Important Definitions • Instability: the mechanical environment at the rim in acetabular dysplasia – Shearing stresses on cartilage – High loads on rim
Important Definitions • Femoro-acetabular impingement: abnormal dynamic contact/”conflict” between the proximal femur and acetabular rim, and the adjacent acetabular cartilage – FAI is a clinical diagnosis, NOT an imaging diagnosis
