Q1–Q3 Interquartile range, HKA Hip–knee–ankle, mLDFA mechanical lateral distal femoral angle (o in valgus), mMPTA mechanical medial proximal tibial angle (o in varus), JLCA joint line convergence angle, CORA-tibia centre of rotation angulation of tibia in varus. p < 0.05 was considered statistically significant
