Abstract A finite element model has been developed to predict in vivo micro motion between a modular acetabular cup and liner after cement less total hip arthroplasty.The purpose of this study is to experimentally validate the model.Six LVDT sensors were used to monitor the micromotion of read more the liner when subjected 2014 dodge ram 1500 fender flares to loading conditions ranging from 250 N to 5000 N.

Deformations at points of interest for both the experiment and FEM were compared.Results of the FEM with different coefficient of friction between the liner and the cup were investigated to correlate with the experimental results.
