Which materials are most commonly used for joint replacements?
The metals commonly used include cobalt-chromium, titanium, zirconium, and nickel. Metal-on-plastic is the least expensive type of implant and has the longest track record for safety and implant lifespan. New implants are continually in development to make these implants last as long as possible.
What materials do they use for hip replacement?
Materials Used in Hip Implants
- Metal-on-Polyethylene: The ball is made of metal and the socket is made of plastic (polyethylene) or has a plastic lining.
- Ceramic-on-Polyethylene: The ball is made of ceramic and the socket is made of plastic (polyethylene) or has a plastic lining.
What is the most common material used in hip replacement?

What material do they use for knee replacement?
Implant Materials The metal parts of the implant are made of titanium or cobalt-chromium based alloys. The plastic parts are made of ultra high molecular weight polyethylene. Some implants are made of ceramics or ceramic/metal mixtures.
How long do ceramic hips last?
How long does a ceramic hip last? On average, hip replacements last 20 to 25 years before repair or replacement. In one study , only 4.4 percent of people who received a hip replacement required revision surgery in the first 10 years after surgery. About 15 percent required revision by the 20-year mark.

What kind of material is used to repair laminate?
Bonded external doublers are often used to perform repairs to lightly loaded thin laminate structures. This type of repair is especially common using wet lay-up materials. They may be room-temp or high-temperature cured, depending on the matrix resin system used.
