DePuy Synthes Joint Reconstruction introduces two new knee technologies at EFORT

DePuy Synthes Joint Reconstruction announced in June the introduction of two new technologies for the ATTUNE® Knee System – the ATTUNE Rotating Platform and the Medialized Anatomic Patella. The announcement was made in conjunction with the 15th EFORT congress in London.
“The new ATTUNE Rotating Platform Knee and the Medialized Anatomic Patella provide additional options for patient care,” said Gary Lancaster, Knee Marketing Director at DePuy Synthes. “Offering the ATTUNE Knee with both fixed bearing and rotating platform options is important from the standpoint of surgeon preference and expertise, as well as individual needs of patients.”

The advantage of rotating platform knees is that the bearing can rotate as the knee flexes, which allows for a more natural motion and may also reduce the stress and wear on the implant1. The ATTUNE Rotating Platform Knee builds on DePuy Synthes Joint Reconstruction’s strong leadership in rotating platform knees and combines that expertise with the proven technologies of the ATTUNE Knee, which is designed to enhance stability and motion.

Studies show that between 10-20% of knee replacement patients are not completely satisfied with their knee replacement2. A major contributing factor to this is anterior knee pain in the area of the patella3. The Medialized Anatomic Patella was created to help address this need as it is designed to wrap around the knee in a more natural way and improve patellar tracking.
The ATTUNE Knee System, the largest research and development project in the history of DePuy Synthes Joint Reconstruction, was designed to provide better range of motion and address the unstable feeling some patients experience during everyday activities. To date, more than 41,000 ATTUNE Knee implants have been provided for patients worldwide4.
