Correlation coefficients (r) between bisect offset, patella tilt angle, and measures of patella alta and morphologic features of the trochlea

Variable	ISR	MISR	SA	TA	LTI	MTI
Bisect offset	0.25*	0.15**	0.19*	−0.03	−0.38*	0.04
Patella tilt angle	0.08**	0.06	0.15**	−0.27*	−0.32*	0.05

* p < 0.0001, ** p ≤ 0.05; ISR = Insall-Salvati ratio; MISR = modified Insall-Salvati ratio; SA = sulcus angle; TA = trochlear angle; LTI = lateral trochlear inclination; MTI = medial trochlear inclination.
