Pheno4U® TKA - Level 1

Navigated knee surgery taken to a new level

Times are changing, our thinking is changing, capabilities are changing - and so are our actions. Providing additional information on the individual anatomy, the Pheno4U® Level 1* software brings navigated TKA on the next level. Surgeon and patient benefit from a more individualized and data-driven workflow in the operating room - with additional safety options for a better load distribution across the implant.

Three different OrthoPilot Elite screens showing the different software types: mechanical alignment, kinematic alignment and restricted kinematic alignment.

Kinematic Alignment

Especially important in unrestricted kinematic alignment. The indicated load corridor helps to prevent overloading the implants beyond limits resulting in a potentially earlier revision.

/

Mechanical Alignment

Mechanical alignment for tibia resection with new design and load corridor.

/

Restricted Kinematic

Maximum medial and lateral contact stress to reduce implant wear and improve longevity of the implant is shown besides pure frontal and sagittal moments to avoid implant loosening.

Safety in frontal view

The load corridor indicates in this Kinematic Alignment planning, that frontal orientation of the femur in 2° Varus and the tibia in 5° Varus is out of the safe range (red).

/

Safety in sagittal view

The corridor indicates if the chosen angles of femur in relation to tibia are:

  • safe (green),
  • at the treshold area (yellow) or
  • beyond treshold area (red)

in regard to contact stress moments.

 

/

Safety in contact stress

Indication in red if maximum medial or lateral contact tension would be exceeded at only one point during walking gait cycle, respectively in yellow (limit) and green (safe zone).

/

An evaluation scale with three degrees is shown
The pressure of the implant is shown on the display
