Figure 9

The hrf orientation at peak loads of the CAS FF and the CON group was compared. Left: hrf orientation as a function of cup orientation, including linear regression lines (black: overall regression; green: regression line for CAS FF group; magenta: regression line for CON group). Blue cross: CAS FF, red plus: CON. Right: boxplot of the hrf orientation at peak loads for the CAS FF and the CON group. (a) Force inclination at t1, (b) force anteversion at t1, (c) force inclination at t2, and (d) force anteversion at t2.
