Abstract:

BACKGROUND: X-ray, CT, and MRI two-dimensional images for measurement of the intercondylar notch are limited by the projection position and selection of measurement level and the measurement accuracy is poor.
OBJECTIVE: To explore the accuracy of three-dimensional digital model based on MRI images and to compare the difference of three-dimensional digital intercondylar notch model with cadaver.
METHODS: There were 18 male cadaveric knees and 14 female cadaveric knees scanned by MRI two-dimensional images. The MRI images were imported into Mimics Software for intercondylar notch three-dimensional reconstruction, the related anatomical data which were gotten from the three-dimensional digital model named as three-dimensional reconstruction group, while the cadavers were dissected to measure anatomical data named as entity group.
RESULTS AND CONCLUSION: The measuring values had no differences between the three-dimensional reconstruction group and entity group (P > 0.05). The three-dimensional digital model based on MRI images could accurately show the entity specimens information. It could be used for anatomy research of the normal femoral intercondylar notch.
