The invention relates to a special anchor fixing by pressure tendon grafts in chirurgical operations of cruciate knee ligaments. This plug bears three rings furnished with small teeth, an internal hole-screw and an oblique-cut head portion. At the insertion of the screw, the fissure of the anchor divides the anchor's body into two parts separated from each other. Due to the oblique cut of the head portion, the one part is shorter than the other and bears a bore leaving passage to the tendon. Screw threads and rings exist at both parts while the teeth of the rings are adapted to the section carrying the bore. |
