Abstract

Objective　To explore the effects of rotation position change of lower limbs on the femoral valgus angel (FVA) measurement of different forms of femur and to improve the safety of knee replacement surgery based on the quantitative analysis of the FVA and femoral bending angel (FBA) in patients from southern China. Methods Computed tomography angiography (CTA) scan data of 75 patients (113 sides) without osteoarthritis (OA) in our hospital were collected. Femoral bowing angle (FBA) and femoral valgus angle (FVA) were measured by 3D reconstruction and location.. The following four groups were divided according to FBA: a severe varus deformity group: FBA>4°; a mild varus deformity group: 1°0.05). Conclusions　Valgus or varus deformity of femoral shaft has direct influences on the value of FVA. The measurement of FVA should always consider the influence of femoral shape and rotation angle.

Key words
