Manufactured by Johnson & Johnson subsidiary DePuy Orthopaedics, the Attune Knee System is one of the most popular knee replacement devices in use today. The U.S. Food and Drug Administration (FDA) approved the DePuy Attune Knee System in 2010, following the company's largest research and development project.
The knee replacement system was said to offer increased stability and a better range of motion, thanks to proprietary technologies that include:
- A gradually-reducing radius
- An S-curve design
- A locking base
- A rotating platform
- An anatomic patella
However, not all patients' experiences with the DePuy Attune Knee System have matched the marketing hype. In fact, numerous patients and their doctors have contacted the FDA to report serious side effects, complications, and other adverse events they've suffered as a result of these knee implants.
If you're considering the DePuy Attune Knee System, or are experiencing problems with your implant, here's what you need to know.
Side Effects and Complications Associated With the DePuy Attune Knee System
Knee replacement implants like the DePuy Attune Knee System are designed to improve mobility for those with worn, painful knee joints. In many patients, these replacement joints can last for up to 20 years.
However, some patients have reported premature failure of their implants as early as one or two years after the initial knee replacement surgery.
Signs and symptoms of failing DePuy Attune implants include:
- Joint stiffness
- Severe or throbbing pain
- Joint instability
- Warmth or heat in the knee joint
- Device loosening, dislocation, and dissociation
- Redness of the skin at the surgical site
- Grinding or clicking sounds when walking
- Immobility or decreased mobility
Some patients also report nerve, bone, or muscle damage related to their failing or failed Attune implants.
In many cases, after their joint replacement systems fail, patients are forced to undergo additional surgeries—such as revision or reconstructive surgeries—to repair or replace the failed implant, and correct any damage it's caused to the surrounding bone. These procedures are often far more painful, invasive, and lengthy than the initial knee replacement surgery, as they may require surgeons to break away components that have bonded to the bone improperly, or completely reconstruct parts of the bone destroyed by the implant.
For many patients, revision and reconstructive surgeries are also considered much riskier than their original knee replacement procedures. One reason is that first-time knee replacements are typically performed on members of an older patient population who, in the years between the joint replacement and device failure, have aged and may find themselves facing additional health challenges.
When these medically-fragile individuals are subjected to painful and invasive surgeries that require them to follow up with months of rehabilitation, the results can be devastating.
Issues With High Flexion Knee Systems
Many of DePuy's knee replacement products, including the Attune Knee System, utilize high-flexion technology. Designed to provide better flexibility and a greater range of motion, this high-flexion technology allows the implant to bend up to an impressive 155 degrees.
While this sounds fantastic for active patients who may be longing to regain their mobility, the results of the studies into the efficacy of high-flexion technology have been mixed. Additionally, high-flexion knee implants are thought to cause greater bone wear and joint instability in some patients.
Were You Harmed by the DePuy Attune Knee System?
A knee replacement surgery should improve a patient's life, not leave them in agonizing pain and trapped in a downward spiral of additional surgeries and rehabilitation treatments. If your DePuy Attune implants are failing and you're experiencing serious side effects and complications, you may be eligible for compensation for medical bills and other damages.
