Morphological and Biomechanical Insights into the Pathophysiology of Femoroacetabular Impingement Syndrome

PROJECT SUMMARY By some estimates, femoroacetabular impingement syndrome (FAIS) accounts for 82% of hip osteoarthritis (OA) cases. FAIS patients present with a loss of sphericity of the femoral head, reduction in femoral-neck offset, and/or an excessively prominent acetabular wall. Patients report pain that is position- or motion-related. Often, cartilage is delaminated from bone and the labrum is torn. The theory of FAIS pathophysiology is that pathoanatomy causes pathomechanics. However, we lack a quantitative understanding of the disease. Studies that have examined hip anatomy and biomechanics in FAIS patients have yielded conflicting data, likely due to the application of inaccurate…
