Abstract
In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment of the femoral component in total knee arthroplasty (TKA). There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittal femoral 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. Mean SFB was 7±2.7 degrees. The component was in flexion position in relation to mechanical axis and DACL as 8.4±2.9 degrees and 1.7±0.9 degrees, respectively. The flexion alignment of the component was significantly correlated with SFB. Mechanical alignment of the limb in both coronal and sagittal axes should be preserved in TKA. SFB can significantly increased the flexion alignment of the femoral component.
摘要
在本研究中，我们调查了股骨干矢状面弯曲如何影响全膝关节置换术（TKA）中股骨假体的矢状面排列。共有25例患者接受了TKA手术。进行了下肢侧位X线摄影。测量了股骨干矢状面弯曲（SFB）以及假体相对于矢状面机械轴和远端前皮质线（DACL）的排列情况。最后，检查了假体排列与SFB之间的相关性。平均SFB为7±2.7度。假体相对于机械轴和DACL的屈曲位置分别为8.4±2.9度和1.7±0.9度。假体的屈曲排列与SFB显著相关。在TKA中应保留肢体在冠状面和矢状面的机械排列。SFB可显著增加股骨假体的屈曲排列。
