Unlike other implants that are only available with cobalt chrome for their metal femoral components, the JOURNEY◊ II Active Knee implant can also be made with a proprietary metal alloy called OXINIUM◊ Oxidized Zirconium. While cobalt chrome has been used successfully for years, laboratory tests have shown that the "ceramicized" OXINIUM metal alloy is twice as hard as cobalt chrome and can be twice as resistant to the type of scratching that can cause implant wear. First introduced in 1997, OXINIUM implants have been used in more than 1 million surgeries around the world.
And since each implant is a combination of metal and plastic, JOURNEY II implants also use a harder, highly cross-linked polyethylene known as XLPE for the plastic insert.
Working together, these materials form a bearing surface combination known as VERILAST Technology, which is unique to global medical device maker, Smith+Nephew.
