Optetrak Logic

Optetrak Logic® is an advanced approach to total knee replacement that introduces modern design features and intuitive instrumentation while building on the wisdom of a strong design lineage. This knee system provides logical solutions to the timeless challenges of knee replacement: longevity, efficiency, bone preservation and functionality.

  1. Hi-Flex® design allows controlled rollback for up to 145 degrees of flexion.1
  2. Deep, wide femoral groove and contoured femoral flange reduce strain in the retinaculum, allowing for more natural patellar tracking.2,3,4
  3. Optimized femoral/tibial congruency (a patented feature) reduces contact and polyethylene stresses.5
  4. Direct compression molded polyethylene minimizes wear and polyethylene debris.6
  5. Modular tibial components feature a 3-part locking mechanism to prevent insert motion and dislocation.7,8,9
