FAI(FemoroAcetabular Impingement)
FAI Part I : Epidemiologic study associated with
Sport injury
FAI is considered to be a pre-arthritic condition
prevalence of FAI as a clinical diagnosis is estimated
to be 10% in a general adult population
Athletes have been more often associated with FAI
than ordinary patients

Introduction
Philippon MJ Clin Sports Med 2006
There has been increased reports evaluating the
relationship between sports activity and prevalence of FAI
1. To determine the prevalence of symptomatic FAI in
athletic patients
2. To find out the most common type of sport in Korea
Purpose of this study
422 hips (388 patients) of FAI
Retrospective study
July, 2003 ~ May, 2013 (10 yrs)
All cases were done arthroscopic Tx due to FAI Sx by one
surgeon (DS Hwang)
Material & Methods
Inclusion criteria
associated sports as we defined who underwent
arthroscopic surgery due to FAI
Exclusion
Insufficient radiographs or records
High energy hip trauma,
previous hip surgery
Tönnis Grade 2 or above
Proliferative disease of hip
LCPD
DDH etc
Material & Methods
2
60 hips in 50 patients were excluded
Mean age at surgery : 37.3 yrs (16~70 yrs)
362 Hips (338 patients)
M : F = 229 : 109
Material & Methods
History of sport activity
Duration of excise- at least, more than 2 hour/day, more than
3 times/week, more than 1 year
% associated with sport activity
Incidence at Age/Sex
Prevalance & Type of most common sport activity at ages
Type of FAI( Mixed, Cam, Pincer)
Material & Methods
Radiologic evaluation of FAI
Alpha angle
Head neck offset
Cross over sign(figure of 8 sign)
Coxa profunda, acetabular protrusio
3D-CT
Geographic bony deformity
MRA, if needed
Assessment of cartilage, labrum, synovium, cyst
Material & Methods Headneck offset
α angle
Results
Incidence at Age, Sex & Type of FAI
Most common at ages 20s, 40s
Male is most common at 20s, relatively more at 40s
