DePuy ATTUNE© Knee Replacement Lawsuit Update

Knee Replacement Implant

Thousands of people have filed knee replacement lawsuits in recent years claiming device manufacturers are selling faulty implants. A growing number of patients with DePuy Attune knee replacement devices report loosening problems with the device. As such, lawsuits are being filed over the side effects when the device fails.

Attune Knee Replacement Lawsuit Updates

May 31, 2018. A case on behalf of Donald Sizemore was filed, Sizemore underwent a total knee replacement in which he received an Attune Knee device. He began “experiencing severe pain and discomfort caused by, among other things, loosening of an allegedly defective tibial baseplate component.” Two months after the knee replacement, he underwent revision surgery to remove and replace the DePuy Attune knee device.

Sizemore’s complaint indicated that DePuy Synthes and its parent company, Johnson & Johnson, manufactured and sold defective components, which made the knee replacement system prone to failure.

DePuy Attune Knee System

The Attune Knee System is a total knee replacement device manufactured by DePuy Orthopedics (a subsidiary of Johnson & Johnson). According to the manufacturer’s website, the Attune device is a “new state-of-the-art knee replacement system, designed to work in harmony with your knee muscles and ligaments.”

The DePuy Attune Knee System was approved by the US Food and drug Administration in 2010. Unfortunately, there have been several reports of early failure of the system that include lack of bonding of the knee replacement device and frequent reports of loosening of the tibial baseplate. These complications can lead to other adverse conditions such as muscle damage, pain and bone loss.
