Estudio Comparativo del Comportamiento del Zylon con el de Materiales Utilizados Tradicionalmente en la Fabricación de Prótesis de Rodilla Tricompartimentales

Abstract

The present technical study, consists in the analysis of the properties of zylon to determine if it is feasible to manufacture tricompartmental knee prosthesis for first intention surgery, knowing that this new material introduced few years to mundial market, zylon has excellent mechanical properties with a lower cost than the materials currently used in prosthetics and is much lighter than them. The study is to be applied in the Ecuadorian market, proving that it is possible to manufacture internal prosthetics with 3D printing in order to supply the demand of these elements in the Ecuadorian medical industry, knowing that there are about 2,700,000 older adults who have problems in articulations in the country (according to data from the 2009 census of INEC) and are possible candidates for total or partial knee arthroplasty. The properties will be analyzed based on the medical and mechanical requirements, the properties will be of three tricompartmental knee prostheses with similar characteristics in terms of their functionality, flexion angles and costs. The information about similar implants and normalized information comes from makers' catalogs, technical data of the CES EduPack 2013 library and the corresponding ISO and ASTM standards.
