In this paper, we focus on the design of orthopaedic implants that fit a maximum percentage of the target population, both in terms of geometry and biomechanical stability. CT scans of the bone under consideration are registered non-rigidly to obtain correspondences in position between them. A statistical model of shape is computed by means of principal component analysis. A method to automatically propagate standardize fractures on the statistically-based bone population has been developed as well as tools to optimize implant position to best-fit the bone surface. Afterwards, finite element analysis is performed to analyse the biomechanical performance of the bone/implant construct. The mechanical behaviour of different PCA bone instances is compared for tibia representing the Asian and Caucasian populations.","license":"You are licensing your work to Kitware Inc. under the\nCreative Commons Attribution License Version 3.0.\n\nKitware Inc. agrees to the following:\n\nKitware is free\n * to copy, distribute, display, and perform the work\n * to make derivative works\n * to make commercial use of the work\n\nUnder the following conditions:\n\\\"by Attribution\\\" - Kitware must attribute the work in the manner specified by the author or licensor.\n\n * For any reuse or distribution, they must make clear to others the license terms of this work.\n * Any of these conditions can be waived if they get permission from the copyright holder.\n\nYour fair use and other rights are in no way affected by the above.\n\nThis is a human-readable summary of the Legal Code (the full license) available at\nhttp://creativecommons.org/licenses/by/3.0/legalcode","keywords":["Finite Element","Statistical Modeling","PCA","Biomechanical","Bone Fracture","Implant Fitting","Peri-Articular Plate"],"authors":[{"name":"Bonaretti, Serena","email":"serena.bonaretti@istb.unibe.ch","affiliations":["University of Bern, Switzerland"],"corresponding":true},{"name":"Reimers, Nils","affiliations":[]},{"name":"Reyes, Mauricio","affiliations":[]},{"name":"Nikitsin, Andrei","affiliations":[]},{"name":"Joensson, Anders","affiliations":[]},{"name":"Nolte, Lutz-Peter","affiliations":[]},{"name":"Buchler, Philippe","affiliations":[]}],"date_submitted":"2008-05-01T00:00:00Z","external_publication_id":554,"revision_cids":["bafkreifzvhgxfcaksaqxncdlghpjgc4fkyjnqok7z7hvctmbkvyqm25w4a"]},"mdast":{"type":"root"},"downloads":[{"url":"https://ipfs.desci.com/ipfs/bafkreial23mqdt7lzd7kcfsixkrzjbd627fgv46bqwa6lof3wzt3gsf5au","title":"root/reviews.md","filename":"reviews.md","extra":{"size_bytes":2587,"type":"file"}},{"url":"https://ipfs.desci.com/ipfs/bafkreibvs74pkiu4ke45r5t5q7hyvupmwj435mnpfeupy2ws7nlf6ggwle","title":"root/insight-journal-metadata.json","filename":"insight-journal-metadata.json","extra":{"size_bytes":8756,"type":"file"}},{"url":"https://dweb.link/ipfs/bafybeibgzyjg7byr7bf4ogptcvyqwb6hotrxrtxj56yr43jlnwqunxjxxe","title":"root/article.pdf","filename":"article.pdf","extra":{"size_bytes":3171205,"type":"file"}}],"references":{"cite":{"order":["ref1","ref2","ref3","ref4","ref5","ref6"]},"data":{"ref1":{"label":"ref1","enumerator":"1","url":"https://doi.org/10.1016/j.clinbiomech.2003.09.009","html":"Farron A.
