Total knee replacement implant based on normal anatomy and kinematics

摘要

A total knee replacement prosthesis is presented whose bearing surfaces are derived from an anatomically representative femur and a modified baseline tibial surface. The contacting femoral and tibial bearing surfaces include the inter-condylar as well as condylar regions. The modified baseline tibial surface is generated by modifying a baseline tibial surface. For example, the baseline tibial surface can be flattened mathematically to generate the modified baseline tibial surface.
