TRAX CR

Trochlear groove is angled 6°

The TRAX femoral component utilises an anatomical lateralised trochlear groove designed to replicate native anatomic patella motion throughout the range after TKR. [1] [2]

Cemented patellar implant available 

The TRAX knee system incorporates a single radius design during the main flexion arc from 0º to 90º offering patients a more natural motion. Deep flexion is incorporated by a reduced radii on the posterior condyles to ensure a maximum of flexion.

The TRAX system offers AXPe, highly cross-linked polyethylene mixed with vitamin E for all articulating surfaces: tibial insert and patella. AXPe uses high quality materials with verified and validated manufacturing processes.
 

The TRAX knee system’s asymmetric baseplate has been designed with surgeons to ensure uncompromising bone coverage whilst enabling surgeons to optimise tibial rotation. [3] [4]


 

The TRAX CR instrumentation is focused on efficiency with a limited number of trays.
 

It can be used with the amplivision system and the last generation of software that includes Personalized Approach based on bone morphing and ligament balancing.
