The Persona® TKA Tibial Placement App provides surgeons with an interactive experience that simulates placing an artificial knee implant onto a resected bone. Users are able to calculate and compare implant internal/external rotation, bone coverage and overhang. The user has multiple bone options to choose from, which include various sizes, genders and ethnicities. The Persona® TKA Tibial Placement App is unique because it allows surgeons to become familiar with the Persona tibial implants and virtually trial implants, all without the need of a physical product.
