Ceramic total knee components.

Thirty eight primary total knee arthroplasties tkas were performed on 34 patients using the metal free bpk s ceramic total knee replacement system with both the femoral and tibial components of an alumina zirconia ceramic composite. Ceramic parts are the least likely to react with the body. Furthermore the incidence of knee replacement in young and active patients is also increasing. Tkr systems was comparable.

The femur the long bone in the thigh the tibia the larger of the two bones in the lower leg and a patellar kneecap component which. Metal hypersensitivity in total knee arthroplasty. 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. 17 the patient suffered persistent pain and a reduction in the range of motion as well as swelling and patella immobility after tka with a metallic femoral component.

Ceramic femoral components performed comparably to traditional metallic designs. 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 femoral and tibial components are both made of ceramic. What is the cost of titanium knee replacement.

Bergschmidt p bader r mittelmeier w. Consequently knee replacements must be able to offer longer implant lifetime. In the majority of total knee replacements the surgeon places components of the implant also called a prosthesis on the joint surfaces of three bones that make up the knee joint. The femoral and.

Types of knee replacement. Thereby there was a case of revision of a total knee replacement with a metal femoral component using a ceramic implant because of metal hypersensitivity. In total knee replacement damaged bone and cartilage are removed and replaced with metal components that recreate the surface of the joint. Revision surgery using a ceramic femoral component a case report.

Current research is focusing on new materials and ceramic can play an important role in increasing the lifetime of the components. Hypersensitivity introduction total knee replacement tkr is an effective treatment for degenerative knee joints 1 5 improvements in. Revision total hip arthroplasty due to pain from hypersensitivity to cobalt chromium in total hip arthroplasty. In rare cases they can shatter under heavy pressure into pieces that must be removed by surgery.

In the us the approximate cost for a total knee replacement can amount to 49 500 while in the uk the cost can be around 24 000. The aim of the study was to evaluate the safety and efficacy of a novel metal free ceramic total knee replacement system.
