In doing so, we confirmed This material is combined with a keeled design to deliver stable initial and biological fixation. Why Should I Register and Submit Results? http://myknee.se/en/ (pgs 42-43). A total score is calculated that ranges from 0 (worst knee problems) to 48 (no knee problems). Listing a study does not mean it has been evaluated by the U.S. Federal Government. Total knee systems are comprised of several different parts which mimic the anatomy of the knee. A vision requires leadership to become reality. Improvements in surgical techniques and implant materials have helped make total knee replacements one of the most successful procedures in all of medicine, according to the AAOS. Zimmer Biomet or its affiliates unless otherwise indicated, and must Select variants from the 2016 Swedish National Registry available at 2014). Recently, Zimmer-Biomet have introduced Persona Total Knee system with design changes that include asymmetric tibia plate, increased medial pivoting and more extensive choices in respect to poly thickness, all with the purpose to improve balancing, stability and longevity. Keywords provided by R.G.H.H. Therefore new implants are introduced to the marked with the theoretical benefit of improved implant survival and superior patient reported outcomes. Forward-looking statements speak only as of the date they are made, and Zimmer Biomet disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Femur specs:Anatomic design with21 distinct profilesin2mm There have been individual cohort studies, indirect comparisons and retrospective studies to test the efficacy of a variety of different total knee replacement devices but there are very few high quality investigations of new paradigms or significant design change. Women's US Size Chart doi: 10.1136/bmj.f7592. U.S. Department of Health and Human Services, The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Zimmer Persona knee implants are available as both cemented and uncemented implants. Nelissen, Leiden University Medical Center: Device: Persona PS Knee Prosthesis by Zimmer, Device: NexGen PS Knee Prosthesis by Zimmer. without the express written consent of Zimmer Biomet. that implant shape really matters. Trabecular Metal is made from the element tantalum. on Persona Sizing Plate Handle 14 Set Tibial Rotation 15 Verify Overall Alignment 16 . The Zimmer Persona was approved by the FDA through its 510(k) approval process in late 2012, nearly two decades after Zimmer's NexGen line was introduced in 1995. Zimmer said its goal was to come as close as possible to the remarkable mechanics of the human body and claimed the Persona would "put the person back in knee replacement."
