Abstract:
A joint prosthesis for permanent anchorage in the bone tissue at the joint end of a first articulatory part of a joint, especially a knee joint, in the human body, said joint defining a predetermined main articulation plane in which articulatory movements of said joint take place said joint prosthesis comprising:a flat, plate-like element having front and rear major faces, the rear major face adapted in use to engage with a complementary bone surface which presents the joint end or a part of the joint end of the first articulatory part after resection of the original joint end or a part of the original joint end, andat least one elongate fixture which extends along the plate-like element at a spaced distance therefrom and is attached to the rear major face of the plate-like element so as to allow the at least one elongate fixture in use to be located in healthy, relatively intact bone,wherein the plate-like element and at least one fixture are integrally formed into a main body component prior to anchorage in the bone tissue, andwherein said at least one elongate fixture is so arranged relative to the plate-like element that on anchorage of the joint prosthesis in the bone tissue at the joint end of the first articulatory part said at least one elongate fixture is inclined at an angle relative to said predetermined main articulation plane.
