^aIf the alignment between femoral and tibial component was in flexion, degrees were assigned positive values, whereas if the alignment was in extension, degrees were assigned negative values; *Statistical significance was observed compared with conventional technique with ANOVA (p < 0.01); CFA = conventional femoral axis; CTA = conventional tibial axis; NFA = navigation femoral axis; NTA = navigational tibial axis; SMA = sagittal mechanical axis.
