Modern Design For Optimal Results

The Freedom Knee® System was developed using advanced design engineering technologies and extensive clinical experience to address the anatomical, physiological and lifestyle needs of today’s patients.

The system’s significant design advances allow patients to achieve optimal high-flexion range of motion regardless of the several tibial component options chosen. This design approach provides surgeons with several unique component options that deliver proven successful, predictable, and reproducible results.


Freedom® Primary Knee

  • Over 11 years of worldwide usage with outstanding success
  • Multi-radius design with 7 radii accommodates changes in rollback in transition from walking to through deep flexion
  • Anterior flange design reflects bone-conserving design
  • 5-year published results1 conclude optimum TKA performance without:

– patient loss to follow-up
– related complications or component failure
– deterioration of the prosthetic composite

  • Offers multiple size options that feature dynamically proportioned M/L and A/P femoral components in CR and PS Options, along with stemmed tibia and ultra-congruent liner options.
