Improving anatomic implant fit
The ANTHEM◊ Knee System is a total knee prosthesis with advanced femoral and tibial anatomic design, developed with the intention to:
- Promote improved anatomic implant fit for patients 1
- Enhance femoral and tibial anatomic implant fit
- Anthropometrically optimize low profile femoral anterior flange to reduce incidence of overhang
- Include bone conserving femoral PS box design, preserving intercondylar notch bone stock
- Include an anatomic asymmetric tibial baseplate design with shorter, medialized tibial stem to suit a wider range of anatomies
Advanced technology
- The ANTHEM knee system is based upon trusted design pedigree incorporating clinically advanced technology such as the tibio-femoral articulation and patello-femoral function equivalent to the GENESIS◊ II Total Knee System.
- Equivalent implant tibio-femoral kinematics and articulation to the clinically successful GENESIS II design 1,4,5
- Patella Friendly S-curve funnels patella to facilitate tracking toward midline in deep flexion
- Hi Flexion insert accommodates up to 155 degrees of flexion
- Tibial base plate with patented DURAHONE◊ Advanced Finishing technology surface finish to reduce surface roughness and to decrease micromotion minimizing backside wear
- The ANTHEM Knee System is compatible with all GENESIS and LEGION◊ tibial inserts and tibial baseplates for addition of stems and wedges for complex primary procedures
Efficiency through intelligent design
- The ANTHEM Total Knee System has been developed in conjunction with leading surgeons from the Emerging Markets and Europe. The ANTHEM Knee System can be used with the ORTHOMATCH◊ Universal Instrument platform, creating efficiency through intelligent design, providing tangible value for surgeons, patients and healthcare providers.
- Efficient, Intuitive and Effective system providing streamlined and reproducible surgical flow
- State of the art low weight, durable materials with reduced instrument footprint to reduce hospital costs
