In 2012, Zimmer introduced its Persona Personalized Knee Replacement System. When components in the system were called into question for loosening, Zimmer issued a recall of more than 11,500 porous coated, uncemented Zimmer Persona Trabecular Metal Tibial Plates, as well as the Zimmer Persona Tibial Articular Surface Provisional (TASP) Shim tool, in March 2015.

Zimmer Inc.'s voluntary recall is the latest in a number of publicized medical device recalls. For instance, Zimmer issued a voluntary recall of its metal-on-metal hip device (Durom Cup) in 2008, and another recall for its other knee implant (NexGen) in 2010. Recipients of the Durom Cup and NexGen devices have brought various claims against Zimmer, which resulted in pending Multidistrict Litigations (“MDLs”) in New Jersey and Illinois, respectively.

An MDL has not yet been established for the recalled Zimmer Persona TM Tibia claims.
