Millions of Americans are living with artificial knee implants. In fact, according to the Centers for Disease Control and Prevention (CDC), more than five million Americans over age 45 had their knees replaced in the 10-year period from 2000 to 2010, making it one of the most common inpatient surgeries performed that decade.
While most patients who undergo knee replacement surgeries hope their artificial knee implants will restore the stability and range of motion lost to injury, excessive wear, or arthritis, that isn't always the case. Studies show that between 10 and 20 percent of knee replacement patients aren't completely satisfied with the outcome of their knee replacement procedure.
One company, Johnson & Johnson subsidiary DePuy Orthopaedics, set out to change that with the introduction of the Attune Knee System, an integrated knee replacement solution designed with the needs of patients, surgeons, and hospitals in mind. However, the response to the DePuy Attune Knee System has been mixed. Some patients experience pain relief and improved mobility, while others report serious side effects and premature device failure.
If you're considering a knee replacement surgery and your doctor recommended the Attune Knee System, or you're already living with an Attune Knee implant, here's what you need to know.
About the DePuy Attune Knee System
Hailed by DePuy Orthopaedics as “a knee that can help patients get back sooner,” the Attune Knee System was developed over a six-year period as the result of the company's largest ever research and development project. The artificial knee replacement system features the latest in engineering and kinematics, and is available in both fixed bearing and rotating platform models.
The DePuy Attune Knee System also boasts proprietary technologies, such as:
- The Attune Gradius Curve: a gradually reducing radius designed to deliver improved anterior/posterior stability
- The Sofcam Contact: an innovative S-curve design that reduces stress on the implant and provides stability through flexion
- Logiclock Tibial Base: a locking design that reduces implant wear and tear
- Glideright Articulation: a design that optimizes patella tracking and accommodates patient variations
The Attune Knee System also has high flexion features which allow the implants to bend up to 150 degrees, making this artificial knee replacement system particularly attractive to younger knee replacement patients with active lifestyles.
Attune Knee System Timeline
- 2007: DePuy Orthopaedics launches largest-ever research and development project that will result in the creation of the Attune Knee System
- 2010: DePuy applies for and is granted pre-market approval for the Attune Knee System from the U.S. Food and Drug Administration (FDA) on the basis that it is substantially similar to knee replacement systems already on the market
- 2011: The FDA approves femoral head components and fixed bearing inserts for the Attune Knee System
- 2013: DePuy introduces its new, fixed bearing Attune Knee System
- 2014: DePuy introduces rotating platform knee and anatomic patella technologies for the Attune Knee System
- 2015: The FDA issues a recall for the Attune Knee Tibial Articulation Surface instrument after determining that a wire spring coil component can detach and potentially remain in the patient
- 2016: Attune Knee System patients report experiencing serious side effects and complications, including premature device failure
- 2017: A study published in the Journal of Knee Surgery finds that the Attune Knee implants have an unusually high rate of early failure of the tibial component at the implant-cement interface
Were You Injured by the Attune Knee System?
