Definitions
- the invention relates to a knee joint prosthesis according to the preamble of claim 1.
- a knee joint prosthesis with a tibial component which is attached to the proximal tibia and a femoral component, which is attached to the distal femur and has condylar bearing sections that articulate with condylar bearing sections of the tibial component.
- this knee joint prosthesis consists of a patellar component which is attached to the patella and has a patellar bearing surface which touches an anterior plate section of the femoral component when the prosthetic knee joint is fully extended.
- the femoral component with the anterior plate section is a one-piece object made of a metal or a metal alloy such as a cobalt-chromium-molybdenum alloy, titanium or a titanium alloy.
- the patellar bearing surface is made of a plastic, e.g. B. Ultra high molecular weight polyethylene.
- Knee joint prostheses which have no patellar component. This is where the natural patella, i.e. H. the bone, directly an anterior plate section of the femoral component with the prosthetic knee joint fully extended.
- the invention has for its object to improve a knee joint prosthesis according to the preambles of claims 1 or 3 such that less wear occurs on the patellar bearing surface or the natural patella. - 2 -
- anterior plate section and the bearing surface of the patellar component consist of one of the following sliding pairings:
- the anterior plate section is advantageously designed as an insert in the femoral component.
- the object on which the invention is based is achieved in a second embodiment by the features of claim 3.
- the knee joint prosthesis has no patellar component.
- the natural patella i.e. H. the bone directly touches the anterior plate section of the femoral component.
- the ceramic in all its forms consists of aluminum oxide, zirconium oxide, mixed ceramic made of aluminum oxide or zirconium oxide or of other biocompatible ceramics or coatings. Further features of the invention emerge from the figures, which are described below. It shows:
- Fig. 1 shows schematically a knee joint prosthesis with a tibial component, a meniscus and a femoral component and
- FIG. 2 as a section the femoral component of FIG. 1 with adjacent patellar component.
- FIG. 1 schematically shows a knee joint prosthesis according to the invention with a tibial component 1 which is attached to the proximal tibia (not shown).
- This tibial component 1 has tibial bearing sections 4, which interact in an articulated manner via a meniscus 9 with condylar bearing sections 3 of the femoral component 2.
- the femoral component 2 has an anterior plate section 8, which in one embodiment cooperates with a patellar bearing surface of a patellar component which is attached to the patella, and in another embodiment directly with the patella, i. H. the bone, cooperates or serves as a sliding surface for this.
- FIG. 2 shows a section of the femoral component 2 according to FIG. 1 with an adjacent patellar component 5.
- the patellar component 5 has a bearing surface 7 which slides on the anterior plate section 8.
- the anterior plate section 8 is made of metal and the bearing surface 7 of the patellar component 5 is also made of metal.
- the anterior plate section 8 and the bearing surface 7 of the patellar component 5 are advantageously made of ceramic. Wear is almost impossible here.
- the plate section 8 is expediently designed as an insert in the femoral component 2. - 4 -
- the anterior plate section 8 is made of ceramic and the bearing surface 7 of the patellar component 5 is made of plastic, preferably polyethylene.
- the plate section 8 is expediently designed as an insert. The attachment of the insert in all embodiments can be done by gluing, shrinking, clamping, soldering, welding or other possible types of attachment.
- the anterior plate section 8 is a ceramic insert and the patella directly contacts the plate section 8.
- the ceramics used are preferably aluminum oxide, zirconium oxide, mixed ceramics made of aluminum oxide or zirconium oxide or other biocompatible ceramics or coatings.
