On September 26, 2017, Pendley, Baudin & Coffin, L.L.P. filed the first pending federal lawsuit in Baton Rouge, Louisiana concerning a failure of a DePuy Attune knee implant.  The plaintiff is Rocky Thompson who underwent a subsequent surgery to remove and replace the defective Attune device.

The attorneys at Pendley, Baudin & Coffin, L.L.P. are actively investigating potential legal claims on behalf of those who were implanted with the DePuy Synthes Attune Knee System. The FDA has received numerous reports of early device failures. If you had surgery in 2011 or later and suffered complications or the symptoms above, please contact us immediately.

 Depicted above is the femoral component (left) and tibial component (right) of the Attune Knee System.  The femoral component (left) shows adequate cement and bone fixation.  The tibial component (right) shows little to no cement or bone adherent to the tibial component which is one of the causes of the alarmingly high rates of failure of the Attune implant.

DePuy Synthes Attune Knee Replacement Problems.

High numbers of complaints have recently emerged from patients who have been implanted with the DePuy Synthes Attune Knee System.  These reports, submitted to the FDA, indicate a high number of Attune failures caused by loosening or debonding at the cement interface of the tibial baseplate.  This mechanism of early failure generally occurs one to two years after the initial implant and often times earlier.   Loosening and debonding of the tibial baseplate or tray leads to pain, swelling, inflammation, infection, instability and other injuries including severe bone and/or muscle loss and damage.   After these symptoms appear, it often times leads to additional medical procedures or surgeries, referred to as a revision surgery.

When a knee replacement prematurely fails, patients can face infection, painful revision surgery, and extensive rehabilitation. Revision surgery is typically more difficult than the initial surgery, especially when bone loss has developed as a result of the implanted device. A common reason for knee implant failure noted by surgeons performing revision surgeries, appears to be when the device fails to adhere to the bone due to the lack of bonding between the bone and the implant.

How Do You Know If Your Attune Knee Implant Has Failed?

Symptoms of Attune Knee implant failure may include the following:

  1. Instability and Loosening: If you’re experiencing instability in your knee when you stand or put weight on it, or your knee is moving backwards or sideways in any manner, this may be a sign of a defective product. This condition grows increasingly worse as ligaments become inflamed and damaged.
  2. Unusual Swelling: When the knee lining becomes inflamed, it generally causes fluid to build up resulting in the sensation of swelling. This is another indication that something could be failing with a knee implant.
  3. Persistent Pain: If you’re experiencing constant or persistent throbbing or pain when your knee is in motion or while resting, you could be suffering from a failed implant.
  4. Warmth or Heat in the Knee: Although this is a normal sensation for a few months following surgery, if warmth or heat in your knee returns, this could be caused by a failed Attune knee implant.

Most common device failures listed in complaints to the FDA include:

  • Loss of or failure to bond
  • Component(s) worn
  • Fracture
  • Loss of Osseointegration
  • Metal shedding debris

“In all revision cases described in this study, there was an apparent loosening of the tibial component with gross implant motion between the tibial tray and tibial bone cement. All patients underwent revision of both tibial and femoral components.  In all tibial cases, the tibial component had debonded and was easily separated from the cement mantle.”   From Unusually High Rate of Early Failure of Tibial Component in ATTUNE Total Knee Arthoplasty System at Implant-Cement Interface.

 

Should I Investigate a Legal Claim?

If you or a loved one has suffered any of the problems listed above or implant failure following knee replacement surgery with an Attune Knee System, don’t wait for additional DePuy knee implant pain or a device recall before exploring your legal rights. Call us at (888) 725-2477 today.
