Weitz & Luxenberg is now accepting cases related to patients experiencing complications due to implantation with a DePuy Synthes Attune™ Knee System, a total knee replacement prosthesis produced by DePuy Synthes.

The DePuy Synthes Attune™ Knee System is indicated for use in individuals with a painful or disabled knee joint caused by osteoarthritis, post-traumatic arthritis, rheumatoid arthritis, or a failed implant.

The DePuy Synthes Attune™ Knee System has been at issue in reports of early implant failure due to loosening of the tibial component of the implant.

Failure of the DePuy Synthes Attune™ Knee System

Researchers have noted particular failure of the Attune™ Knee System between the tibial implant component and its cement bond. In an article published in The Journal of Knee Surgery, researchers found 15 cases of failure across three hospitals and noted 21 reports of failure occurring at the implant-cement interface in the U.S. Food and Drug Administration’ (FDA’s) Manufacturer and User Facility Device Experience (MAUDE) Database within a two-month period.

Interestingly, for the cases reported in the researchers’ hospitals, radiographs often failed to accurately identify loosening, and it was only during revision surgery that this complication was identified as the underlying cause of the implant’s failure, leading the authors to conjecture they “believe that this complication is underreported…”

Complications with the DePuy Synthes Attune™ Knee System

Reported complications in patients with the DePuy Synthes Attune™ Knee System include pain, swelling, or limited range of motion. Some patients may require or have already had revision surgery to correct loosening.

W&L Can Help Patients Harmed by the Attune™ Knee Replacement System

Weitz & Luxenberg’s Drug & Medical Device Litigation Unit Practice Group Co-Chair Ellen Relkin says the firm is interested in hearing from anyone who suffered complications or had or needs to have revision surgery because of the DePuy Synthes Attune™ Knee System. You may be entitled to compensation for medical expenses, lost wages, and other costs. An experienced attorney can help you explore your options.

Ms. Relkin has played lead roles in several major medical device litigations, including helping to secure a $2.5 billion settlement for patients harmed by defective DePuy ASR hip implants and a $1 billion resolution over recalled Stryker Rejuvenate and ABG II hip implants.
