Ceramic Knee Replacement Vs Metal

The goal with any bearing surface is the bigger head with less wear rate.

Ceramic knee replacement vs metal.

However ceramic joint prostheses can make a squeaking noise when you walk. Metal on metal leads to an unknown issue of increased ions within blood stream. In most cases each component is built from titanium cobalt chromium alloys or a titanium and cobalt mixed metal. The replacement knee joint is comprised of a flat metal plate and stem implanted in your tibia a polyethylene bearing surface and a contoured metal implant fit around the end of the femur.

1 there are few studies comparing types of prostheses and even fewer that are not funded by device makers themselves. Due to this lack of research there is no. I am not sure if my ligaments and muscles can support the prothstesis or not. All knee replacements partial or total will have parts made of a few different materials likely metals and plastic.

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. Because the knee implant has a flatter bearing wear. The use of components made from metals and polyethylene allow for optimum articulation or joint mobility between the joint surfaces with little wear. Most prostheses are made from a combination of metal and plastic parts but a surgeon might also use components that are all metal all ceramic or ceramic and plastic.

Ceramic on ceramic has the lowest wear rates but there have been issues of squeaky joints and cracking. The femoral and tibial components are both made of ceramic. The aim of the study was to evaluate the safety and efficacy of a novel metal free ceramic total knee replacement system. The review check and the ratings will further ensure that the right product is being chosen before going ahead with the knee replacement surgery.

Before selecting a titanium knee replacement or a ceramic knee replacement a background check of the products and the knee implant manufacturers needs to be done. Artificial replacement parts can be made of strong plastic metal or ceramic. So my choice is still ceramic on polyethyelene. In rare cases they can shatter under heavy pressure into pieces that must be removed by surgery.

Ceramic parts are the least likely to react with the body. What are some names of ceramic tkr total knee replacement devices materials for non constraint semi and constraint. 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.
