The metal-free BPK-S ceramic total knee replacement system proved to be a safe and clinically efficient alternative to metal implants in this short-term follow-up study.
Do all knee replacements contain metal?
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 is the best material for a knee replacement?
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 life span.
What is the safest knee replacement?
A TKR is now among the safest and most effective of all standard orthopedic surgeries. During a TKR, a surgeon removes the surface of your bones that have been damaged by osteoarthritis or other causes and replaces the knee with an artificial implant that is selected to fit your anatomy.

How long will an artificial knee last?
In 85% to 90% of people who have a total knee replacement, the knee implants used will last about 15 to 20 years. This means that some patients who have a knee replacement at a younger age may eventually need a second operation to clean the bone surfaces and refixate the implants.
Why is my knee so tight after surgery?
Arthrofibrosis is also known as stiff knee syndrome. The condition sometimes occurs in a knee joint that has recently been injured. It can also occur after surgery on the knee, such as a knee replacement. Over time, scar tissue builds up inside the knee, causing the knee joint to shrink and tighten.
What happens if you wait too long for knee replacement?
The leading cause of knee replacement is osteoarthritis. If you wait too long to have surgery, you put yourself at risk of experiencing an increasing deformity of the knee joint. As your condition worsens, your body may have to compensate by placing additional strain on other parts of the body (like your other knee).
How long do ceramic knee replacements last?
It is estimated that these knees last about 15-20 years. The new ceramic knee consists of a plastic tibial component and a metal (zirconium alloy) with a ceramic surface femoral component with a life expectancy of 20-25 years.
Can you kneel after a knee replacement?
About 60 to 80 percent of people report difficulty kneeling or an inability to kneel after a total knee replacement. There is currently no clinical evidence to suggest kneeling shortens the life of the prosthesis, but if you’re uncomfortable, you should avoid kneeling.
