What is oxinium technology?
What is oxinium technology?
OXINIUM material—a metal alloy with the surface transformed to ceramic using a patented process—has proven to be a superior metal for use in hip and knee implants due to its reduced friction and increased resistance to scratching and abrasion.
How long do Smith and Nephew knees last?
30 years
“Together, they yield virtually indiscernible wear. After performing wear simulator testing of the knee replacements over three continuous years, we have confirmed that this Smith & Nephew knee replacement made with VERILAST technology, under normal circumstances, is expected to last for 30 years,” he said.
Is there a ceramic knee replacement?
Ceramic Knee Offers Pain Relief for Younger Patients. A new ceramic total knee replacement is now available after two years of clinical trials at Hospital for Special Surgery. The new knee offers relief to younger patients in their late 40s-early 50s who need total knee replacements.
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 is the best knee replacement for an active person?
When possible, use biologic knee replacement procedures —such as articular cartilage paste grafting, combined with meniscus replacement—to rebuild the knee naturally. If you have bone-on-bone disease, past the point where biologic replacement techniques can work, replace the affected area with artificial components.
Are screws used in total knee replacement?
As this study demonstrates long survival time and low complication rates for screws in cementless total knee replacement surgery; we recommend using screws for cementless tibial components particularly in young patients with good bone quality and stock to increase initial stability.
What is Oxinium knee replacement material?
After the knee replacement, the prosthesis material used undergo cyclical loading and stress during the usage of knee in daily activities. Oxinium is a patented ceramic metal alloy – made of zirconium alloy metal substrate consisting of 97.5% Zirconium and 2.5% of Niobium.
Does TKA with Oxinium femoral components increase the risk of revision?
In these patients, TKA with Oxinium femoral components had a higher rate of revision. Younger patients preferentially received Oxinium femoral components. The revision risk was not affected by patellar resurfacing or nonresurfacing.
What is Oxinium used for?
Product Information. More than a decade ago, Smith & Nephew introduced OXINIUM ◊ Oxidized Zirconium. This patented metal alloy is available for many of our knee and hip implant systems. The combination of hardness, smoothness and scratch-resistance makes it a superb choice for hip and knee implants.
How long do Oxinium knee prosthesis last?
Oxinium knee prosthesis are wear and abrasion resistant and thus last much longer as compared to traditional prosthesis implants of cobalt-chrome. The usual tested durability of Oxinium prosthesis is around 35 years. This is best suited for younger patients who had to undergo revision knee replacement after 15-20 years.
