Why is there a DePuy Knee Replacement Lawsuit?

The DePuy Synthes Attune Knee System was first introduced in 2010 as a device that would improve a patient’s outcome for total arthroplasty to restore the function of the joints in the knee.

DePuy Synthes, a subsidiary of Johnson & Johnson, marketed the device as having “patented technologies” that significantly improve range and motion and provide patients “the confidence of a stable knee replacement.” However, dozens of reports have been filed with the U.S. Food and Drug Administration (FDA) detailing premature failures of the Attune© Knee System.

Thousands of patients have been implanted with the Attune© Knee System, many of whom have experienced premature failure that caused symptoms such as:

• Instability and loosening
• Swelling in the knee
• Infection
• Inflammation
• Bone or muscle damage
• Decreased range and motion
• Continuous pain

In many cases, the only effective remedy for patients who experience a defective Attune Knee System is to undergo revision surgery to remove the device and replace it.

Study Finds DePuy Knee Systems are Prone to Failure

In a 2017 study published in the Journal of Knee Surgery, nine orthopedic surgeons claim they had discovered a “high rate of debonding of tibial implant-cement interface” in the DePuy knee replacement system, which potentially caused significant instability in patients.

This means the surgeons discovered that the glue used in the Attune© Knee System does not adequately hold the device together or deteriorates prematurely. As a result, the tibial component of the Attune Knee© System loosens and destabilizes the entire knee replacement.

The surgeons examined the reports submitted to the FDA’s Manufacturer and User Facility Device Experience (MAUDE) database and found hundreds of reports that involved Attune. The authors of the study also reviewed three hospital databases and discovered 15 cases of patients who had experienced tibial loosening at the implant-cement surface and needed revision surgery.

Typically, the average knee implant is expected to have an average lifespan of 15 years, according to the American Academy of Orthopaedic Surgeons and the Agency for Healthcare Research and Quality.

However, the study found that patients experienced pain in weight bearing, effusion, and decreased range of motion (ROM) within two years after surgery. In the two months before the report was published, the authors found 21 reports of tibial loosening at the implant-cement interface in the MAUDE database.

DePuy Synthes Has a History of Knee Implant Recalls

The Attune© Knee System has yet to be recalled over the possibility of premature failures. However, a recent lawsuit filed against DePuy Synthes is not the first controversy the company has been involved in over its knee implant devices.

Between 2002 and 2013, DePuy Synthes recalled 277 knee implant devices and components. Four of the recalls were labeled Class I, which indicates there is a reasonable probability that using the product may cause severe adverse health consequences or death.

Additionally, in 2015 DePuy issued a Class II recall of the Attune© Knee Tibial Articulation Surface Instruments. Approximately 3,400 units were recalled after it was discovered that a small wire spring coil called the Balseal could break off and enter the surgical site and be left inside the patient without the surgeon’s knowledge.

DePuy offers no warranty on its defective knee replacement products, making revision surgery the only way to correct a defective knee implant.

How Do I Know if I Have a Case?

Approximately 600,000 people undergo surgery for knee replacements in the U.S. each year.

Unfortunately, patients are often misdiagnosed or not evaluated for loosened tibial components after a knee replacement surgery. Patients who report adverse health effects after receiving a DePuy Attune Knee System often experience the following symptoms:

• Instability in the knee when standing or placing weight on the affected area
• The knee moving in unnatural directions, such as backwards or sideways
• Fluid buildup leading to inflammation and swelling
• Constant throbbing pain
• Warmth or heat in the knee that begins several months after surgery
