Klassic® FEMUR WITH
AURUM® TECHNOLOGY

AURUM® FOR EVERYONE
The New Gold Standard™

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. 

PRODUCT FEATURES

FRONT

BACK

9° DOUBLE Q-ANGLE
The femur features a patented trochlear groove that allows optimal patellar tracking along a 9° double Q-angle on both left and right anatomy, while retaining a neutral outside profile of the anterior flange.
AURUM® TECHNOLOGY

The Aurum® Femur 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.
ANATOMICALLY OPTIMIZED
TIBIAL BASEPLATE

The tibial baseplate is designed to optimally cover the tibial plateau using a universal geometry.
CRUCIATE RETAINING AND
CRUCIATE SACRIFICING TIBIAL INSERTS
Both a deep-dished Ultra-PS® Insert and a standard CR/Congruent Insert are compatible with the Klassic CR Femur.
4° SWEPTBACK KEEL
The sweptback keel 4° of posterior slope.
MODULAR KEEL INTERFACE
The sweptback keel offers modularity to allow for stem extensions and future augments.
CONFORMING CONGRUENCY
The M/L edges of the tibial baseplate and inserts have matching conforming geometry to provide consistent polyethylene thickness all the way to peripheral edges.
BASEPLATE CEMENT POCKETS
Recessed pockets combined with a grit blast finish for optimal cement adhesion.
PERIPHERAL PEGS
Four peripheral pegs for initial mechanical fixation and rotational stability.
FEMUR CEMENT POCKETS

Recessed pockets combined with a grit blast finish for optimal cement adhesion.
AUTOMATICALLY OPTIMIZED
GEOMETRY


Anatomically tapered posterior condyles, a proportional AP/ML ratio, and an optimized bone-covering geometry that minimizes
potential lateral overhang.

AURUM® TECHNOLOGY | OUR COMMITMENT TO REDUCING COBALT CHROME IN ORTHOPEDICS

AURUM® PROCESS

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.

AURUM® vs. COBALT CHROME

STRENGTH

The Klassic® Femur with Aurum® Technology demonstrated equivalent fatigue strength to the traditional CoCr Klassic® Femur at 10,000,000 cycles of loading.13

WEAR

The Aurum® process offers significantly improved wear-resistance, abrasion-resistance, and surface hardness when compared to cobalt chrome. Mode I wear testing was performed on pristine Aurum® and cobalt chrome femurs against conventional polyethylene (UHMWPE) to 5,000,000 cycles. The femurs were then scratched with sandpaper and run for an additional 3,500,000 cycles. Aurum® Femurs showed significantly less wear than cobalt chrome (CoCr)
femurs under Mode III wear testing.12

HARDNESS

Increased surface hardness makes Aurum® implants more resistant to scratches and wear than cobalt chrome.
