  1. 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. The values are given as the n (%); p values for between-group comparison were determined by chi squared tests.
  2. *Statistically significant (p value < 0.05).
