Lower limb biomechanics in femoroacetabular impingement syndrome, asymptomatic cam morphology, and controls during bilateral and single-leg squatting

Key Points

Hip biomechanics during single-leg squatting may vary significantly among individuals with femoroacetabular impingement syndrome and those without symptoms.
Despite similar squatting depths, variations in hip flexion, rotation, and abduction moments can impact rehabilitation strategies.
Analysis of lower limb biomechanics focused on the differences and similarities in movements across distinct groups.
Targeting specific hip biomechanics could improve rehabilitation outcomes in individuals with cam morphology.

Abstract

The greater demands of SLS may require those with FAIS to perform it differently to those without symptoms, regardless of the presence of cam morphology. Given all groups squatted to a similar depth, hip biomechanics - including flexion, rotation, and abduction moments - may be a more relevant target for rehabilitation.
