The range of the required anterolateral cortex osteotomy distance varied widely in biplanar open wedge high tibial osteotomy

Table 2 CT data

	Basic setting	Flange thickness is one-fourth of the anteroposterior tibial diameter	Angle between the transverse and ascending cuts is 120°
Required anterolateral cortex osteotomy distance, mm	9.4 ± 4.6 (− 1.5 – 20.3)	14.9 ± 5.1 (3.2 – 24.4)^a	15.2 ± 5.1 (0.8 – 24.4)^a
Angle between the two ascending cut planes, °	8.4 ± 3.6 (− 2.1 – 14.8)	12.2 ± 3.6 (2.3 – 21.5)^a	13.0 ± 3.9 (0.8 – 22.9)^a

Data are presented as the mean ± standard deviation with the range in parentheses
^aSignificant difference compared with basic setting, P < 0.001
