Zimmer Holdings Launches Personalized Knee System
Zimmer Holdings, Inc. introduced Persona, the Personalized Knee System.
In a release, the Company noted that the Persona System ushers in a new era in total knee replacement, combining personalized implants with intelligent instrumentation to provide surgeons with a new level of intraoperative precision to customize the best fit for their patients.
"The Persona System is the most comprehensive, anatomically accurate and highest fidelity knee replacement system ever designed," said Jeff McCaulley, President, Zimmer Global Reconstructive, in a release. "Zimmer scientists and engineers and their designing surgeon partners pushed the boundaries of implant design, drawing upon advanced morphology, physiology, kinesiology and material sciences to develop a truly revolutionary system that allows surgeons to provide each patient with a personalized fit."
Zimmer's Bone Resection Atlas is a bone atlas with virtual resection and component placement capabilities. This tool allowed the Persona System's 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 allows 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 uses a six-axis, high-precision robot to replicate the kinematic patterns and biomechanical forces for a range of patient daily activities.
The Persona System incorporates Zimmer's Vivacit-E bearing surface material.
"The instrumentation for the Persona System was specifically designed to provide surgeons with a new level of precision in order to take full advantage of the fidelity of the Persona implants," said Steve White, General Manager and Vice President, Knees at Zimmer. "Surgeons told us that to create a more natural feeling, normal functioning knee for patients, we needed to develop implants and instruments that enable a more precise intraoperative fit and feel."
Zimmer designs, develops, manufactures and markets orthopaedic reconstructive, spinal and trauma devices, dental implants, and related surgical products.
