Table 3 Comparison of percentage of postoperative lower limb axis (within 3° deviation) and component positioning between the conventional and CN-TKA groups

From: Comparison of computer-navigated and conventional total knee arthroplasty in patients with Ranawat type-II valgus deformity: medium-term clinical and radiological results

  No. of postoperative component positioning within 3°deviation
  Group A Group B p-value
  N = 36 N = 34  
Mechanical axis within 3° deviation 30 (83.3%) 32 (94.1%) 0.267
Component positioning
Femoral valgus angle 35 (97.2%) 34 (100%) 1.000
Femoral flexion angle 20 (55.6%) 26 (76.5%) 0.136
Tibial valgus angle 36 (100%) 34 (100%) -
Tibial flexion angle 33 (91.7%) 31 (91.2%) 1.000
  1. Group A: Knees undergoing conventional TKA.
  2. Group B: Knees undergoing CN-TKA.
  3. The values are given as the n (%).
  4. P values for between-group comparison were determined by chi-square tests.
  5. *Statistically significant (p value <0.05).
