GENESIS II

FEATURES
Materials
The primary materials used in the GENESIS II Total Knee System implant components include cobalt chromium molybdenum alloy (Co-Cr-Mo), titanium alloy (Ti-6Al-4V), and ultra-high molecular weight polyethylene (UHMWPE).

These materials were chosen for their clinically proven biocompatibility and mechanical properties.

The primary materials used for the GENESIS II instrumentation include 17-4 PH stainless steel and acetal copolymer. The femoral and tibial implants are offered with two different surface characteristics at the bone/cement/implant interface:
•a specially roughened surface
•a porous-coated surface
Design Features
Cobalt Chromium
• Minimum bone resection leaves anterior bone
• Same patellofemoral and tibiofemoral articular geometry as LDK and cruciate retaining femorals
• Varying anterior chamfer allows for deepened patellar groove without secondary preparation
• One up–one down interchangeability with posterior stabilized inserts
• Highly polished intercondylar box for reduction of wear debris
• Minimum bone resection leaves anterior bone Same patellofemoral articular geometry as LDK, cruciate retaining, and posterior stabilized femorals
• Allows for distal and posterior wedge augmentation
• Built-in long stem taper
• Built-up distal surface and anterior chamfer for revision cases
• Stem angled at 6°  Nonporous
• Allows for distal and posterior wedge augmentation
• Accepts conversion module for attachment of universal long stems

Fixation Features
Nonporous
• Box housing provides mediolateral stability
• Finned lugs for added mediolateral stability
• Grit-blasted surface
• Cement pocket Porous
• Flex-Lok pegs and finned lugs for added mediolateral stability and increased pullout strength
• Sintered CoCr beads
