Zimmer Inc. released the Persona Knee implant for Total Knee Arthroplasty (TKA) in March 2012. They marketed the product stating, “Zimmer is redefining knee arthroplasty and ushering in a new era of personalization with the introduction of the Persona Knee.”
On March 12, 2015, Zimmer Inc. recalled the Persona Knee after less than three years on the market. The recall includes approximately 12,000 implants sold throughout the United States. The recall was initiated because the knees are prone to loosening, resulting in severe pain for the patient and a subsequent need for revision surgery.
Zimmer Recalls Persona Knee ImplantZimmer Inc. issued a voluntary Class 2 recall of the Persona Trabecular Metal Tibial Plate. Recall notices were sent to affected distributors, hospitals, and surgeons in February.
According to the Food and Drug Administration (FDA), the manufacturer received “An increase in complaints of loosening and radiolucent lines.” Radiolucent lines are defined as radiolucent intervals (measured in millimetres) between the cement and the bone. They are transparent to X-Rays. Radiolucent lines are symptomatic of a poorly-fixated knee implant, malalignment, and premature or aseptic loosening. Progressive radiolucent lines are commonly associated with early failure of the acetabular component of the knee implant. Component loosening and polyethylene wear may be attributed to the cementing technique and/or implant design.
The Australian Government released a hazard alert stating, “Out of the 0.61% complaints received, 36% identified symptomatic radiolucent lines or were revised for loosening, and 28% identified asymptomatic radiolucencies.”
Your Options & Filing a Zimmer Persona Knee LawsuitZimmer advertised on their website, “The Persona System makes the most clinically successful knee replacement more personalized than ever by focusing on the unique needs of the patient, surgeon and institution.” Unfortunately, individuals implanted with this defective device experience serious problems and may require revision surgery.
We recommend following up with your orthopedic surgeon regarding this matter. Consider requesting that your orthopedic surgeon order an X-Ray or other radiological study in order to evaluate the current status of your Zimmer Persona knee. We believe it is in your best interest to have your knee evaluated due to the fact the implant can lead to loosening failure mode and contribute to the need for revision of the total knee arthroplasty.
