Prevalence of femoro-acetabular impingement in non-arthritic patients with hip pain: a meta-analysis.

Femoroacetabular impingement should be suspected in 47 to 74% of patients with hip pain and without arthritis. Physicians must maintain a high index of suspicion for FAIS in young patients presenting with hip pain, as FAIS is a common and treatable condition that, if left alone, may lead to hip degeneration.
