Titanium Niobium Nitride with vitamin E blended polyethylene which significantly reduces wear of implant.
VITAMIN E POLY
An appropriately cross-linked polyethylene material, a knee- specific formula, is blended with vitamin E and formulated to reduce long – term wear.
Re-melting Not Required
In the case of most highly cross- linked polyethylene, an anneal or re-melt step occurs following cross-linking to link free radicals (created by the irradiation). Annealing or remelting polyethylene can reduce mechanical strength properties. Vitamin E neutralizes the negative effects of free radicals, an anneal or re-melt step is rendered unnecessary. In a material yield strength test, compression molded samples and e performed statistically the same, while a highly cross linked re- melted sample exhibited a 12% drop in yield strength. Vitamin E is blended right into the resin, assuring complete homogeneous distribution. Also vitamin E, a non-irritant is the most effective naturally occurring anti-oxidant in the human body.
Maximum Mechanical Strength
The impact of oxygen exposure to Vitamin-E sample was evaluated in accelerated aging tests. Un-aged and aged Vitamin-E sample yielded the same result during yield strength testing. Impact testing for the aged Vitamin-E sample actually revealed slightly better results than un-aged sample, indicating that oxygen has no negative impact on Vitamin-E. Titanium Niobium Nitride -coated protection for maximum performance.
It is 4 to 5 times harder than conventional CoCr implants has negligible metal ions (Chrome & Nickel)) so a perfect choice for metal allergy patients. Combination of Armor coat femoral component with Vit E Poly gives 57% reduction in wear, so long life of implant.
