Improved femoral component rotation in advanced genu valgum deformity using computer-assisted measured resection total knee arthroplasty

Table 5 Comparison of postoperative lower limb axes of patients with genu varum (within 3° deviation) and component positioning

	Postoperative positioning within 3° deviation
	Group A	Group B	p value
	n = 39 (%)	n = 51 (%)	p value
Coronal mechanical axis within 3° deviation	36 (92.3)	42 (82.3)	0.220
Component positioning
Frontal femoral angle	35 (89.7)	42 (82.3)	0.378
Femoral rotation angle	36 (92.3)	46 (90.2)	0.730
Frontal tibial angle	39 (100)	49 (96.1)	0.501
Sagittal tibial angle	37 (94.8)	49 (96.1)	1.000

Group A: osteoarthritis with genu varum and underwent computer-assisted surgery total knee arthroplasty (CAS-TKA)
Group B: osteoarthritis with genu varum and underwent conventional TKA
Data are presented as number (%)
p values for between-group comparison were determined by chi-square tests
