The ATTUNE® Knee System is the largest ever research and development project from DePuy Synthes Joint Reconstruction. Novel testing protocols and methods were used during development. Each aspect of knee replacement design and surgical process was evaluated. And it was this rigorous process that has produced patented technologies to address the patient need for stability and freedom of movement. 6 years of development, implantations in over 9,000 patients1, and a series of innovative proprietary technologies: the ATTUNE Knee System is designed to feel right for the surgeon in the OR and right for the patient.
