  1. aCI indicates confidence interval
  2. Bold values are statistically significant, P < 0.05
  3. mLDFA mechanical lateral distal femoral angle, mMPTA mechanical medial proximal tibial angle, SDA screw divergence angle
  4. Genu angular deformity type: Genu valgus vs. genu varus
  5. Aetiology: Idiopathic vs. non-idiopathic
