Group A: osteoarthritis with marked coronal femoral bowing; all underwent CAS-TKA. Group B: osteoarthritis with marked coronal femoral bowing; all underwent conventional TKA. Group C: osteoarthritis without marked coronal femoral bowing; all underwent conventional TKA. Values are shown as mean ± SD; p values for between-group comparison were determined by One-way ANOVA tests.
