Evolution® CCK Knee System

For many years, orthopedists have clung to the concept of a J-curve, multi-radius knee that rolls back in flexion. Recent kinematic and radiographic studies support medial-pivoting kinematics and their impact on stability of the knee. These studies demonstrate that the normal knee exhibits a fixed flexion-extension axis with a stable medial compartment and a mobile lateral compartment.1
