Analysis of factors that affect the precision of the radiographic lateral femoral bowing angle using a three-dimensional computed tomography-based modelling technique

Table 2 Relationship of groups A and B according to arc plane and sagittal plane angle, flexion contracture and varus and valgus deformity

	Angle between arc plane and sagittal plane	Flexion contracture	Varus and valgus deformity
<5° group A	19.05 ± 7.85	9.59 ± 7.99	2.20 ± 1.83
>5° group B	24.39 ± 14.07	11.20 ± 6.97*	4.17 ± 2.20**
p	0.327	0.221	0.03

*A significant difference between groups was considered for p < 0.05. When the radiographic RLFB angle is greater than 5°, the flexion contracture angle has strong linear positive correlation with the RLFB angle (r = 0.535, p < 0.05)
Comparing the angle of sagittal plane and arc plane, it is found that there is no statistical difference between the two groups (p = 0.327)
**When RLFB is greater than 5°, it has no linear correlation with the varus and valgus deformity, but there are statistical differences in the varus and valgus deformity between two groups (p = 0.03)
