A preliminary report of fast establishment of three-dimensional digital models of anterior cruciate ligament based on MRI
Objective To investigate the method of quickly establishing three-dimensional digital model of anterior cruciate ligament (ACL) using magnetic resonance imaging (MRI), and to evaluate authenticity and reliability of the model. Methods Contralateral knee joint MRI data of 20 cases of patients with clinical diagnosis of ACL rupture were selected. These data were imported into independent development of 3D-MIA software, and were segmented by the method of independent invention of ACL fast segmentation technology, and then three-dimensional substance digital models of ACL and the knee joint were established by carrying through three-dimensional reconstruction on the basis of surface rendering. The length, width, thickness, and the angle of ACL and the human body planes were measured on models. The results were compared with that of early anatomical results. Results Three-dimensional digital models included bones and cruciate ligaments of the knee joint . The average building time was 18 minutes. The mean length, width and thickness of ACL were (39.80±1.86), (5.80±1.83) and (9.96±1.26) mm respectively, and the angle formed by ACL and the coronal plane, sagittal plane, horizontal plane were (27.58±3.64)°, (39.82±4.01)° and (22.27±4.23)° respectively. Compared with the corresponding data of previous researches, by independent sample t-test, there was no significant difference (P>0.05). Conclusions A relatively reliable three-dimensional digital model of ACL and the knee joint can be quickly established using the novel ACL segmentation technology and 3D-MIA software, laying an foundation for establishing a complete set of computer aided ACL operation system and realizing the dream of simulational, individualized and anatomical reconstruction of ACL in the future.
