The DePuy Synthes Attune Knee Implant System was designed to improve stability and range of motion in patients undergoing total knee replacement surgery. However, the device has been linked to numerous reports of tibial component loosening leading to debilitating complications.
A recent study published in the June 2017 Journal of Knee Surgery found an unusually high rate of de-bonding of tibial implant-cement interface with the DePuy Synthes Attune Knee Implant system, which has been causing it to fail prematurely.
In the study, researchers looked at patients who had revision surgery on a total knee arthroplasty (TKA) for tibial loosening at the cement-implant interface. In looking at three hospital databases for such patients, they found 15 cases. Surgeons removed the implant from these patients within two years of their initial surgery and all had loose components in the knee with no bone cement bonding the tibial baseplate to the bone.
The study also found 21 reports of tibial loosening at the implant-cement interface in the Manufacturer and User Facility Device Experience database (MAUDE).
According to the study, “several possible reasons include increased constraint, reduced cement pockets, and reduced keel rotational stabilizers. The tibial component, which has greater torsional loads, has lower surface roughness than femoral component.”
Unfortunately, some patients suffer loose components within months of having the initial knee replacement using the DePuy Attune implant. Other patients may not experience loose components for years. How long it takes for this to happen depends on whether the implant was cemented to the bone or whether it gradually loosened over time.

Unfortunately, when these devices fail because of component loosening, a revision surgery may be needed. Revision surgeries are typically more difficult than the initial knee replacement surgery, especially if bone loss has developed as a result of the device.
When a knee replacement prematurely fails, you can face many serious issues ranging from infections to muscle or nerve damage, bone loss and more. Revision surgeries are expensive and can result in many ongoing expenses.
