However there is no clear clinical evidence that ceramic femoral components leading to less polyethylene wear would increase survivorship of total knee replacement so far.

The swedish knee arthroplasty register evaluated in a 10 year period 2002 to 2012 3 102 revisions after primary tka using metallic femoral components. Consequently knee replacements must be able to offer longer implant lifetime. Bergschmidt p bader r mittelmeier w. Furthermore the incidence of knee replacement in young and active patients is also increasing.

Types of knee replacement. A total knee replacement implant consists of the femoral component and the tibial component made of metal and the spacer which is made of polyethylene.
