Inverted Rearfoot posture in subjects with coexisting patellofemoral osteoarthritis in medial knee osteoarthritis: an exploratory study

Table 3 Results of binary logistic regression analysis of the association between calcaneus inverted angle and the presence of PFOA (n = 68)

Independent variable	Dependent variable	Odds ratio (95% CI)*
Independent variable	Dependent variable	Crude model	Propensity adjusted model
Calcaneus inverted angle, per degrees	No PFOA (n = 30) vs. ANY PFOA (n = 38)	1.118 (1.018–1.245) ^†	1.134 (1.013–1.291) ^†
	No PFOA (n = 30) vs. MIXED PFOA (n = 19)	1.166 (1.031–1.356) ^†	1.135 (0.958–1.406)
	No PFOA (n = 30) vs. MEDIAL PFOA (n = 22)	1.180 (1.044–1.368) ^††	1.180 (1.005–1.439) ^†
	No PFOA (n = 30) vs. LATERAL PFOA (n = 26)	1.109 (1.010–1.235) ^††	1.078 (0.965–1.213)

PFOA: patellofemoral osteoarthritis; 95% CI: 95% confidence interval
*Adjusted for propensity to prescribe as a function of age, (continuous), sex (0: male, 1: female), body mass index (continuous), tibiofemoral joint Kellgren/Lawrence grade (continuous), corrected anatomical axis angle (continuous), presence of varus thrust (0: absence, 1: presence), and knee flexion range of motion (continuous)
