Persona: The Personalized Knee System was first introduced to the market by manufacturer Zimmer, Inc. in 2012 as a cementless knee replacement system.

Quickly thereafter adverse events such as radiolucent lines, or large gaps between the implant and bone, and implant loosening led to a voluntary recall of the product on March 12, 2015 by Zimmer, Inc.

Nearly 12,000 Personas have been distributed worldwide, and it is expected that several thousand lawsuits will be filed across the country.
