Prescribing Information for the DePuy Attune® Knee System

For people living with painful knee joints and reduced mobility caused by arthritis, injury, or excessive wear and tear, completing even the most mundane tasks can be a challenge.

In 2010, when the U.S. Food and Drug Administration (FDA) approved the DePuy Knee System—a total knee replacement solution that touted its ability to offer improved stability and a greater range of motion— many patients figuratively jumped at the chance to be able to literally jump (or walk, jog, or cycle) again. As a result, tens of thousands of people around the world are living with DePuy Attune Knee System implants.

While these implants have helped many patients regain mobility, they haven't worked for everyone. A number of serious Attune Knee side effects and complications have been reported to the FDA but, so far, DePuy has not made revisions to, or revised, the product.

If your doctor has recommended the DePuy Attune Knee System, here's what you should know.

About the DePuy Attune Knee System

info_about_knee_replacement

Manufactured by DePuy Orthopaedics, a subsidiary of Johnson & Johnson, the Attune Knee System was developed as part of the largest research and development project in the company's history. 

The comprehensive, integrated knee replacement system features a state-of-the-art design intended to improve the patient's range of motion while offering improved stability.

The DePuy Attune Knee System features proprietary technology such as:
  • The Attune Gradius Curve, which gradually reduces radius, increases range of motion and delivers stability.
  • The Glide-Rite Articulation, which ensures the kneecap has a gliding, fluid motion.
  • The Softcam Contact S-curve design that reduces the stress on the implant while offering improved stability and flexibility.
  • The Logiclock Tibial Base that locks in place to reduce excessive wear.

The Attune Knee System also features high-flexion technology that makes it possible for the implant to flex 150 degrees.

Indications and Contraindications

DePuy's Attune Knee System was designed for patients suffering from extremely painful or disabled knee joints caused by post-traumatic arthritis, osteoarthritis, or rheumatoid arthritis. Due to the implant's ability to bend 150 degrees—similar to the movement the knee makes when someone crosses their legs, squats or kneels—it's considered particularly suitable for younger patients who enjoy an active lifestyle that would be difficult to maintain with a traditional knee replacement implant.

Not all patients are suitable candidates for this system. According to DePuy, the Attune Knee implants are contraindicated for patients who have an active local or systemic infection, or whose bone quality is inadequate to support the implant.

Side Effects and Complications Associated With the DePuy Attune Knee System

After healing from their total knee replacement surgery, most patients expect to have less pain and more mobility. However, some DePuy Attune Knee System patients develop infections or continue to experience stiff, painful and swollen joints.

Some patients and doctors claim these implants have an unusually high rate of premature failure. Whereas most knee replacement systems are designed to last up to 20 years, some Attune Knee patients report their devices failed within one or two years of implantation.

Additionally, a recent study published in the Journal of Knee Surgery found that the DePuy Attune Knee System's tibial implant component had a high rate of de-bonding from the device's cement interface.

When a system like this fails prematurely, doctors may recommend a revision or reconstructive surgery. Unfortunately, these procedures are more painful and invasive that the original knee replacement, and requires a longer recovery period.
