Erratum
After publication of the original article [1] it came to our attention that there were errors in Table 3. The data in the first parameter [preoperative coronal MA(°)] was incorrect and has been corrected in Table 3 below.
Table 3.
Radiographic data of patients with genu varum
| Group A | Group B | ||
|---|---|---|---|
| n = 39 | n = 51 | ||

| Frontal femoral angle (°) | 90.6 ± 1.7 (86–91) | 89.7 ± 1.5 (84–91) | 0.414 |
| Sagittal femoral angle (°) | 1.6 ± 1.2 (0–6) | 3.5 ± 2.8 (1–7) | <0.001* |
| Femoral rotation angle (°) | 1.0 ± 0.7 (0–3) | 1.7 ± 1.1 (0–6) | 0.127 |
| Frontal tibial angle (°) | 90.0 ± 0.5 (89–91) | 89.9 ± 1.4 (88–91) | 0.714 |

Group A: osteoarthritis with genu varum and underwent computer-assisted surgery total knee arthroplasty (CAS-TKA)
Group B: osteoarthritis with genu varum and underwent conventional TKA
p values for between-group comparison were determined by Mann–Whitney U test
*Statistically significant (p < 0.05)
