What is Coronal and sagittal alignment of the lower limb in Caucasians: Analysis of a 3D CT database about?

Introduction: Lower limb alignment is a major determinant of long-term outcomes after osteotomy or total knee replacement. The aim of this paper is to define the mean values of coronal and sagittal lower limb alignment for Caucasians as a function of sex using 3D reconstructions from CT-scans. Materials and methods: The analysis involved 586 Caucasian patients (269 males and 317 females) who had their hip-knee-ankle angle (HKA), lateral distal femoral angle (LDFA), medial proximal tibial angle (MPTA), posterior proximal tibial angle (PPTA), lateral and medial proximal posterior tibial angles (LPPTA/MPPTA), posterior distal femoral angle (PDFA), and non-weightbearing joint convergence angle (nwJLCA) measured. This analysis was performed using a CT-scan-based modelling system (SOMA). Differences between sexes and morphotypes (neutral, varus and valgus) were analyzed statistically. Results: The mean HKA was 180 ± 2.57 • , LDFA 86.1 ± 1.87 • , MPTA 86.1 ± 2.15 • , PPTA 84.6 ± 2.58 • , LPPTA 84.9 ± 3.17 • , MPPTA 85.1 ± 3.21 • , PDFA 85.3 ± 1.50 • and nwJLCA 0.82 ± 1.32 • . There was a significant difference between sexes for the HKA (180.3 ± 2.46 • and 179.0 ± 2.52 • ), LDFA (85.6 ± 1.
