Attune Knee Replacement

Patients that underwent knee replacement surgery are now suffering from painful and debilitating complications. The Attune Knee System manufactured by DePuy Synthes, a subsidiary of Johnson & Johnson, has now been associated with reports of premature device failure. Patients with a failed Attune Knee System have reported needing additional surgeries to remove the failed device.

FDA Receives Hundreds of Adverse Event Reports

Patients suffering from mobility issues or with knee injuries may have knee replacement surgery to help increase their range of motion and use. The Attune Knee System is comprised of three parts that act together to imitate the natural movement of the knee. Unfortunately for many patients, the Attune Knee System resulted in premature device failure and other medical complications.

The U.S. Food And Drug Administration (FDA) has received hundreds of reports of complications via its Adverse Event Reporting System. Many reports include patients who needed additional revision and/or reconstructive surgeries after their knee implant procedures. Depuy Synthes itself has filed dozens of reports with the FDA that illustrate premature device failure.

Problems With The Attune Knee System

The component parts of the Attune Knee System are much smoother than those in other knee implants. Because it has smooth parts, medical glue does not properly hold the device on a patient’s tibia bone, which leads to a loosening that causes chronic pain, loss of mobility, and eventually total device failure. This effect was also observed buy nine prominent orthopedic surgeons who reported unusually high rates of premature device failure with the Attune System. In June 2017, these doctors published an article in the Journal of Knee Surgery to share their concerns.

Signs of a Defective Implant

Thousands of patients have already been implanted with the Attune Knee System. While most implants are designed to last fifteen years, patients with the Attune Knee System are reporting device failure within the first few years. Some complications that could indicate your Attune Knee System has failed include:

  • Instability in the leg when putting weight on the leg with the implant
  • Backwards or sideways movement of the knee
  • Unusual swelling
  • Chronic pain
  • Warmth or heat in the knee

Surgeries to replace the Attune Knee System carry serious risks to patients. Revision surgeries can cause muscle or nerve damage, bone loss, infections, and other serious complications. Some other patients have needed to undergo reconstructive surgeries after the implant damaged surrounding bones.

Failure to Warn

DePuy Synthes failed to warn patients of the premature device failure associated with the Attune Knee System. Patients were misled about the device’s efficacy, and they deserve to hold DePuy Synthes responsible.
