Knee Replacement

Hip and Knee replacements are one of the most common operations in the United States and it is estimated that more than one million people in the U.S. receive these replacements each year. While these operations can change lives, they can also create a number of debilitating side effects. In many cases, the FDA has approved devices without carefully examining long-term results. Programs such as the 510(k) Premarket Notification process allow devices to be approved without detailed clinical testing results.

In March 2015, Zimmer Inc. issued a Class II recall for the Zimmer Persona Trabecular Metal Tibial Plate after receiving an unusually high number of complaints involving premature loosening of the implant and poor fixation. The company has reported approximately 6 complaints per 1,000 devices implanted, which is higher than the rate of complaints for similar implants.

About 36% of the complaints involved patients who had symptomatic problems, radiolucent lines, and/or needed revision surgery due to premature loosening of the implant.

The recall includes nearly 11,700 implants in all lots and sizes C-J. They were sold from November 2013 through January 2015 throughout the United States and in other countries.

The Zimmer Person knee implant may be prone to loosening, severe pain, and the need for early revision surgery.

Knee replacement lawsuits are being filed by thousands of patients who have been harmed by their knee replacement devices. Knee replacement lawsuits have been filed over devices such as Zimmer’s Natural Knee and NexGen systems, Smith & Nephew’s OXINIUM system, and Stryker’s Scorpio system.

If you or a loved one received a Knee Replacement and experienced:

  • Loosening of the implant
  • Radiolucent lines
  • The implant was replaced
  • Have been told by a doctor the implant needs to be replaced
  • Received a recall letter

You may be entitled to significant compensation from the manufacturer.

There are time deadlines to file a claim so don’t wait – act now.
