Femoroacetabular impingement: fact, fiction, or fantasy?

Objective:
Proponents of femoroacetabular impingement (FAI) now claim that FAI is an important risk factor for hip osteoarthritis and argue that early, aggressive treatment is indicated to stave off long-term complications. The result is more young patients undergoing corrective surgery; does the literature support these claims or has hype trumped reality? This article critically reviews these assertions together with the current scientific evidence that defends (or refutes) them.
Conclusion:
Each reader will need to weigh the evidence carefully when interpreting images or planning management for patients with possible FAI.
