FEATURES BROCHURE
EMPOWR D Knee™ EMPOWR PS Knee™
The conforming insert of the EMPOWR D Knee enables its use with or without a PCL.
The EMPOWR PS Knee replaces PCL function through a cam and post design.
EMPOWR D KNEE™ EMPOWR PS KNEE™
Single Radius Femoral Designs
Conforming Insert Designs
Asymetric Tibial Baseplate Design
MM CONDYLAR THICKNESS
Constant 9mm distal and posterior
condyles across all sizes facilitate
balancing flexion and extension gaps
SINGLE RADIUS OF CURVATURE
Allows for consistent soft tissue tension
throughout flexion
POSTERIOR REFERENCING
Pegs maintain same distance from posterior
condyles for simple downsizing
WIDENED MEDIAL CONDYLE
Encourages external rotation and
aids in patellar tracking
DECREASED
FEMORAL RADIUS
Prevents overstung of
flexion gap and permits up
to 150˚ of flexion
° ANTERIOR FLANGE
Prevents notching
DEEPENED TROCHLEAR
GROOVE
Deepened and lateralized
trochlear groove provides
optimal patella tracking and
less tension on the quadriceps
EMPOWR D FEMORAL COMPONENT
The proprietary natural pivot articulation of the EMPOWR D K n e e™
replicates natural motion throughout a full range of motion, from early
to deep flexion, creating a more natural feeling knee.
BONE SPARING BOX WIDTHS
Preserves bone in smaller joints and are
available two widths:
Sizes 2-5 (18.5mm)
Sizes 6-11 (22.5mm)
CONTOURED PS CAM
Facilitates rotation in deep flexion and
minimizes post wear
° ANTERIOR FLANGE
Prevents notching
MM CONDYLAR THICKNESS
Constant 9mm distal and posterior
condyles across all sizes facilitate
balancing flexion and extension gaps
EMPOWR PS FEMORAL COMPONENT
The EMPOWR PS Knee™ recreates natural stability throughout a full range of motion,
from early through deep flexion, creating a more natural feeling knee.
SINGLE RADIUS OF CURVATURE
Allows for consistent soft tissue tension
throughout flexion
DECREASED
FEMORAL RADIUS
Prevents overstung of
flexion gap and permits up
to 150˚ of flexion
DEEPENED TROCHLEAR
GROOVE
Deepened and lateralized
trochlear groove provides
optimal patella tracking and
less tension on the quadriceps
EMPOWR D TIBIAL INSERT
Recreates natural motion with natural pivot articulation.
E+ POLYETHYLENE
The knee-specific formula of the tibial inserts
and patella components are blended with
vitamin E and moderately cross-linked to
reduce oxidation and reduce long-term wear.2
TM
PCL RETAINING OR SUBSTITUTING
Provides the option to preserve or sacrifice the
PCL with equivalent clinical outcomes
CONFORMING LATERAL
COMPARTMENT
Provides anterior-posterior
stability and prevents paradoxical
motion in early and mid flexion
LESS CONFORMING MEDIAL
COMPARTMENT
Facilitates femoral rollback,
resulting in tissue guided medial
pivot motion in deep flexion
ANTERIOR LOCKING TABS
Securely locks insert into baseplate
MM ANTERIOR LIP
Prevents anterior femoral
translation
IMPACTION FEATURE
Impactor tool securely snaps
insert into place
PATELLA OPTIONS
Available in 26, 29, 32, 35
and 38mm options
For use with EMPOWR D
and PS femurs
EMPOWR PS TIBIAL INSERT
Achieves natural stability through seamless cam articulation.
MM JUMP HEIGHT
Prevents anterior
femoral dislocation
MID FLEXION POSTCAM ENGAGEMENT
Provides stability during mid flexion
ANTERIOR LOCKING TABS
Securely locks insert into baseplate
6MM SYMMETRIC ANTERIOR LIP
Provides stability prior to post engagement,
preventing anterior femoral translation
IMPACTION FEATURE
Impactor tool securely snaps
insert into place
MM INSERT INCREMENTS
Allows for optimal
soft tissue balancing
CONTOURED POST
Facilitaties femoral rollback and external
rotation, resulting in tissue guided medial
pivot motion in deep flexion
WINGED KEEL DESIGN
Provides rotational stability
ASYMMETRIC BASEPLATE DESIGN
Maximizes cortical coverage and
prevents overhang
EMPOWR TIBIAL BASEPLATE
Asymmetric baseplate design maximizes coverage and optimizes baseplate fixation.
POSTERIOR CAPTURES
Secures posterior portion of insert
DOVETAIL LOCKING MECHANISM
Facilitates poly insertion and securely
locks insert into place
TIERED KEEL SIZES
Preserve bone in smaller joints and
are available in three lengths:
Small: Sizes 2-3 (31mm)
Medium: Sizes 4-8 (35mm)
Large: Sizes 9-11 (43mm)
