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 natio celebrate eyeshadow palette experimentally validate the model.Six LVDT sensors were used to monitor the micromotion of the liner when subjected 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 bostik universal primer pro correlate with the experimental results.
