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.

Studies on FEA of the Knee

Open Knee

The finite element representation used in the Open Knee projects is reviewed in here as an example. This will also serve an ongoing assessment of the scholarly status of the knee model under development.
