What is the Stryker Triathlon knee made of?
The Triathlon Tritanium Metal-Backed Patella* features Stryker’s Tritanium 3D porous metal technology, made from commercially pure titanium, on the metal underside of the patella. > The Triathlon Tritanium Metal-Backed patellar components* are available with conventional polyethylene.
What is a Triathlon knee replacement?
The Triathlon knee system from Stryker is a popular total knee replacement. The polyethylene used in the TKR is from the X3 Stryker modern polyethylene range. The Triathlon knee replacement also has shortened and flared posterior condyles designed to allow a potential 150 degrees of flexion.
How much does a Stryker knee cost?
Stryker is launching its Triathlon total knee on its Mako robotic system, reportedly priced at $1 million, at a time of bundled payments and cost consciousness in joint replacement procedures.
What metal is used in Stryker knee replacement?
There are many knee replacement systems manufactured by Stryker, and each system is made from metals and components specific to that system. While cobalt-chromium and titanium are the most common, there are several other components that can be used to make the prosthesis.
What is the best age to have a knee replacement?
Knee replacement surgery isn’t typically recommended if you’re younger than 50. While recommendations for surgery are based on a patient’s pain and disability, most patients who undergo a total knee replacement are age 50-80. Why? Knee replacements are not as durable as your own knee and eventually wear out.
Can you wait too long for knee replacement surgery?
Unfortunately, many people wait too long to get knee replacement surgery. One study found that up to 90% of individuals in need of a knee replacement wait too long—often two or more years after the point at which they were considered a viable candidate for joint replacement.
What muscles are cut in a total knee replacement?
Traditional total knee replacement entails cutting into the quadriceps tendon, which connects the large quadriceps muscle group on the front of the thigh to the kneecap. The surgeon then moves the kneecap out of the way to access the arthritic joint.
What is replaced with a total knee replacement?
During a total knee replacement, the end of the femur bone is removed and replaced with a metal shell. The end of the lower leg bone (tibia) is also removed and replaced with a channeled plastic piece with a metal stem.
What is the best 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.
What are the disadvantages of a knee replacement?
Disadvantages. Possible disadvantages of knee replacement surgery can include replacement joints wearing out over time, difficulties with some movements and numbness. We now know that knee replacements aren’t so likely to be effective in the early stages of arthritis.
Is robotic knee surgery better?
Yes — robotic surgery has been shown to deliver better results vs. traditional knee replacement. Studies have shown surgeries performed with robotics offer more accurate results. The less trauma on the bone and tissue, the better the results, and robotic assistance allows for precision that reduces traumatic areas.
How long do artificial knees 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.
What is the most commonly reported problem after knee replacement surgery?
Knee replacement surgery can result in physical complications ranging from pain and swelling to implant rejection, infection and bone fractures. Pain may be the most common complication following knee replacement.
Can you get an MRI with 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 metal is used in a total knee replacement?
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. Whether metal or ceramic, implants weigh between 15 and 20 ounces, depending on the size selected.
