Limited Hip Rotational Range of Motion Is Associated with Kinesiophobia in Patients with Femoroacetabular Impingement

Background The severity of acetabular cartilage or labral injuries does not always correspond with clinical symptoms. This observational, cross-sectional study aimed to investigate the association between kinesiophobia levels and clinical findings in patients with femoroacetabular impingement syndrome. Methods Twenty-two individuals with symptomatic femoroacetabular impingement syndrome (12 females, 10 males; aged 18–65 years) were included in the study. Radiographic assessments comprised the alpha and the lateral center-edge angle. Kinesiophobia was assessed using the Tampa Scale for Kinesiophobia (TSK), pain intensity with the Visual Analog Scale, and pressure pain threshold using an algometer. Hip range of motion was measured using the Clinometer mobile application, hip function with the Harris Hip Score, and lower-extremity strength with the 30-Second Sit to Stand Test. Results A statistically significant inverse relationship was observed between kinesiophobia levels and hip external rotation (p = 0.006) and internal rotation range of motion (p = 0.027). Kinesiophobia levels were also significantly associated with the Harris Hip Score (p = 0.012). However, no relationship was found between kinesiophobia levels and the lateral center-edge angle (p = 0.824) or the alpha angle (p = 0.150). Additionally, no association was identified between the 30-Second Sit to Stand Test and either the lateral center-edge angle (p = 0.967) or the alpha angle (p = 0.943). Conclusions Kinesiophobia was significantly associated with hip rotation range of motion and functional status, whereas radiographic measures showed no meaningful clinical relevance.
