For years, orthopedic surgeons have cautioned knee replacement patients with the same warning - any implant can fail after years of use, and if that happens, it has to be revised. While that message is still true, the likelihood of a patient's knee implant failing due to normal wear has been dramatically reduced thanks to VERILASTTM Knee Technology, which is now being offered by surgeons at the Glendale Adventist Orthopedic Center.
Made up of three main parts, all total knee implants consists of a plastic insert positioned between two metal components. Over time, the movement of the metal component sliding against the plastic insert can wear down the plastic and cause it to fail. In some cases, tiny particles of the plastic can accumulate in the joint resulting in a condition known as osteolysis, or the softening of the bone around the joint. When this happens, the implant may shift or loosen, which leads to pain and instability in the joint.
Unlike other knee implants, made from cobalt chrome metal and a high-density plastic, VERILAST Technology is made from a proprietary metal alloy called OXINIUMTM Oxidized Zirconium and a highly cross-linked polyethylene. By combining these two low-friction materials, a knee implant with VERILAST Technology can significantly reduce the kind of wear that can cause an implant to wear out before its time. In fact, a VERILAST knee implant may last for up to 30 years of wear.
Other key advantages of VERILAST Knee Technology include:
- The surgeon uses the same implants and instrumentation they always have, so there is no learning-curve with this new technology
- It's hypoallergenic -- OXINIUM contains virtually no nickel or chromium - two metals that can cause problems for patients who have metal sensitivity
- Implants made with OXINIUM weigh 20% less than knee implants made from traditional metal alloys (cobalt chrome)
