  1. Negative values indicate varus angulation.
  2. SD, standard deviation; MPTA, medial proximal tibial angle; LDFA, lateral distal femoral angle; PTS, posterior tibial slope; JLO, joint line obliquity; HKA, hip–knee–ankle angle; aHKA, arithmetic hip–knee–ankle angle.
  3. *Statistically significant at p < 0.05
