The Attune Knee System, which was designed by DePuy Synthes to improve stability and range of motion in knee replacement patients, has been linked to reports of pain and premature implant failure resulting in the need for revision surgery.

Update: Man Claims Attune Knee Left Him “Completely Disabled”
October 27, 2017 – A 66-year-old man from San Jose, CA., says he’s worse off after total knee replacement with the DePuy Synthes Attune Knee than when he was injured falling off a ladder. “Mike” has already undergone one knee revision surgery, and now doctors tell him he needs another one.
“My leg is so wobbly and my movements are so limited to the point that I’d rather have my leg amputated,” Mike said. “Now they tell me I need yet another entire knee replacement.”
What is the DePuy Attune Knee?
The Attune Knee System was designed by DePuy Synthes Joint Reconstruction (a subsidiary of Johnson & Johnson) to provide more stability and a greater range of motion compared to earlier total knee replacement systems. In order to accomplish this, the Attune Knee features a Rotating Platform Knee, which is designed to improve stability throughout the range of motion, and the Anatomic Patella, which is designed to improve patella kinematics.
What’s the Problem?
Complaints have recently surfaced from knee replacement patients who had problems after being implanted with the DePuy Synthes Attune Knee System. Some recipients of the implant reported premature failure within just a year or 2 of surgery, and sometimes in as little as a few months.
Knee Replacement Complications
- Severe pain
- Bone damage
- Muscle damage
- Loss of / lack of bonding of the knee implant to the bone
- Tibial loosening
- Disassociation of the insert
- Change in position of the components
- Patello-Femoral Tracking-Lateral Release
- Knee replacement failure
- The need for revision surgery
Attune Knee Linked to Early Failure of Tibial Component: Study
A recent study published in the Journal of Knee Surgery found a high rate of debonding of tibial implant–cement interface with the DePuy Synthes Attune Knee System. The researchers looked at 3 hospital databases for patients who had revision surgery on a total knee arthroplasty (TKA) for tibial loosening at the cement-implant interface. They found 15 cases, 2 of which were demonstrated loosening of the tibial components, according to radiographic evaluation.
The study’s authors also found at least 21 reports of tibial loosening at the implant–cement interface in the Manufacturer and User Facility Device Experience database (MAUDE). They concluded that tibial component loosening is a rare complication of cemented TKA, which may be caused by increased constraint, reduced cement pockets, or reduced keel rotational stabilizers, according to the researchers.
DePuy Knee Recalls
This is not the first time DePuy knee implants have caused serious problems. In 2013, DePuy recalled its LPS Diaphyseal Sleeve and the LPS Lower Extremity Dovetail Intercalary Component over concerns that the devices might not be able to handle the loads transferred to them during normal activities. As a result, FDA issued its most serious Class I Recall, which indicates a reasonable probability that use of the products “will cause serious adverse health consequences or death.”
