Apex K2 Hip Replacement Lawsuit

The Apex K2 hip replacement has been linked to a risk of metal corrosion. It was pulled off the market in Australia after a study found that nearly 10% of patients needed revision surgery within three years.

What is the Apex K2?

OMNI Life Sciences, a Massachusetts-based medical device company, gained approval for the Apex K2 hip replacement in 2004. It is a modular implant with a metal femoral stem and interchangeable metal components in the femoral neck and head.

Australia Pulls Apex K2 Off Market

The Apex K2 was withdrawn from the Australian market in October 2012, shortly after it was linked to a 9.3% risk of failure within three years, and a 5.5% risk within one year. Conclusions were based on data from a national joint replacement registry since 2006.

Metal Corrosion Risk

The Apex K2 is not a traditional metal-on-metal hip replacement. However, it was linked to a risk of metal corrosion in a study published by the Journal of Arthroplasty October 2015.

After looking at 95 patients with the Apex K2, researchers found 10 had evidence of fretting or corrosion from the anti-rotation pin. They also observed a wide variety of complications, including ALVAL and two patients who needed revision surgery due to deep joint infections.

Researchers noted the following complications:

  • Loosening
  • Subsidence (caving in or sinking)
  • Stem migration
  • Dislocation
  • Reactions to metal
  • Revision surgery
  • ALVAL
  • And more

What is ALVAL?

ALVAL is an acronym for “aseptic lymphocyte dominated vasculitis-associated lesions.” It can occur as a result of metal particles accumulating around a hip implant and causing inflammation. Patients with this complication may experience chronic pain, inflammation, soft-tissue growths (pseudotumors), and more.

What is the problem?

Hip implants are supposed to last at least 10-20 years, but an alarming number of metal-on-metal hips have been recalled because they can fail prematurely. Like most of these implants, the Apex K2 was approved by the FDA a 510(k) application. This type of approval lets manufacturers avoid rigorous safety studies so long as their device is “substantially equivalent” to another hip implant on the market.

The Schmidt Firm, PLLC is nationally recognized as a class action law firm, but our attorneys are not filing a class action lawsuit against Omni Life Sciences. Instead, we are filing individual lawsuits on behalf of people who were seriously injured or needed revision surgery after their Apex K2 hip implant failed prematurely.
