The main objective of this study is to predict cartilage contact pressures in the hip joint during simulated daily activities before and after periacetabular osteotomy (PAO) for correction of traditional dysplasia/retroversion using subject-specific finite element models. The effects of PAO on hip joint mechanics will be analyzed by comparing previously modeled pre-op scans (University of Utah IRB "Comparative Stress Analysis of Hip Dysplasia" #10983) to post-op model predictions in each loading scenario. The investigators study will consist of two key components: 1) CT acquisition- CT arthrogram to obtain post-operative data for generating subject-specific FE models after surgical treatment 2) Gait analysis- motion analysis to obtain subject-specific kinematics and kinetics to drive the FE model simulations post-operatively.
