The HINTEGRA Total Ankle Replacement (TAR) is an unconstrained, three-component system that provides inversion-eversion stability and was designed in 2000 by Beat Hintermann, Greta Dereymaeker, Ramon Viladot, and Patrice Diebold. The mobile bearing provides axial rotation and normal flexion-extension mobility.1-3 The HINTEGRA TAR includes two metallic components and an ultrahigh-density polyethylene mobile bearing. The non-articulating surfaces have a porous coating with 20% porosity and are covered by titanium fluid and hydroxyapatite.
