Definitions

  • the invention relates to a knee joint replacement with a femoral component and a tibial component, each having a front side forming the joint and a rear side facing the bone and having a polyethylene (PE) liner.
  • PE polyethylene
  • the current state of the art for replacement of the knee joint provides for over 90% cemented endoprostheses.
  • the bone cement adheres very well to the strongly roughened surfaces of the metallic endoprostheses (CoCrMo or Ti alloys), but dissolves over time due to the action of the aqueous environment in the human body on the component (so-called "debonding")
  • Micro-movements of the knee endoprostheses on the bone cement quiver and the progressive subcritical crack growth of the bone cement due to the dynamic loading of the joint shatters the bone cement over time, resulting in abrasion particles which enter the surrounding tissue and also in the sliding surface of the bone
  • the resulting bone cement as well as PE abrasion usually leads to a biological reaction of the surrounding tissue resulting in local inflammation and osteolysis (regression of the bone) to aseptic loosening of the Implants can lead.
  • This mechanism is indispensable for cemented knee endoprostheses and also explains why the average life of a cemented knee joint endopros
  • Cementless knee endoprostheses represent an alternative with great potential for longer prosthesis service life.
  • Metal knee joint endoprostheses that are frequently provided with a likewise metallic osseointegrative coating, which is the direct ingrowth of the knee joint endoprostheses, are currently established on the market Bone in the implant surface allows.
  • Such metal-free knee joint components combine the advantages of a biocompatible, allergy-friendly material and low wear of the sliding pair with excellent osseointegration.
  • An inventive knee joint replacement with a femoral component and a tibial component, each with a front side forming the joint and a back side facing the bone and with a polyethylene (PE) liner is characterized in that the femoral component and the tibial component consist of a full ceramic and with porous osseointegrative bone-facing Rear of both components.
  • the femoral component and the tibial component are each made of a ceramic sintered shaped body, wherein the sintered shaped bodies have a porous layer on their rear side facing the bone.
  • the porous bone-facing rear side is formed by applying a ceramic slip and spacers (pore-forming agent) on the base body (component) in the green state. About the sintering process, a compound of the layer is achieved with the body. Burning out the placeholders during sintering creates an open - pored structure with a fissured surface, which advantageously supports bone ingrowth and ingrowth. See also EP 1 268 364 A1.
  • the ceramic slip consists of the same material as the ceramic base body.
  • the complete implant, including the coating is completely free of metals and advantageous in terms of allergic reactions.
  • the porous bone-facing rear side is formed by foaming a ceramic slip and spacers (pore formers) on the base body (component) in the green state.
  • the porous bone-facing rear side can also be formed by joining a dense molding with a porous ceramic molding in the sintered state.
  • the porous molding can be made by foaming ceramic Slurry and sintering or infiltration of a porous carrier material with slip and sintering arise.
  • the joining is preferably carried out by soldering or gluing. This type of coating in combination with a ceramic base body is metal-free advantageous in terms of allergic reactions.
  • the integrated porous osseointegrative bone-facing back may also be formed by 2K injection molding (dense phase and porous or pore-forming phase) and sintering. This type of coating in combination with a ceramic base body is metal-free.
  • the porous bone-facing rear side can preferably be given additional functionality by further coating, such as a higher rate of integration or antibacterial effects. Integration speed is the time of ingrowth with the bone. This can preferably be achieved with Biogläsern, Hydroxilapatit, functionalized proteins or hydrogels.
  • the porous bone-facing rear side is formed by applying a porous metallic biocompatible layer on the already sintered ceramic base body (see EP 1 052 949 B1).
  • Figure 1 shows a total ceramic knee joint endoprosthesis consisting of femoral component 1, a tibial component 2 and ziwscheneaudem polyethylene (PE) liner 3 in the implanted state.
  • the porous bone-facing back is identified by the reference numeral 4.
