摘要：

背景：磁共振图像三维测量法不仅能观察和测量一个方向或一个平面的膝关节径线，也可多方向测量多个平面径线和角度。 
目的：评价磁共振图像测量在临床上膝关节置换中假体旋转对线中的应用。
方法：以“磁共振，置换”为中文关键词，以“magnetic resonance imaging，replacement”为英文关键词。采用计算机检索2001-01/2009-10有关磁共振图像测量在临床上膝关节置换中假体旋转对线中应用的文章。
结果与结论：磁共振和CT同是三维测量，均能测量股骨外上髁最凸点、股骨内上髁沟最低点、股骨内上髁最凸点与膝关节后侧及远端关节线的距离，测量内上髁沟深度、宽度，并测量股骨远端内外上髁的前后径大小，以及测量股骨假体旋转角度，所测量的数据在临床上均有应用意义，且磁共振成像显示软组织远胜于CT，故磁共振图像测量可作为一种较理想的临床膝关节置换中假体旋转对线的测量方法。

Abstract:

BACKGROUND: Three-dimensional magnetic resonance image (MRI) measurement method can not only observe and measure knee diameters in one direction or a plane, but also measure the multi-directional and multi-plane diameter lines and angles.
OBJECTIVE: To assess the application of MRI measurement in the rotational alignment of knee prosthesis during knee replacement.
METHODS: A computer-based search was performed for retrieve of articles published 2001-01/2009-10 about the clinical application of MRI measurement in the rotational alignment of knee prosthesis. The key words were “magnetic resonance imaging, replacement” in Chinese and English.
RESULTS AND CONCLUSION: Both of MRI and CT are three-dimensional measurement tools, which can measure the distance of the maximal salient point of the external epicondyle of the femur, the lowest point of the medial epicondyle of the femur, the maximal salient point of the medial epicondyle of the femur from the joint line between the back of the knee and distal end of the knee, groove depth and width of the medial epicondyle, the anteroposterior diameter of the femur, and the rotation angle of knee prosthesis. All the measurement data are of clinical significance. The findings show that the role of MRI measurement is superior to CT. As a result, MRI measurement can be considered as an ideal measurement method for the rotational alignment of knee prosthesis during knee replace replacement.
