Range of motion
knee in flexion (bottom left) and knee
Patients had a median maximum passive hip flexion with the knee in flexion of 120° (range 115–140°) on the operated side and 120° (range 115–150°) on the contralateral side (Box plots showing the median and interquartile range of the maximum passive hip flexion with the knee in flexion (top left) and maximum passive hip flexion with the knee in extension (top right) of the injured and contralateral leg; scatter plots showing the relationship between maximum hip flexion of the injured and contralateral leg with knee in flexion (bottom left) and knee in extension (bottom right)
