Influence of Pelvic Tilt on Polyethylene Wear after Total Hip Arthroplasty

Table 3

Multiple regression analysis between conventional polyethylene wear rate and factors of pelvic tilt angle (PTA) and the angle of inclination and anteversion of the cup.

Position	Parameter	Adjusted	Regression coefficient	Standard regression coefficient (β)	p
Supine	PTA	0.09	0.004	0.292	0.04
	Cup inclination		0.005	0.398	0.01
	Cup anteversion		0.02	0.03	0.54
Standing	PTA	0.16	0.002	0.388	0.03
	Cup inclination		0.002	0.417	<0.01
	Cup anteversion		0.03	0.085	0.59
