DePuy Synthes introduces ATTUNE Revision Knee System to provide stability in motion

Comprehensive revision system designed to address broad range of Complex Primary and Revision procedures

DePuy Synthes, part of the Johnson & Johnson Medical Devices Companies, today announced the Europe, Middle East and Africa launch of the ATTUNE Revision Knee System, to complement the ATTUNE Primary Knee System and provide surgeons with a comprehensive solution for knee replacement. The ATTUNE Revision Knee System is being unveiled at the 19^th European Federation of the National Associations of Orthopedics and Traumatology (EFORT) Congress, taking place in Barcelona, Spain.

While knee replacement is widely recognized as one of the most common and successful surgical procedures, according to registry data, approximately six percent of patients will require a revision surgery 10 years after the initial procedure. Revision surgeries are regarded as complex, particularly in cases where large bone defects present reconstruction and fixation challenges. The ATTUNE Revision Knee System aims to address some of those challenges through improved kinematics, fixation and patient fit. With both fixed-bearing and rotating platform options, it is one of the most comprehensive revision knee systems available on the market today.

“The ATTUNE Revision Knee System is a step forward for patients - the System feels like a primary total knee intraoperatively and patients experience a smooth range of motion,” said Mr Peter James, Consultant Orthopedic Surgeon, Nottingham City Hospital. “From a clinical perspective, the benefit of using the same system for primary and revision knee replacement procedures provides greater options for complex primary procedures and can lead to a smoother learning curve for surgeons and the wider hospital team.”

The ATTUNE Revision Knee System is designed to work in harmony with the patient’s anatomy to deliver stability in motion during activities such as stair ascent or descent, walking uphill or downhill or getting up from a chair through:

• ATTUNE GRADIUS Curve, designed to address the unnatural sliding of the femur on the tibia, to provide smooth motion and stability during everyday activities
• GLIDERIGHT^® Articulation, designed to enable the ATTUNE Knee design to more accurately replicate the normal patello-femoral kinematics of the native knee

“With the addition of the ATTUNE Revision Knee to our existing ATTUNE Knee System platform, we hope to be able to continue to improve knee replacements satisfaction rates for more patients across Europe, the Middle East and Africa,” said Torbjorn Skold, Vice President, DePuy Synthes EMEA Joint Reconstruction.

DePuy Synthes is committed to the continued evaluation of outcomes of the ATTUNE Knee System through its comprehensive ATTUNE Knee Evidence Generation Program that gathers information from national joint registries, investigator-initiated studies, independent studies and company initiated studies. Recent findings from a multicenter study of 200 cases from The Netherlands found that the ATTUNE Primary Knee System showed a statistically significant improvement in knee physical function at six months compared to preoperative baseline, using the Knee injury and Osteoarthritis Outcome Score- Physical Function Short Form (KOOS-PS). In addition, 80 percent of those ATTUNE Knee patients’ KOOS-PS improvements were realized by six months, with statistically significant improvements observed at intervals prior to six months. Also, pain and other PROMS were statistically significantly better at six weeks compared with pre-operative baseline. The same technologies that helped deliver these outcomes are also incorporated in the ATTUNE Revision Knee System, helping to address overall patient satisfaction.
