Three knees. One movement.
Compare the same knee and flexion angle.
Preparing the three models…
Native
ACL + PCL + menisci
ACL deficient
PCL + menisci retained
Resurfaced
Persona · PCL retained
● Medial ● Lateral · Fixed femoral reference-point paths projected over the tibia. These are not contact tracks or pressure maps.
Illustrative motion. Native and resurfaced paths are authored differently; this comparison does not establish clinical equivalence. Drag or zoom any model to move all three views together.
