Oblique (a) and anteroposterior (b) view with landmark features of the uncemented Attune mobile bearing (“rotating platform”) implant (DePuy Synthes, Warsaw, Indiana, USA). A gradually reducing radius of the femoral component (1) allows for more stability during flexion. The patellofemoral surface of the femoral component mimic the original anatomy more closely (2), providing more natural kinematics and patellar tracking during knee flexion. A porous coating on the 4 pegs and proximal part of the central cone provides an ideal environment for fixation (3). Images provided courtesy of DePuy Synthes
