  1. Group A: Knees undergoing conventional TKA.
  2. Group B: Knees undergoing CN-TKA.
  3. IKS Score = International Knee Society Score.
  4. The values are given as the mean with the range in parentheses.
  5. P values for between-group comparison were determined by t tests.
  6. *Statistically significant (p value <0.05).
