Impairments in patients with femoroacetabular impingement syndrome of different age groups

Femoroacetabular impingement (FAI) syndrome has been related to joint and muscle adaptations. Three different FAI patient age groups had their range of motion (ROM), strength and functionality compared. Although hip ROM and functionality were similar between groups, muscle strength was smaller for external rotators, abductors, flexors and extensors in the age group 40-49y compared to the groups’ 20-29y and 30-39y. This strength loss in age group 40-49y patients might be related to aging or with the early onset of osteoarthritis (OA).
