Abstract
A total ankle replacement system is presented. The total ankle joint replacement procedure can be used to treat persons with disability, deformity, or that are suffering from osteoarthritis and other arthritic conditions. The total ankle joint assembly generally comprises a tibial component, a talar component, and a bearing component, where the bearing component is positioned between and articulates with the tibial component and talar component to mimic the natural ankle joint movement.
