"Outliers" in osteoarthritic knees concerning distal femoral valgus angle and femoral rotation angle reply

Abstract

Weread with interest the article in press at your journal entitled “Variability in distal femoral anatomy in patients undergoing total knee arthroplasty: measurements on 13,546 computed tomography scans” written byMeric et al [1].We congratulate them for their inspiring work. The authors analyzed 13,546 computed tomographic (CT) scans of arthritic patients undergoing total knee arthroplasty (TKA) and measured distal femoral valgus angle (DFVA) between the anatomic and mechanical axis, and femoral rotation angle (FRA) relative to posterior condylar line.
