Update: Louisiana Man Alleges Severe Complications from Attune Knee

October 27, 2017 – A Louisiana man who claims he was severely injured after receiving the Attune Synthes implant during knee replacement surgery has filed a products liability lawsuit against the manufacturers. Plaintiff “Rocky” underwent total knee replacement surgery in January 2015 with the DePuy Synthes implant, after which he developed “severe pain, swelling, and instability in the knee and leg caused by loosening.” The device was subsequently found to be defective, and Rocky was forced to have knee revision surgery to remove the implant in July 2017, according to the lawsuit.

What is the DePuy Attune Knee?

The Attune Knee System was designed by DePuy Synthes to improve stability and range of motion in patients undergoing total knee replacement surgery. The implant features two new technologies:
The ATTUNE Rotating Platform Knee – Designed to improve conformity and stability throughout the range of motion and optimize kinematics.
Anatomic Patella – Designed to improve patella kinematics.

What’s the Problem?

Since it was approved by the U.S. Food & Drug Administration (FDA) in 2011, the Attune Knee System has been linked to numerous reports of tibial component loosening. This can cause the patient debilitating complications, many of which could require the need for painful revision surgery.

Attune Knee Complications

  • Severe pain
  • Inflammation
  • Infection
  • Bone damage
  • Muscle damage
  • Loss of / lack of bonding of the knee implant to the bone
  • Tibial loosening
  • Disassociation of the insert
  • Change in position of the components
  • Patello-Femoral Tracking-Lateral Release
  • Knee replacement failure
  • The need for revision surgery

Attune Knee Linked to Early Failure of Tibial Component: Study

A recent study published in the Journal of Knee Surgery found a high rate of debonding of tibial implant–cement interface with the DePuy Synthes Attune Knee System. The researchers looked at 3 hospital databases for patients who had revision surgery on a total knee arthroplasty (TKA) for tibial loosening at the cement-implant interface. They found 15 cases, 2 of which were demonstrated loosening of the tibial components, according to radiographic evaluation.

The study’s authors also found at least 21 reports of tibial loosening at the implant–cement interface in the Manufacturer and User Facility Device Experience database (MAUDE). They concluded that tibial component loosening is a rare complication of cemented TKA, which may be caused by increased constraint, reduced cement pockets, or reduced keel rotational stabilizers, according to the researchers.

Symptoms of Knee Replacement Failure

  • Persistent pain
  • Unusual Swelling
  • Stiffness across the entire knee (generalized) or in a small section (localized)
  • Instability and/or loosening of the implant
  • Warmth or heat in the knee

Why Our Law Firm Is Filing Individual Lawsuits Opposed To a Class Action

Although we are a nationally recognized class action firm, the Medical Device Litigation Group at our law firm has decided against the filing of a DePuy Synthes Attune Knee Class Action Suit, and is currently filing individual claims for people who suffered complications after receiving the implant. We are only filing individual claims because in this type of complex medical device litigation, class actions can force class members into lowball settlement agreements and higher attorney fees. We understand that our clients are suffering emotionally and economically due to loss of wages and/or high medical bills, and we plan to maximize each client’s recovery by filing individual DePuy Synthes Attune Knee lawsuits on their behalf.
