Total Knee System

ANTHEM Total Knee System

Overview

The ANTHEM Total Knee System was designed to provide an advanced and anatomically fit prosthesis and instrumentation system.

The ANTHEM knee system is a total knee prosthesis with advanced femoral and tibial anatomic design to promote improved anatomic implant fit for all patients globally.1

  • 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, which exhibits a 98% survivorship at 15 years.2,3

  • The ANTHEM Total Knee System coupled with ORTHOMATCH Universal Instrumentation platform has been developed in conjunction with leading surgeons from Emerging Markets and Europe providng benefits by creating efficiency through intelligent design which translates into tangible value for surgeons, patients and healthcare providers.

Design and Technology

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

Indications

Indications for ANTHEM Total Knee Replacement

 

  • Rheumatoid arthritis.
  • Post-traumatic arthritis, osteoarthritis, or degenerative arthritis.
  • Failed osteotomies, unicompartmental replacement, or total knee replacement.
  • Posterior stabilized knee systems are designed for use in patients in primary and revision surgery, where the anterior and posterior cruciate ligaments are incompetent and the collateral ligaments remain intact.
