Definitions

  • Metal alloys have previously been used for the femoral and tibial components of prosthetic knee joints and polyethelene has been used as a material for the insert arranged therebetween.
  • the bearing surfaces used in any such hard on soft articulation may create wear debris which is a major cause of osteolysis and implant failure. Lack of lubrication on the articulating surfaces of a prosthetic joint may also lead to joint failure.
  • patients with prosthetic knees are often restricted in activity to that of low demand on the prosthetic device. Younger patients sometimes delay having surgery due to the short lifespan of artificial joints. While it may by possible to overcome these difficulties by using harder wearing biomaterials, the design of artificial knee joints may not necessarily facilitate use of such materials.
  • said curved articular surface of the tibial component is adapted to facilitate translation of the insert.
  • the articular surface 56 of the tibial component 14 is adapted to cooperatively engage and move with respect to the matched insert 16.
  • the articular surface 56 retains the convex shape of the apical portion of a sphere, the radius of which approximates that of the distance from the knee to the ankle of the patient.
  • the radius of curvature is, for example, greater than R 1 and R 2 .
  • the lateral articular surface 55 is less than the medial articular surface 57.
  • the articular surface 56 of the tibial component 14 is shaped to cover the entire contact area of the bone.
  • the raised section increases the contact area with the femoral component 12 whilst avoiding soft tissue impingement.
  • the insert also includes:
