Maine Depuy Attune Knee Implant Lawyer
The DePuy Attune Knee System was touted as providing patients with increased stability and a better range of motion compared to older knee implants. However, many patients implanted with the device report spontaneous loosening or “debonding” of the tibial baseplate causing pain and instability and the need for revision surgery.
The Depuy Attune Knee System
The Attune Knee System is manufactured by DePuy Synthes, a subsidiary of Johnson & Johnson. The Attune Knee System was first cleared for marketing by the FDA in August 2010. The device was designed to give added range of motion and stability by employing Depuy’s Rotating Platform Knee technology. The Rotating Platform Knee has a special insert that helps a knee move more like it did before a replacement surgery by accommodating both bending and rotation.
Depuy Attune Knee System Failure & Injuries
Problems with Depuy Attune Knee System include loosening of the tibial component at the implant-cement interface. The tibial component is a flat metal part that attaches to the top of the resurfaced shin bone at the front of the leg. The tibial component is usually made of titanium alloy and is used with a polyethylene insert.
A recent study published in The Journal of Knee Surgery described the rate of tibial baseplate loosening with the Depuy Attune Knee System as “unusually high”. In some patients, the loosening has led to a failure of the device where the tibial component falls completely apart from the shin bone. The loosening often takes place within 1-2 years of a replacement surgery. However, in some cases, the debonding has occurred within only several months of implantation.
Symptoms and injuries associated with tibial baseplate loosening include:
- Knee pain and inflammation
- Knee instability
- Decreased range of motion
- Tissue damage
- Bone loss and fracture
- Revision surgery
Depuy Re-Designs the Attune Tibial Component
Recently, DePuy Synthes re-designed the tibial component of the Attune Knee System. DePuy admits that the re-design was necessary to “enhance fixation” by adding increased roughness and additional pockets for cement to adhere to the underside of the tibial baseplate. With its redesign, Depuy appears to acknowledge that the prior tibial baseplate design did not allow for sufficient bonding of the component to the shin bone thereby increasing its propensity for premature loosening.
Depuy Attune Knee Implant Litigation
In September 2017, the first wave of what will likely be many Attune Knee System lawsuits began to be filed against Depuy Synthes in courts around the U.S. Plaintiffs allege that the Attune Knee System is defectively designed because of the tibial baseplate’s propensity to loosen causing pain and the need for revision surgery. Plaintiffs further allege that Depuy Synthes has failed to adequately warn orthopedic surgeon and patients about the risk of tibial baseplate debonding.
