Freedom® Porous Knee

An Advanced Cementless Option With All the Benefits of the Freedom Primary Knee System

The Freedom Porous Knee was designed to offer all the same benefits as the Freedom Primary Knee System in a cementless option for primary total knee replacement. This has become more important as the demand for knee arthroplasty increases among younger patients.

Freedom® Porous Knee System

Advanced Cementless Fixation. Designed for Modern TKA.
The Freedom Porous Knee System delivers a modern cementless solution engineered for reliable initial fixation, biologic ingrowth, and surgical efficiency. Built on advanced additive manufacturing and anatomic design principles, the system provides surgeons a seamless pathway to adopt cementless fixation within the proven Freedom® Knee platform

Cementless Tibial Foundation

Additively Manufactured Ti6Al4V Baseplate
The porous tibial baseplate is manufactured from Ti6Al4V using advanced 3D printing technology to create a fully interconnected porous lattice engineered to promote long-term biologic fixation

Anatomic, Asymmetric Geometry

Eight left and right–specific sizes are designed to maximize cortical coverage while minimizing overhang and soft tissue irritation

Bone-Preserving Broach-Only Keel

A punch-only keel preparation technique promotes immediate press-fit fixation while preserving subchondral bone. Multiple keel sizes allow surgeons to tailor fixation based on patient anatomy and bone quality.

Porous Femoral Component

The porous femoral component is fabricated from CoCrMo and offered in anatomic left and right configurations

Sintered Porous Coating Technology

The Freedom Porous Knee is a cementless, porous femoral option available in the Freedom Primary Knee System. The unique structure of the porous coating is developed through several layers of irregularly shaped CoCr beads for enhanced stability. The coating has greater average pore size and porosity to optimize bone-in growth, stability, and long-term fixation.
