The Klassic® Femur with Aurum® Technology features the same patented geometry and articulation as the Klassic® Femur and offers a revolutionary ballistically bonded titanium nitride (TiN) surface to provide a premium implant without the deliberate addition of common metal sensitizers such as nickel, cobalt, and chromium.
This Master Class features a deep dive discussion about Aurum® Technology and its ability to deliver a viable alternative solution to Cobalt Chrome. See case examples illustrating the impact this technology has had on patients' lives, and learn why all large joint surgeons should be considering the addition of the Klassic® Knee with Aurum® to their case planning.
Aurum® uses a proprietary process to ballistically bond a five-micron thick titanium nitride coating to the titanium substrate. The result is a hardened surface that offers exceptional wear characteristics without cobalt chrome.11
Because the Aurum® IBED process is a physical process and not a chemical or thermal process, the temperature during bonding is below 400ºF. Ion beam enhanced deposition application utilizes kinetic energy versus heat, so the coating environment maintains a much lower temperature, preserving the integrity of TiN’s strength and hardness.
The Klassic® Femur with Aurum® Technology demonstrated equivalent fatigue strength to the traditional CoCr Klassic® Femur at 10,000,000 cycles of loading.13
Increased surface hardness makes Aurum® implants more resistant to scratches and wear than cobalt chrome.
The Aurum® Femur offers a revolutionary titanium nitride (TiN) surface that is ballistically bonded to a titanium substrate to provide a premium implant without the deliberate addition of common metal sensitizers such as nickel, cobalt, and chromium.
Mode I wear testing was performed on pristine Aurum® and cobalt chrome (CoCr) femurs against conventional polyethylene (UHMWPE) to 5,000,000 cycles. The femurs were then scratched with 400 grit sandpaper and run for an additional 3,500,000 cycles.
The calculated linear wear of UHMWPE on Aurum® femurs showed significantly less wear than CoCr femurs under Mode III wear testing.12
