Commonly asked questions about ATTUNE Knee System:

What Is the ATTUNE Knee System?

The ATTUNE Knee System is a device used in knee replacement surgeries that is manufactured by DePuy Synthes, a subsidiary of Johnson & Johnson. The device is advertised as being able to give patients increased stability and range of motion following knee replacement procedures.

The ATTUNE System includes a “GRADIUS Curve,” designed to improve stability during everyday activities like walking or going down stairs. The “GLIDERIGHT Articulation” aims to provide smooth motion as your knee cap interacts with the rest of the knee. The “AOX Polyethylene” is a plastic material that is designed to replace cartilage in the knee, which can help improve the device’s strength and resistance to wear.

Recently, however, there have been numerous reports of the device’s early failure. One study published in the Journal of Knee Surgery calls the rate of early failure “unusually high.” Most of these failures have been found to be the result of tibial loosening at the implant-cement interface.

What Are Complications Of DePuy’s ATTUNE Knee System?

According to the FDA, serious complications may be associated with any total knee joint replacement procedure. These complications include, but are not limited to:

  • Loosening of the prosthetic knee components
  • Dislocation and/or joint instability
  • Malalignment of the prosthetic knee components
  • Bone fracture
  • Nerve damage
  • Infection
  • Excessive wear secondary to damage of mating wear surfaces and/or debris that can initiate osteolysis which may result in loosening of the implant

In the case of the ATTUNE System, patients have been experiencing pain on weight bearing, effusion and decreased range of motion within two years of knee replacement surgery. Many of these complications are the result of tibial components loosening.

Why was the ATTUNE Knee System Recalled?

DePuy recalled the ATTUNE Knee System in 2015. The reason for the recall was the potential for the Balseal, a small wire spring located on the post feature of the ATTUNE Knee Tibial Articulation Surface Instruments used in training, to become damaged and disassociate.

If the Balseal is separated from the post, it has the potential to enter the surgical site and be left in the patient if the surgeon is unaware of the disassociation.

What are the Criteria for Filing an ATTUNE Knee System Lawsuit?

Despite the overall high success rate in knee replacement surgeries, researchers have identified larger-than-usual failure rates with the DePuy Synthes ATTUNE® Knee System.

Problems with ATTUNE include loosening of the tibial component at the implant-cement interface within the first two years after implant. Patients often present with pain on weight bearing, swelling, and decreased range of motion.

Researchers believe that these failures are likely underreported, as competing companies cannot provide data on the revision components that they replace.

We are currently investigating cases involving individuals who have undergone revision surgery due to loosening after a knee replacement using an ATTUNE device. The following criteria must be met to pursue a lawsuit:

  • Implant of DePuy ATTUNE Knee after February 13, 2015
  • Underwent revision surgery to replace the implant
