Research project: Large scale population based finite analysis of cementless tibial tray fixation

Currently Active: 

This project developed a method allowing population based assessment of joint replacements, focussing on the tibial tray component of a total knee replacement.

To generate a large population of models for finite element analysis, two statistical models were used. One was of the tibia, capturing both the variability of the morphology and bone quality, and the other was of the internal knee loads during a gait cycle. Assessment of the statistical models showed that they could adequately generate representative tibiae and gait cycle loads. An automated method was then developed to size, position, and implant the tibial tray in the generated population of tibiae in preparation for finite element analysis.
