Fig. 3From: Effect of limb rotation on radiographic alignment measurement in mal-aligned kneesThe deviation range of HKA and FTA in patients with different flexion and coronal deformity. p value < 0.05 means that difference between the two corresponding groups is significant in 95\(\%\) confidence level. a Participants were divided into slight, moderate, and severe flexion groups by the degree of flexion contracture. The left part showed the HKA deviation range in the slight, moderate and severe flexion group. The right part showed the FTA deviation range in the slight, moderate and severe flexion group. b Participants were divided into slight, moderate, and severe coronal deformity groups by the degree of coronal deformity. The left part showed the HKA deviation range in the slight, moderate, and severe coronal deformity group. The right part showed the FTA deviation range in the slight, moderate and severe coronal deformity groupBack to article page
