DePuy Attune Knee Problems

DePuy Synthes, a subsidiary of Johnson and Johnson, is the manufacturer of Attune Knee implants. These implants are used in patients who are in need of total knee replacement surgeries, also known as total knee arthroplasty. Some patients have reported complications such as loosening of the device and an increased need for early revision surgery.

Background

DePuy Orthopedics was founded in 1895, and was the first commercial orthopedics company in the United States. As of March 2017, a division of DePuy Orthopedics known as DePuy Synthes Joint Reconstruction is responsible for more than 200 products. An annual report conducted in 2016 by Johnson & Johnson found that their knee products generated sales of $1.5 million.

Investigation

The Attune knee went through a preliminary approval process known by the FDA as 510(k). This fast track process doesn’t necessitate clinical trials so long as a similar product exists on the market. The device was approved in December 2010 and was intended to accommodate flexion of the knee to 150 degrees. In 2015, FDA issued recall for an Attune Knee Tibial Articulation Surface instrument after discovering a small coil can become damaged and detached. There has been no further action by the FDA for all other DePuy Attune Knee implants.

A study by the National Institute of Health found that aseptic loosening is rare but increased risk with Attune implants. Cedars-Sinai defines aseptic loosening as “the failure of the bond between an implant and bone in the absence of infection.” Aseptic loosening is recognized by means of x-ray. There have been reports to the FDA of tibial loosening, pain, infection, disassociation of the insert, change in the position of the components and the implant sinking into the softer bone tissue, a complication known as tibial subsidence.
