Abstract
Computed tomography is used to assess whether ideal femoral component size in knee arthroplasty can be made more accurately. Ideal femoral component size was measured on radiography, computed tomography, and by direct measurement of 20 cadaver femora and analyzed statistically. There was no significance between the tomographically anticipated ideal femoral component size and ideal femoral size values (Wilcoxon W 388.5; p 0.565). There was difference between radiographically anticipated ideal femoral size and ideal femoral size values (Wilcoxon W 324.5; p 0.020). Anticipating the ideal femoral size can be made more precisely with computed tomography than radiographs in cadaver femora. Anticipating the ideal femoral component size by computed tomography may solve the problems in "in-between sizes." Future total knee designs may be manufactured in more anatomic sizes.
计算机断层扫描用于评估膝关节置换术中理想股骨假体大小是否可以更准确地确定。通过x线摄影、计算机断层扫描和直接测量20具尸体股骨测量理想股骨成分大小，并进行统计分析。断层扫描预测的理想股骨假体尺寸与理想股骨尺寸值之间没有显著性差异(Wilcoxon W 388.5;p 0.565)。x线片预期的理想股骨尺寸与理想股骨尺寸值之间存在差异(Wilcoxon W 324.5;p 0.020)。在尸体股骨中，计算机断层扫描比x线摄影能更精确地预测理想的股骨尺寸。通过计算机断层扫描预测理想的股骨假体尺寸可以解决“中间尺寸”的问题。未来的全膝关节设计可能会有更大的解剖尺寸。
