Abstract:
Background: In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment ofthe femoral component in total knee arthroplasty (TKA).Methods: There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittalfemoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cortical line(DACL) were measured. Finally, the correlation of component alignment and SFB was examined.Results: Mean SFB was 7±2.7 degrees. The component was in flexion position in relation to mechanical axis and DACL as8.4±2.9 degrees and 1.7±0.9 degrees, respectively. The flexion alignment of the component was significantly correlatedwith SFB.Conclusion: Mechanical alignment of the limb in both coronal and sagittal axes should be preserved in TKA. SFB cansignificantly increased the flexion alignment of the femoral component.
