Additional Manufacturer Narrative
After further review of additional information received the following sections g3, g6, h2, h3 and h6 have been updated accordingly.(h3) the revision reported was likely the result of mechanical overload on the posterior edge of the tibial insert; contributions from patient-related conditions, pcl tension issues, and the overall posterior slope of the tibial insert and tibial tray may have allowed for excessive posterior contact leading to wear of the polyethylene insert.However, the contributions of individual factors or a combination of the aforemention factors cannot be confirmed as the devices were not available for evaluation and additional information was not provided.The most probable root cause associated with the reported event of "prosthesis wear¿ is associated with material damage to a surface, usually involving progressive loss or displacement of material, due to relative motion between that surface and a contacting substance or substances.
