Product Overview
-The Evolution® medial-pivot knee system addresses
the limitations of traditional designs and today’s
patient needs by delivering superior flexion stability,
anatomic motion, and wear-limiting design
characteristics through three primary knee options.1-
7 The three options offered are: Cruciate-Substituting
(CS), Cruciate-Retaining (CR), and Posterior Stabilized
(PS). All three incorporate the medial-pivot concept
through spherical femoral condyles while matching
the highly conforming medial “socket” and the 15°
lateral arcuate path.
Design features:
Flexion stability
-Promoted through high medial conformity and
constant radius spherical condyles.
-Increased flexion and enhanced quadriceps efficiency
achieved through longer constant flexion radius with
more posterior, medial dwell point.
Anatomic motion
-Driven through a stable medial compartment and a
mobile lateral compartment that rotates or pivots
about the medial.
Wear-limiting design1-7
-Enabled through a maximized contact area and
repeatable motion path that minimizes contact
stresses.
The difference is in the design
-Why set out to design a better knee system? Today,
according to the latest literature, nearly 20% of all
patients are unhappy with their total knee
replacement due to residual pain, functional issues
and early implant failure.8
