Multivariate Quantitative Outcomes of Periacetabular Osteotomy Using Discrete Element Analysis.

ABSTRACT: Introduction: Multiple biomechanical models have been suggested to quantify lower limb joint contact stress distributions, with varying results. Among others, the choice of cartilage morphology and gait loading patterns can significantly affect simulation results. Moreover, there is currently no consensus on simulating the input and output data needed to obtain reliable results and enable a comprehensive analysis. Objectives: The aim of this study was to compare the reliability and clinical relevance of joint contact metrics by calculating pre- and postoperative hip joint contact stress distributions of a dysplastic cohort under various simulation scenarios. Methods: A cohort of 22 dysplastic patients has been treated using periacetabular osteotomy (6-month follow-up).
