Erratum to: Improved femoral component rotation in advanced genu valgum deformity using computer-assisted measured resection total knee arthroplasty.

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.

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
