Trochlear groove is angled 6° and has a constant radius of curvature, giving the surgeon the choice of keeping the native patella or replacing it. Trochlear groove is offset laterally by 2.3 mm to better reproduce the native femoral trochlea.
Cemented patellar implant available in inset and onset versions.

Single radius of curvature from 0° to 100° flexion that decreases beyond 100° to allow deep flexion.
6° anterior cut preserves the anterior cortex. 2° posterior cut improves primary stability due to nesting (associated with 6° anterior).

The centred cage is proportionately scaled, thereby preserving bone stock.
The posterior stabilisation cam provides stability by delaying contact (beyond 90° flexion) with the insert's post, while allowing some rotational movements.

Insert has curved anterior lip to ensure joint stability throughout the range of motion.
Planar posterior surface allows the lateral compartment to roll.
Posterior part of the insert is thicker to minimise wear in flexion.

Grooves on the lateral edges and around the tibial notch help guide insert placement. The insert clips into anterior edge of baseplate.

Tibial baseplate has an anatomical rear cut-out to help match bone morphology.
The contact area with the insert is highly polished, which reduces wear at the tibial baseplate–insert interface.
Keel and delta wing help to stabilise the baseplate in the tibia. The tibial keel is cylinder-shaped (Ø15 mm, length 35 mm) and the same for all sizes. The delta wing sizes match those of the baseplate.

6 posterior tabs, 2 clips and 1 anterior middle contact point help to fix the insert.

The ANATOMIC® instrumentation set can be used with Computer Assisted Surgery (AMPLIVISION®), without Computer Assisted Surgery or with patient-specific guides (i.M.A.G.E.®).
This knee replacement system can be implanted using:
- bone or ligament landmarks
- anterior or posterior reference points.
Either a 4-in-1 or 5-in-1 resection guide can be used. The 5-in-1 resection guide is available in Standard and I.M.A. versions.
