FIRST knee system

Total knee prosthesis

The FIRST knee system is designed to provide greater stability and range of motion in deep flexion.

Balance between stability and movement

Stable from extension to flexion

Single radius of the femoral component from 0° to 90° of flexion inducing an ultra-congruent femur-insert allowing for high antero-posterior stability during the transition from extension to flexion.

Designed to promote deep flexion performance

From 90° of flexion, the posterior stabilization mechanism is activated with the cam coming into contact with the tibial stop.
The change in radius at the posterior condyles and the posterior design of the tibial insert promote rollback movement and the performance of the tibia. in deep flexion.

A multitude of options, one system

Full range

Choice between a fixed and a mobile tibial plateau while preserving a close kinematic relationship between the two.
Choice of cemented and cementless fixation for all femoral and tibial components
Option of modularity with femoral and tibial extension pins

Move easily to greater load

Increased intraoperative load possible with FIRST REV due to the identical cut concept with an additional cut for the intercondylar cage

Allergic risks controlled

Additional coating of titanium niobium nitride (TiNbN) with FIRST Sensitive for a reduction of the amount of Cr, Co and Ni ions released as well as a reduction of PE wear.
