The analysis between RAD 90 and Group A, B, C, and D. RAD 90 in Group B at 60° flexion was significantly larger than that in Group A at 60° flexion (*p < 0.05). RAD 90 in Group D at 90° flexion was significantly larger than that in Group A at 90° flexion (*p < 0.05). RAD 90, the rotational angular difference between 90° flexion and maximum flexion
