DePuy Attune Knee Replacement Information

attune knee replacement lawsuit

Maglio Christopher & Toale is investigating defective knee replacement cases involving the DePuy Attune Knee Replacement System. People who’ve received this knee replacement reported premature device failure, some happening within months of surgery.

Many reports of early failure related to a lack of bonding and loosening of the tibial baseplate, which can lead to serious pain, bone loss, or muscle damage. The failure of a DePuy Attune knee replacement often requires painful and invasive revision surgery, and some of the damage caused by these defective knee implants may be irreversible.

Symptoms of a Failed Attune Knee Replacement

How do you know if your DePuy Attune knee implant has failed? Symptoms of a failed knee replacement 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 backward or sideways in any manner, this may be a sign of a failed knee implant.

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, 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.When a knee replacement prematurely fails, patients can face 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.

About the Attune Knee Replacement

The Attune Knee System, manufactured by Johnson & Johnson subsidiary DePuy Orthopaedics, is one of the most popular knee replacement devices on the market. Approved by the Food and Drug Administration (FDA) in 2010, the DePuy Attune Knee System was touted as being able to provide patients with increased stability and a better range of motion. However, some patients claim that the Attune knee replacement implants have not lived up to those expectations. In the years since its approval, the FDA has received numerous complaints from DePuy Attune patients who reported complications with their implant, including loosening of tibial components that necessitated painful and invasive revision or reconstructive surgeries.

Most common symptoms reported to the FDA include:

  • Tibial loosening
  • Pain
  • Disassociation of the insert
  • Change in the position of the components
  • Patello-femoral tracking-lateral release

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


DePuy’s History of Orthopedic Problems

The Attune Knee Replacement System is manufactured by DePuy Synthes – a subsidiary of Johnson & Johnson. This isn’t the first time the company has encountered problems with its knee replacement devices. DePuy is primarily known for its total hip and knee replacement systems. Although the company is a leader in the medical device manufacturing field, it’s had many legal battles due to defective or failed implants.attune knee replacement diagram

  • DePuy recalled components of its Limb Preservation System knee implant in 2013 after they were linked to reports of loosening, fracturing, and premature failure.
  • DePuy also recalled its ASR metal-on-metal hip devices in 2010 due to unusually high failure rates and is currently facing nearly 9,000 lawsuits from patients who claim to have experienced severe health problems related to its Pinnacle hip implant.
  • Between 2002 and 2013, DePuy recalled 277 knee implant devices, instruments, and components. Four of these recalls were labeled as Class I – a recall that indicates there is a reasonable probability that using the product will cause serious adverse health consequences or death.
  • In 2015, DePuy initiated a Class II recall of the Attune Articulation Surface component after finding that a spring coil could break off and enter the surgical site without the surgeon’s knowledge.
