Is cobalt still used in knee replacements?
Typically made from cobalt-chromium as this material is scratch resistant and safe for use in total knee replacements. The majority of total knee femoral components are made out of cobalt-chromium with excellent long-term success rates.
Does cobalt cause dementia?
Chromium and cobalt toxicity may have caused permanent but unchanging brain damage in the patients, which in turn may have caused the cognitive problems. Alternatively, metal poisoning may have triggered early onset dementia in these patients.
Can you do an MRI on a knee replacement?
Yes. MRI scans of other parts of your body are safe after knee replacement. Although some old MRI scanning equipment may not be compatible with your prosthesis, the majority of MRI scanning equipment today is safe and compatible with knee replacement parts.
What is the latest technology for knee replacements?
This latest advancement in joint replacement surgery transforms the way knee replacements are performed. “The Mako system is a revolutionary tool to help joint surgeons be more precise in placing implants to achieve the most appropriate, balanced position possible,” explained orthopedic surgeon Harold Cates, MD.
How long does it take to walk after a full knee replacement?
You will probably be able to walk on your own in 4 to 8 weeks. You will need to do months of physical rehabilitation (rehab) after a knee replacement. Rehab will help you strengthen the muscles of the knee and help you regain movement.
What is the best material for knee replacement?
What is the best material for knee replacement? Typically made from cobalt-chromium as this material is scratch resistant and safe for use in total knee replacements. The majority of total knee femoral components are made out of cobalt-chromium with excellent long-term success rates.
What kind of metal is used for knee replacement?
Titanium alloys are also used in some knee replacement systems, and these alloys commonly contain aluminum and vanadium. Due to the density and elastic nature of titanium and its alloys, some risks associated with knee replacement may be reduced. Other, lesser used materials include tantalum, polyethylene and zirconium.
Is cobalt chrome an alloy?
Cobalt-chrome or cobalt-chromium ( CoCr) is a metal alloy of cobalt and chromium. Cobalt-chrome has a very high specific strength and is commonly used in gas turbines, dental implants, and orthopedic implants. Co-Cr alloy was first discovered by Elwood Haynes in the early 1900s by fusing cobalt and chromium.
What are the types of knee replacement implants?
The femoral component is generally made of metal and curves around the end of the femur (your thighbone).
