressibility,
- accommodating a shape of said deformable anchoring element to a shape of said intermediate space between said ligament and said channel when inserted into said intermediate shape.
