SmartKnee Classic™ Primary Knee Prosthesis
 |
The SmartKnee Classic™ is
just one of the extensive range of knee implants offered
by Orthopaedic Innovation
The Classic™ offers
a clinically proven design that has been
developed as a result of extensive research to be as
anatomically accurate as possible, matching the shape
and size of the distal end of the femur, proximal end of
the tibia and the patella.
Accurately determining the
ratio between the inside and outside diameters of the
knee, as well as the ratio between the anteroposterior
diameter, means that the covered area of the bone is
increased and the possibility of uneven distribution of
local stress on the cutting surface is avoided.
Preventing uneven distribution of local stress also
ensures that the prosthesis does not sink.

Key Features
• Significantly reduced wear
The curve-on-curve design of the tibial-femoral articulating
surfaces produces even distribution of stress and reduces the
wear of the insert
• Inlaid design for maximum contact
The patella component is an inlaid design which, when compared
with an overlaid design, increases the contacted area between
the patella prosthesis and patella, so avoiding any possible
loosening of the patella component.
• Reduced contact stress
The curvature surface of the PS insert stake is specifically
designed so that it decreases the contact stress during the
flexion movement of the knee joint, subsequently decreasing the
wear of the UHMW-PE of the insert.
• Robust locking mechanism
The reliable design of the locking mechanism between the insert
and the tibial component prevents the micro motion which can
wear the bottom surface of the insert.
• Maximum flexibility
The knee offers a maximum flexion of 134.5° which is more than
adequate to meet the requirements of the majority of patients in
their daily life.
