Johnson & Johnson Medical Devices Companies has announced that DePuy Synthes is launching the ATTUNE Cementless Knee in a rotating platform option in certain global markets.
“The ATTUNE Cementless Knee has the same great kinematic features of the cemented ATTUNE Knee, but I feel the cementless technology is a better alternative for my younger and more active patients who have healthy, strong bones,” said Ryan M. Nunley, M.D., Associate Professor and Fellowship Director at Washington University Orthopedics, Barnes Jewish Hospital. “These patients have the potential to remain active for many decades, and I think the evidence is growing that cementless knees have good long-term durability. I’ve implanted more than 400 ATTUNE Cementless Knees in my practice with excellent early results.”
As stated in the press release, “As with the cemented primary and revision systems, the ATTUNE Cementless Knee features several patented technologies designed to improve knee function. These include the ATTUNE GRADIUS Curve to provide stability through the range of motion and GLIDERIGHT Articulation to more accurately replicate the normal relationship between the patella (knee cap) and femur.”
“In developing the ATTUNE Cementless Knee, DePuy Synthes drew on the successful clinical history and legacy of its cementless and rotating platform technologies, including the LCS Cementless Knee which features POROCOAT Porous Coating which allows for biologic fixation.”
“The ATTUNE Cementless Knee is initially being launched in the United States, select countries in Europe, Japan, Australia and New Zealand, with additional launches to follow. It is available in a Cruciate Retaining and Posterior Stabilized Rotating Platform construct as well as a hybrid construct (cementless Femoral Component with a cemented Fixed Bearing or Rotating Platform Tibial base).”
Rajit Kamal, vice president and global franchise leader, Knees, DePuy Synthes, described some of the features of the cementless Attune knee to OTW, “There are several patented technologies that are part of the ATTUNE Knee and are meant to return patients to freedom and movement.”
“Among these are ATTUNE GRADIUS Curve, which is designed to address the unnatural sliding of the femur on the tibia to provide smooth motion and stability for everyday activities like going up and down the stairs and getting up from a chair. Another patented technology is GLIDERIGHT Articulation which is designed to enable the ATTUNE Knee design to more accurately replace the normal patella-femoral kinematics of the native knee so that the patient’s movements may be as smooth as possible.”
“Cementless knee surgeons who use rotating platform now have a device that combines the technologies of the ATTUNE Knee and learnings from our clinically successful predicate devices, including the LCS COMPLETE Knee System.”
“The patented ATTUNE Knee technologies as well as our leadership in rotating platforms and long history with POROCOAT, which allows for biologic fixation, differentiate ATTUNE Cementless from other cementless technologies on the market.”
