Abstract:

BACKGROUND: In recent years, the research about three-dimensional digital models of anterior cruciate ligament has been developed rapidly in abroad. However, there is no basic anatomy report about three-dimensional digital models of the knee joint and anterior cruciate ligament at home.
OBJECTIVE: To explore the validity and reliability of two-dimensional MRI image and MIMICS software in building three-dimensional digital models of the knee joint and anterior cruciate ligament.
METHODS: Twenty fresh normal adult corpse knee-joint specimens were selected, then they were scanned with MRI, acquired continuous image data of level thick 1.0 mm, and these data were imported into computer with DICOM form and were carried through three-dimensional reconstruction by using MIMICS software. The three-dimensional substance digital models of double knee joints which included femur distal end, tibia proximalis, anterior cruciate ligament, meniscus, patella and fibula were reconstructed. Measurement software was utilized for relevant indexes. Meanwhile, the corpse specimens were dissected to measure relevant data of the anterior cruciate ligament, and the difference of measured indexes between the corpse specimen and the three-dimensional substance model was analyzed.
RESULTS AND CONCLUION: There was no difference between the data of corpse specimen and three-dimensional substance digital model (P > 0.05). It indicated that MRI image data of the human knee joint and anterior cruciate ligament could be used to reconstruct the authentic and reliable three-dimensional digital models of the knee joint and anterior cruciate ligament.
