Ceramic Implants For Knees

Stainless steel knee implants are also available however its use has mostly been taken over by other alloy implants.

Ceramic implants for knees.

These materials do not wear out easily but they will not last forever. This type uses a ceramic femoral component instead of metal or a metal component with a ceramic coating. Implants are made of metal alloys ceramic material or strong plastic parts. In saying this ceramic implants are more costly and can be more susceptible to fracturing since the material is brittle.

Zirconium alloy is used in a new ceramic knee implant. Ceramic knee replacement is also conducted in some parts of the world but it is not that successful and durable in the case of all patients. Titanium only implants are available for patients who are allergic to nickel but it is more difficult to obtain the highly polished surface that facilitates smooth motion with titanium than it is with cobalt chrome. This composite ceramic was developed to overcome the disadvantageous aging of zirconia and the relatively low fracture toughness of alumina.

The zirconium alloy is combined with an all plastic tibial component replacing the metal tray and plastic insert used in other knee replacements. People who are sensitive to the nickel used in metal implants might get the ceramic type. The knee replacement implant parts are made of metal medical grade plastic or ceramic. It also rides on a plastic spacer.

The metal femoral component curves around the end of the femur thighbone. The lower end of the femur. Types of knee replacement implants according to dr. Biolox delta ceramic knee.

Sedrakyan and his colleagues reviewed 118 published studies on hip and knee replacement devices they found that newer so called high tech versions including ceramic on ceramic hips and high flexion knees which promise the ability to move the knee more deeply and fluidly weren t any more effective than older products and that some were more often associated with the need for revision surgery surgery to correct a complication of surgery. While some people may have knee replacements that may last for decades some may require a second surgery called revision knee replacement surgery just a few years later. Up to three bone surfaces may be replaced in a total knee replacement.
