The association between femoroacetabular impingement and sitting positions: A three-dimensional simulation study

To investigate the relationship between femoroacetabular impingement (FAI) and different sitting positions. We retrospectively reviewed 24 patients with FAI. Femoral and pelvic parameters were measured, and 3D simulation software was used to create and analyze a 3D model of the hip. The data were divided into impingement and non-impingement groups according to whether impingement occurred in the normal or cross-legged sitting positions. The...
