Hip imaging has been transformed in the last 15 years: The discovery of femoroactabular impingement (FAI) as the major cause of early-onset osteoarthritis in non-dysplastic hips and the introduction of hip-preserving surgery with arthroscopic treatment of FAI has had a major impact on imaging.

What were the factors that drove this transformation in hip imaging? What do we know about FAI, and what is unknown? What are the strengths of hip imaging in diagnosing FAI, and what are the limits and controversies?

This introductory lecture (“Antrittsvorlesung”, in German) by Reto Sutter gives an overview of FAI and of the challenges faced by radiologists and orthopedic surgeons today. It can be accessed on YouTube:
