Abstract
In a tibial portion of a knee joint endoprosthesis with a securing shank (10) to be inserted into the medullar cavity of the tibia, which, on one end, is provided or not with a tibia condyle terminal plate for the attachment of the articular parts of the prosthesis, the securing shank (10), in order to achieve a firm fit of the implant after the implantation, comprises a cylindrical sleeve (11) that is insertable into a cylindrical slotted drilled hole (201) of the tibia with an interior (12) accommodating the spongiosa nucleus (205) of the slotted drilled hole (201), and is fabricated from a metallic material or some other suitable, body-compatible material, while the securing shank (60) is disposed at a right angle to the terminal plate (20) extending parallelly to the horizontal or slightly inclined ostectomy area (206) (FIG. 1).
