摘要

Tibial part of a knee prosthesis, in particular unicompartmental, comprising a tibial plate having a lower (or distal) face (3) delimited by a peripheral edge (6) having at least one lateral section (9), and from which protrudes at least one anchoring stud (4; 5) intended to be anchored in the tibia, the at least one stud (4; 5) comprising at least one part (14) forming a rod and a part (15) forming a head, the rod part and the head part defining between them an interface (25) which corresponds to the cross section of the stud, called the anchoring section, which is located at the points (22) of the lateral surface of the stud which are the outwardly of the stud, characterized in that the cross section at the base of the rod and the anchoring section are mutually offset, the center (21) of the anchoring section (25) being further from the section (9) lateral to the plate as the center (23) of the section (dl) transverse to the at the base of the stem.
