Abstract:

BACKGROUND: How to design and manufacture sophisticated artificial knee joint that meets the needs of patients after knee joint replacement rely on the precise design and manufacturing technology, which ensure the prosthesis match the body and make a coordinated movement with maintained soft tissues. 
OBJECTIVE: To design personalized knee joint utilize of computer-aided design technology.
METHODS: The human knee joint was scanned by three-dimensional laser scanning and output of the point cloud data were processed by computer-aided design technology. After that, the three-dimensional solid model of the knee was reconstructed by Geomagic and UG software.
RESULTS AND CONCLUSION: A very precise three-dimensional knee model was constructed. It provides an accurate model basis for the digital manufacture of biomimetic artificial knee, virtual assembly, stress analysis, motion analysis, and surgical simulation.
