Zimmer Holdings Inc. introduced Persona, The Personalized Knee System, at the American Academy of Orthopaedic Surgeons Annual Meeting. According to a company press release, the system combines personalized implants with intelligent instrumentation to provide surgeons with a new level of intraoperative precision to customize the best fit for their patients.

Knee replacement did not affect contralateral knee loading at ... “The Persona System is the most comprehensive, anatomically accurate and highest fidelity knee replacement system ever designed,” Jeff McCaulley, president, Zimmer Global Reconstructive, stated in the release. “Zimmer scientists and engineers and their designing surgeon partners pushed the boundaries of implant design, drawing upon advanced morphology, physiology, and kinesiology and material sciences to develop a truly revolutionary system that allows surgeons to provide each patient with a personalized fit.” Among the technologies that went into the design of new knee system were: - Zimmer’s Bone Resection Atlas, which allowed surgeon designers and engineers to study the morphology of hundreds of bones, representing a diverse global population, to precisely define anatomically accurate implant shapes and sizes. - Zimmer’s Virtual Biomechanical Knee is a kinematic computational analysis program that allowed rapid testing of hundreds of different design options to virtually assess their impact on soft tissues, motion and overall performance to optimize designs that more closely replicate natural feel and normal function. - Zimmer’s Robotic Simulator used a six-axis, high-precision robot to replicate the kinematic patterns and biomechanical forces for a range of patient daily activities, validating the fidelity, precision and robustness of the implant designs. The new system also includes the Vivacit-E advanced bearing surface material, incorporating vitamin E, for increased strength, ultra-low wear and oxidative stability for long-term performance. Trabecular Metal Technology porous metal is available on every compartment of the new knee system. Zimmer also introduced a range of patient-specific instrumentation with the system, including the iASSIST Knee, The Personalized Guidance System and the eLibra Dynamic Knee Balancing System. “We designed the Persona System to meet the demands of today’s patients and provide unmatched surgical precision for surgeons, all in the context of concerns about the total cost of care. The Persona System was designed to help hospitals deliver high-quality, consistent outcomes while reducing total costs,” McCaulley said.
