- *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)
