Hip ROM measures were flexion, internal and external rotation at 90\u00b0 of hip flexion, total rotation (internal and external), and bent-knee fall out (BKFO). Cam morphology was determined from anteroposterior pelvis or 45\u00b0 Dunn radiographs, defined by an alpha angle \u226560\u00b0. Linear regression models with generalized estimating equations were used to examine the relationship between group (symptomatic and asymptomatic) and each ROM measure. Interaction terms (group \u00d7 cam morphology or group \u00d7 sex) were included to examine if relationships between group and hip ROM were influenced by cam morphology or sex. Where appropriate, models were adjusted for sex, age, and cam morphology.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>An interaction between the relationship between group \u00d7 cam and internal rotation ROM was found. Symptomatic players with cam morphology had lower internal rotation ROM than controls with cam morphology (adjusted mean difference [AMD] = \u22124.5\u00b0; 95% CI, \u22127.4\u00b0 to \u22121.6\u00b0). Hip\/groin pain was not associated with internal rotation ROM if cam morphology was absent. A significant interaction was also found for group \u00d7 sex and BKFO and total rotation ROM. Symptomatic women had lower total rotation ROM than control women (AMD = \u22128.2\u00b0; 95% CI, \u221214.1\u00b0 to \u22122.2\u00b0), but no difference was seen in men. BKFO range was lower in men with hip\/groin pain compared with control men (AMD = 1.6 cm; 95% CI, 0.3-3.0 cm), but no difference was seen in women. Flexion and external rotation ROM did not differ between symptomatic and control hips.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Cam morphology was an effect modifier of the relationship between hip\/groin pain and internal rotation ROM.
