Table 3. Comparison of Radiographic Outliers between Robotic and Conventional Total Knee Arthroplasty Groups.

Variable	Robotic group (n = 69)	Conventional group (n = 39)	p-value
Mechanical axis (θ)	6	13	< 0.001
Coronal femoral inclination (α)	4	12	< 0.001
Coronal tibial inclination (β)	1	4	0.03
Sagittal femoral inclination (γ)	10	23	< 0.001
Sagittal tibial inclination (δ)	6	17	< 0.001

Chi-square test or Fisher exact test. The p-values are of intergroup comparisons, with p < 0.05 indicating significance.
