Femorocetabular impingement (FAI) is a mechanical abutment in the hip joint due to a changed morphology and believed to be a risk factor for osteoarthritis (OA). The number of surgeries have rapidly increased, although the connection to OA lacks evidence. FAI definition is deficient and morphological changes is common in asymptomatic individuals. The alpha angle is a measurable radiological sign for FAI. Reduced Range of motion (ROM) and isometric strength have been reported in some cases. Knowledge of the functional impairments associated with FAI is needed as a first step, before designing a physiotherapy treatment program. The aim was to assess whether the alpha angle was associated with hip ROM and isometric strength of the hip in individuals with longstanding hip/groin pain. Secondary aim to assess if there were gender differences in ROM and isometric strength. Forty-six patients with unilateral hip/groin pain >3months, age 18-55 years, no previous hip surgery, or osteoarthritis were included in this cross-sectional study. The patients were examined with X-ray, ROM and isometric strength tests. Statistical analysis were performed by ANCOVA with gender as covariate to evaluate groups with alpha angle ≥60º and gender differences. No significant differences were observed in ROM or isometric strength between groups. The group with an alpha angle <60º group tended to have increased ROM in abduction and internal rotation in neutral. Women had greater ROM in internal rotation in neutral and in internal rotation in 90º flexion and a tendency to differ in flexion compared to men. Men were stronger than women in all isometric strength directions. No significant differences were observed in ROM or isometric strength between groups with an alpha angle ≥60º, though a tendency to differ in abduction and internal rotation in neutral. This pilot-study´s methodology is adequate for future research, preferably with larger samples sizes.
