Radiographic Analysis^*

	Anterior Group (29 Patients)	Posterior Group (28 Patients)	Difference in Means (95% CI)	P Value
Femoral component position†(deg)	0.60 ± 1.6	0.70 ± 1.2	0.1 (–0.7-1.0)	0.81
Femoral component position in >2° of varus (% of patients)	15	19	3.8 (–16.7-24.4)	1.00
Acetabular abduction angle†(deg)	48.5 ± 3.3	46.9 ± 5.6	1.6 (–0.3-4.6)	0.20
Acetabular abduction angle <55° (% of patients)	97	93	3.9 (–10.5-10.8)	0.99

^*Postoperative anteroposterior pelvic radiographs obtained at the four-week follow-up visit were reviewed to determine the femoral and acetabular component positions. There were no significant differences between the two groups.
