Fig. 3

Kinematic and contact point analysis of the flexion phase. a Presents the lateral fluoroscopic images. b Presents the bone models adjusted to match the lateral fluoroscopic images. The red area of c is the contact area, and the white point is the contact point that is the geometric centre of the contact area. The number 1 represents the starting position of kneeling activity, the number 2 represents the middle of flexion of the knee, and the number 3 represents the maximum flexion of the knee
