This page contains a literature review of currently available knee models based on finite element analysis. The [http://www.imagwiki.org/mediawiki/index.php?title=Working_Group_10#Standards_Proposal Standards proposal], developed by [http://www.imagwiki.org/mediawiki/index.php?title=Working_Group_10 Working Group 10 - Model Sharing and Standards] of [http://www.imagwiki.org/mediawiki/index.php?title=Main_Page Interagency Modeling and Analysis Group] is specialized for knee modeling, as a guideline for the review process.
