Morphological and Biomechanical Insights into the Pathophysiology of Femoroacetabular Impingement Syndrome

The project will examine three cohorts: FAIS patients, negative controls, and positive controls. Aim 1 involves measuring in-vivo hip articulation during inclined walking, pivoting, and squatting using dual fluoroscopy, followed by visualizing the interaction between hip joint shape and kinematic position during dynamic loading using statistical shape modeling. Aim 2 will analyze chondrolabral mechanics in-silico by generating finite element models of bone, cartilage, and labrum, comparing load transfer to the labrum and shear stresses/strains at the osteochondral and chondrolabral junctions during specific movements, and quantifying relationships between local hip shape measures and chondrolabral mechanics.
