March 24, 2015 — Zimmer Inc. is recalling nearly 11,700 Persona knee replacements after receiving an increase in complaints about loosening and radiolucent lines, which are predictors of implant failure.
The implant has only been on the market for three years. It was promoted as a “personalized knee” with a better custom fit to match each patient’s unique biomechanics.
Unfortunately, patients may experience problems with initial fixation soon after receiving the implant. This could result in chronic pain, knee discomfort, loosening, and long-term knee problems. Revision surgery may also be necessary to remove and replace the device.
Zimmer reported receiving 6 complaints per 1,000 devices implanted, which was higher than the rate of complaints for similar devices. Overall, about 36% of complaints involved surgery due to premature loosening and/or symptomatic problems associated with radiolucent lines.
According to the Class II recall notification:
“Aseptic loosening of cementless tibial implant components is one of the most prevalent causes for revision in total knee arthroplasty and a number of factors may contribute to the loosening failure mode.”
The recall was issued for all sizes and lot numbers of the Persona Trabecular Metal Tibial Plate.
The implant has been on the market since November 2012 and was sold until the end of January 2015. Products were distributed all over the United States, including at least a dozen Veterans Affairs (VA) hospitals. It was also sold in Europe, Australia, and other countries.
