DePuy Attune Knee Implant Failures. Johnson & Johnson and its DePuy Orthopaedics subsidiary, the world’s second-largest manufacturer of artificial knee implants are exposed to personal injury and product liability lawsuits over claims involving design problems with the Attune knee replacement device.
The lawsuit allegations note that many patients had to undergo painful extensive revision surgery to remove and replace defective DePuy Attune knee devices.
DePuy Attune Knee Implant Failures
A case in point, according to Robert Long from Kentucky, his Attune knee replacement device was defective and caused loosening of the tibial baseplate and the need for painful revision surgery. Long, filed his knee injury complaint in the U.S. District Court for the Eastern District of Kentucky.
Long claims that all of his injuries and complications were caused by the defective design, lack of adequate warnings, and unreasonably dangerous character of the Attune system.
Long further alleges that the manufacturers knew, or should have known, that there were problems with the design of the knee replacement system, yet continued to market and sell the knee components anyway, putting him and others at risk with the use of the Attune system.
Long had a right total knee replacement surgery in early 2015, with the DePuy Attune knee implants. The Attune knee replacement device is composed of a fixed tibial insert and fixed tibial baseplate. Shortly after the knee replacement surgery, Long began to experience severe knee pain, knee instability and trouble walking.
His doctors found aseptic loosening of the tibial baseplate, and Long had knee revision surgery two years later to have the device replaced.
Similarly, Joyce Rogers filed her product liability claim late last year against DePuy Orthopaedics and Johnson & Johnson blaming the DePuy Attune knee replacement system as defective and prone to failure. According to Rogers, from Mississippi, she had to undergo painful and risky revision surgery less than two years after receiving the knee implant.
Rogers filed in the U.S. District Court for the Southern District of Mississippi, alleging that Johnson & Johnson allowed a dangerous device to be implanted in her body and in thousands of other patients.
What is the DePuy Synthes Attune Knee system?

What is the problem with the DePuy Synthes Attune Knee system?
According to some experts, there are serious post-marketing adverse event reports with the DePuy Synthes Attune Knee system. As of June 2017, the FDA has already about 1,400 reports involving failure with DePuy Attune knee replacements, including at least 633 cases where individuals have already required revision surgery.
Medical studies found early failures in the DePuy Attune knee replacements
According to a study published in the June 2016 issue of the Journal of Arthroplasty, knee implants like the Attune may have a high rate of baseplate loosening and failures due to its thicker cobalt-chromium tibial trays increasing the risk of bone loss.
In the Journal of Knee Surgery, researchers found an increase in DePuy Attune knee loosening and failures related to the implant-cement interface.
DePuy Attune knee replacement lawsuits
DePuy Attune knee lawsuits claim that the key reason for the early knee implant failure is mechanical loosening, which is caused by the failure of the bond between the tibial baseplate and the implant-cement surface. The lawsuits claim that when the loosening happens, the knee implant device can disconnect from the existing bone, resulting in implant failure.
Injuries include DePuy knee replacement tibial baseplate loosening which leads to pain, infection, inflammation, and bone or muscle damage.
