The OXINIUM Oxidized Zierconium was first introduced by Smith & Nephew over a decade ago. This patented metal alloy features a combination of scratch-resistance, hardness, and smoothness, which makes it a superior choice for patients who require knee and hip replacements. Its reduced friction and increased resistance to abrasion and scratching make it an ideal metal for these kinds of surgeries. The OXINUM material can potentially last longer than other implants. This is due to the fact that the surface is transformed into ceramic. On top of that, its surface hardness is more than twice that of cobalt chrome. This allows for significant less wear than can be produced by traditional cobalt-chrome alloy.
