VEGA System®

A pivotal breakthrough in knee replacement

VEGA System<sup>®</sup>

Based on a patent-pending post-cam design that optimizes pivotal motion while greatly reducing surface stress, the VEGA System represents a whole new way to think about PS knee replacement.

The VEGA System’s groundbreaking design concept works hand in hand with a unique 7-layer Advanced Surface (AS) coating, delivering exceptional kinematics and excellent wear results and jump distances.

  • Patent-pending Post-Cam Design – the unique design mimics natural knee kinematics and facilitates a large range of motion and optimized surface contact
  • Innovative 7-Layer AS Coating – Unparalleled surface hardness, substantially decreased wear rates and greatly improved scratch resistance.
  • Excellent Jump Distances – in conjunction with post height and inclination, the  post-cam design results in excellent jump distances, which increase flexion and can reduce sublaxation risks.
  • Intuitive IQ Instrumentation Platform – dual-purpose instruments, fewer trays and a simplistic design that allows quick, easy resizing and can reduce operating room time.
  • Better Bone Fit – 13 femoral sizes and 11 tibial sizes offer a wide-range of soft-tissue friendly implants.

Patent pending post-cam mechanism is designed to mimic natural knee kinematics by enabling a physiological pivot around the medial condyle. The design facilitates a large range of motion and optimized surface contact between the femoral and tibial components. The posterior inclination acts to avoid post-edge loading for better load distribution resulting in lower stress on the polyethylene.
