  1. M1 was the distance of the inward/outward movement in AP X-ray of the distal bone fragment relative to the proximal bone fragment; M2 was the forward/backward movement in lateral X-ray between the two bone fragments; β1 was the angle of varus/valgus in AP X-ray of the distal bone segment relative to the mechanical axis of the proximal bone segment; β2 was the angle of extension/flexion in lateral X-ray between the two bone fragments.
  2. aData and bData are presented as Median (P25, P75)
  3. *P values were calculated using Mann-Whitney U test
