Abstract
The purpose of this study was to evaluate the wear and surface damage mechanisms of polyethylene in retrieved CHARITE total disc replacements. The retrieved implants showed evidence of adhesive/abrasive wear mechanisms in the central domed region of the implants. In addition, there was also evidence of macroscopic rim damage, including radial cracking, plastic deformation, and third body damage. The retrieved total disc replacements (TDRs) displayed surface damage observed previously in both hip and knee replacements. The information from this study will be useful for engineers seeking to adequately replicate long-term, clinically relevant damage modes of TDRs using in vitro testing methods.
