Abbreviations: CHJP, Chronic hip joint pain; FVMRI, femoral version by MRI; deg, degrees; ROM, range of motion; ER90°, external rotation ROM with hip flexed to 90°; IR90°, internal rotation ROM with hip flexed to 90°; ER0°, external rotation ROM with hip in neutral flexion/extension; IR0°, internal rotation ROM with hip in neutral flexion/extension; ROMdif90°, difference in ROM with hip flexed to 90°; ROMdif0°, difference in ROM with hip in neutral flexion/extension

^*Data from one participant with CHJP was omitted secondary to pain limiting endrange of motion.

^†ROM difference was calculated by subtracting ER ROM from IR ROM
