Depuy Knee Replacement

DePuy Knee Replacement

The DePuy Knee replacement was introduced as the DePuy Attune Knee System in 2010 and approved by the FDA for revision knee replacement surgery. It is Engineered as a device that can properly restore the function of joints in the knee. While being marketed as one of the most advanced knee replacement systems on the market. Since then the FDA has received hundreds of complaints about the DePuy Attune Knee Replacement. Thousands of patients who have received these knee replacements have encountered premature failure of the device. This failure can cause the following symptoms:

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

In plenty of cases, the only way to relieve patients who experience these symptoms is to undergo revision surgery. Revision surgery is the painful process of replacing the defective DePuy Knee Replacement with a new one.   

Reports of Knee Replacement Loosen and Fail

Shortly after the DePuy Attune Knee Replacement was approved by the FDA, they began receiving complaints. All of these many complaints culminated in a 2017 study published in the Journal of Knee Surgery. In this study, 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.

Simply, this means that the orthopedic surgeons discovered that the glue is being used to bind the Attune Knee System is faulty. The glue may not adequately hold the device together or it deteriorated prematurely. As a result of the faulty glue, the Attune Knee System may loosen and destabilize the knee replacement from the tibia.

Reports submitted to the FDA’s Manufacturer and User Facility Device Experience (MAUDE) database were reviewed by surgeons to reveal that 232 of the reports involve the DePuy attune knee replacement. In addition to the MAUDE report, authors of the 2017 study discovered that three separate hospital databases reported 15 cases of patients with tibial loosening leading to revision surgery.

According to the American Academy of Orthopaedic Surgeons and the Agency for Healthcare Research and Quality, the average lifespan of knee replacements is 15 years. Unfortunately, the 2017 study found that patients were experiencing complications from knee replacements within two years.
