Total knee arthroplasty in patients with Ranawat type-II valgus arthritic knee with a marked coronal femoral bowing deformity: comparison between computer-assisted surgery and intra-articular resection

Table 4 Comparison of percentage of postoperative lower limb alignment (within 3° deviation) and component alignment

Parameters	CAS-TKA	Bone-Resect-TKA	P value
Parameters	n = 22	n = 28	P value
Mechanical axis within 3° deviation
	20 (90.9 %)	18 (64.3 %)	0.029*
Component positioning
Femoral valgus angle	20 (90.9 %)	18 (64.3 %)	0.029*
Femoral flexion angle	19 (86.4 %)	17 (60.7 %)	0.044*
Tibial valgus angle	22 (100 %)	26 (92.9 %)	0.309
Tibial flexion angle	20 (90.9 %)	25 (89.3 %)	0.616

Data are n (%). P for between-group comparisons was determined using χ ² tests
CAS-TKA knees treated with computer-assisted surgery—total knee arthroplasty, Bone-Resect-TKA knees treated with intra-articular bone resection—total knee arthroplasty
