Description

Posterior-stabilised, fixed bearing, primary total knee replacement

Mediolateral implant coverage matches bone morphology
Stability and range of motion are ensured:
– in extension by congruent anterior rim
– in deep flexion by delayed contact between post/cam stabilization mechanism

Cemented and cementless versions: Plasma-sprayed Titanium (80 μm) and HAP (80 μm)

FEMORAL COMPONEN

Anatomic femoral component design based on a study of 420 knees digitized using the AMPLIVISION^® navigation
Lateralised trochlear groove better reproduces natural anatomy
Centred cage is proportionately scaled, thereby preserving bone stock
Posterior stabilisation cam ensures stability during flexion while allowing adequate rotational movements
Single radius of curvature from 0° to 100° flexion. Radius of curvature then decreases at posterior aspect of condyles to allow for high flexion
6° anterior cut preserves the cortex
Only 2.6 mm difference in anteroposterior height between sizes and in mediolateral (between 2 and 3.2 mm)
Material : Cobalt-chrome (CoCr)

INSERT

Insert has curved anterior lip to ensure joint stability throughout range of motion. Posterior stabilisation (PS) mechanism engages when knee is flexed more than 90°
Planar surface (large radius) posteriorly allows lateral compartment to roll
Polyethylene insert is thicker in posteroinferior part of post where it makes contact with PS cam
Material: Machined ultra-high molecular weight polyethylene (UHMWPE)

PATELLAS

nsert has curved anterior lip to ensure joint stability throughout range of motion. Posterior stabilisation (PS) mechanism engages when knee is flexed more than 90°
Planar surface (large radius) posteriorly allows lateral compartment to roll
Polyethylene insert is thicker in posteroinferior part of post where it makes contact with PS cam
Material: Machined ultra-high molecular weight polyethylene (UHMWPE)

KINEMATICS

Middle of PS cam is rounded to allow condyles to rotate around post
Contact between PS cam and post beyond 90° flexion and posterior displacement of femoral component allow for deep flexion while ensuring stability
Up to 10° recurvatum possible
PE insert is thickest posteriorly to support posterior aspect of condyles
Femoral component and insert can either be matched size-for-size or combined with implant one size above or below
