Ceramic Vs Metal Knee Replacements

All knee replacements partial or total will have parts made of a few different materials likely metals and plastic.

Ceramic vs metal knee replacements.

Why metal on metal hip replacements are made to fail. All metal implants originally were developed to provide longer lasting joint replacements for younger people but the traces of metal can cause inflammation pain and possibly organ damage. The most common metal ions found in knee replacement implants that can cause hypersensitivity include nickel cobalt and chromium. Ceramic on ceramic has the lowest wear rates but there have been issues of squeaky joints and cracking.

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. What are some names of ceramic tkr total knee replacement devices materials for non constraint semi and constraint. 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. The review check and the ratings will further ensure that the right product is being chosen before going ahead with the knee replacement surgery.

Over the last two decades the number of total hip replacements being performed each year has steadily increased in the united states. The aim of the study was to evaluate the safety and efficacy of a novel metal free ceramic total knee replacement system. Because the knee implant has a flatter bearing wear. The goal with any bearing surface is the bigger head with less wear rate.

Metal on metal implants may be considered only for young active men because they may last longer than other materials. In most cases each component is built from titanium cobalt chromium alloys or a titanium and cobalt mixed metal. The materials used for hip and knee replacements are quite similar. Artificial replacement parts can be made of strong plastic metal or ceramic.

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. 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. The use of components made from metals and polyethylene allow for optimum articulation or joint mobility between the joint surfaces with little wear. So my choice is still ceramic on polyethyelene.

Is to remove the implant and replace the knee with a special implant made of ceramic or titanium.
