AAOS: DePuy Synthes Launches Revision Fixed Bearing Tibial Base and Cemented Stem

DePuy Synthes, part of the Johnson & Johnson Family of Companies, announced the launch of the first ATTUNE Knee revision options, the ATTUNE Revision Fixed Bearing Tibial Base and the 14 x 50 mm Cemented Stem. The Tibial Base is designed to address a range of patient needs, from complex primary to partial revision of ATTUNE Primary Knees. The announcement was made in San Diego, Calif., coinciding with the American Academy of Orthopaedic Surgeons Annual Meeting.
 
The ATTUNE Revision Fixed Bearing Tibial Base, which is compatible with either fixed bearing posterior stabilized or cruciate retaining tibial inserts, incorporates the proprietary technologies of the ATTUNE Knee such as the LOGICLOCK Tibial Base locking mechanism that is designed to enable enhanced kinematics, stability and wear reduction.¹ The ATTUNE Revision Fixed Bearing Tibial Base can be used with a 14 x 50 mm Cemented Stem that can be added intra-operatively at the discretion of the surgeon for patients with clinical needs that require supplemental fixation.
 
According to Rajit Kamal, global knee platform leader, DePuy Synthes Joint Reconstruction, “DePuy Synthes worked with renowned experts around the world to develop the ATTUNE Knee System. The ATTUNE Revision Fixed Bearing Tibial Base and Cemented Stem were developed to address more complex clinical needs and expand treatment options for patients. It will also extend DePuy Synthes leadership in the category of revision solutions.”
 
DePuy Synthes Companies developed the ATTUNE Knee System to improve the stability and motion of knee replacement, which are important to patient satisfaction. The ATTUNE Knee System can help patients return to their normal activities sooner than anticipated^2-3, while also enabling surgeons and health systems to improve clinical outcomes, reduce costs, and increase patient satisfaction.
 
Implant survivorship data from the 2016 Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) confirmed positive early results for the primary ATTUNE Knee.⁴ These data add to other recent registry evidence which has shown that survivorship for the primary ATTUNE Knee compares favorably to other knee systems in its class.⁵ In addition, one-year results from two worldwide studies have shown improved patient reported outcomes measures with the primary ATTUNE Knee compared to other leading knee systems.⁶
