Multiple linear regression analysis of factors affecting the change in tibial rotation after uniplane OWHTO in all included subjects.

Dependent variables	Independent variables	Non-standardized coefficients B	SE	Standardized coefficients β	t value	P value
TRA	Constant	−4.609	2.272	–	−2.028	.061
	∆MPTA	0.860	0.248	0.667	3.465	.003*

The variables that are statistically correlated with the change in TRA were determined using multiple regression analysis with a stepwise method. The criterion for enrollment in the model was a P value of < .1. If the variable has a P value of > .1, the independent variables were excluded from the model.

B = unstandardized coefficients, MPTA = medial proximal tibial angle, SE = standard error, TRA = distal tibial rotation angle, β = standardized coefficients, Uniplane OWHTO = uniplane medial open-wedge high tibial osteotomy.
