Multivariate logistic regression analysis

Dependent variables	Significant variables	Odds ratio	P value	95% CI
Participants with or without tight EG, n = 103 patients	MTSA, °	1.060	0.560	0.88–1.27
	HKAA, °	0.976	0.617	0.89–1.07
	FCA, °	1.130	< 0.001*	1.05–1.20
	Active maximum flexion angle, °	0.992	0.571	0.96–1.02

The statistical analysis was performed using the forward stepwise method. EG extension gap, MTSA medial tibial slope angle, HKAA hip knee ankle angle, FCA flexion contracture angle, CI confidence interval; (*) statistically significant (P < 0.05).
