Ceramic Vs Metal Knee Replacements

Squeaking which has been reported in up to 8 of patients with ceramic on ceramic artificial joints is more of a nuisance than a safety issue but it s just one of a number of problems seen with the latest hip and knee replacement devices according to art sedrakyan md phd associate professor in health care policy and research at weill.

Ceramic vs metal knee replacements.

Is to remove the implant and replace the knee with a special implant made of ceramic or titanium. The review check and the ratings will further ensure that the right product is being chosen before going ahead with the knee replacement surgery. Metal on metal implants may be considered only for young active men because they may last longer than other materials. The most common metal ions found in knee replacement implants that can cause hypersensitivity include nickel cobalt and chromium.

Because the knee implant has a flatter bearing wear. The goal with any bearing surface is the bigger head with less wear rate. So my choice is still ceramic on polyethyelene. 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.

Over the last two decades the number of total hip replacements being performed each year has steadily increased in the united states. Hip and knee replacement surgery involve replacing the worn out bone and cartilage lining your hip or knee joint with new implants that are composed of materials such as ceramic metal and plastic. All knee replacements partial or total will have parts made of a few different materials likely metals and plastic. In most cases each component is built from titanium cobalt chromium alloys or a titanium and cobalt mixed metal.

What are some names of ceramic tkr total knee replacement devices materials for non constraint semi and constraint. Artificial replacement parts can be made of strong plastic metal or ceramic. I am not sure if my ligaments and muscles can support the prothstesis or not. 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.

The use of components made from metals and polyethylene allow for optimum articulation or joint mobility between the joint surfaces with little wear. Metal on metal leads to an unknown issue of increased ions within blood stream. Ceramic on ceramic has the lowest wear rates but there have been issues of squeaky joints and cracking. The materials used for hip and knee replacements are quite similar.

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.
