EMPOWR 3D FEMOR AL COMPONENT T he propr iet ar y natural pivot ar t iculat ion of t he EMPOWR 3 D K nee™ replicates natural motion throughout a full range of motion, from early to deep f lexion, creating a more natural feeling knee.
POSTERIOR REFERENCING Pegs maintain same distance from posterior condyles for simple downsizing
5° ANTERIOR FL ANGE Prevents notching
9MM CONDYL AR THICKNESS Constant 9mm distal and posterior condyles across all sizes facilitate balancing flexion and extension gaps
WIDENED MEDIAL CONDYLE Encourages external rotation and aids in patellar tracking
DECRE ASED FEMOR AL R ADIUS Prevents overstuffing of flexion gap and permits up to 150˚ of flexion
SINGLE R ADIUS OF CURVATURE Allows for consistent soft tissue tension throughout flexion
DEEPENED TROCHLE AR GROOVE Deepened and lateralized trochlear groove provides optimal patella tracking and less tension on the quadriceps
EMPOWR PS FEMOR AL COMPONENT T he EMPOWR P S K nee™ recreates natural s t abilit y t hroughout a full range of mot ion, from early through deep f lexion, 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)
5° ANTERIOR FL ANGE Prevents notching
9MM CONDYL AR THICKNESS Constant 9mm distal and posterior condyles across all sizes facilitate balancing flexion and extension gaps
CONTOURED PS C AM Facilitates rotation in deep flexion and minimizes post wear
DECRE ASED FEMOR AL R ADIUS Prevents overstuffing of flexion gap and permits up to 150˚ of flexion
SINGLE R ADIUS OF CURVATURE Allows for consistent soft tissue tension throughout flexion
DEEPENED TROCHLE AR GROOVE Deepened and lateralized trochlear groove provides optimal patella tracking and less tension on the quadriceps
EMPOWR 3D TIBIAL INSERT Recreates natural mot ion wit h natural pivot ar t iculat ion. PCL RETAINING OR SUBSTITUTING Provides the option to preserve or sacrifice the PCL with equivalent clinical outcomes1
CONFORMING L ATER AL COMPARTMENT
LESS CONFORMING MEDIAL COMPARTMENT
Provides anterior-posterior stability and prevents paradoxical motion in early and mid flexion
Facilitates femoral rollback, resulting in tissue guided medial pivot motion in deep flexion
IMPAC TION FE ATURE Impactor tool securely snaps insert into place
ANTERIOR LOCKING TABS Securely locks insert into baseplate
TM
E+ POLYETHYLENE
PATELL A OPTIONS
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
Available in 26, 29, 32, 35 and 38mm options For use with EMPOWR 3D and PS femurs
EMPOWR PS TIBIAL INSERT Achieves natural stability through seamless cam ar ticulation.
MID FLE XION POST-C AM ENGAGEMENT Provides stability during mid flexion
1MM INSERT INCREMENTS Allows for optimal soft tissue balancing
IMPAC TION FE ATURE Impactor tool securely snaps insert into place
6MM SYMMETRIC ANTERIOR LIP Provides stability prior to post engagement, preventing anterior femoral translation
ANTERIOR LOCKING TABS Securely locks insert into baseplate
CONTOURED POST Facilitaties femoral rollback and external rotation, resulting in tissue guided medial pivot motion in deep flexion
EMP OW R T IBI AL B A SEPL AT E A symmetric ba seplate design ma ximizes covera ge and optimizes ba seplate f ixation.
POSTERIOR C APTURES Secures posterior portion of insert
DOVETAIL LOCKING MECHANISM Facilitates poly insertion and securely locks insert into place
ASYMMETRIC BASEPL ATE DESIGN Maximizes cortical coverage and prevents overhang
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)
WINGED KEEL DESIGN Provides rotational stability
