The invention relates to an individualized design and manufacturing 
system and an individualized design and manufacturing method for a full 
knee joint replacing 
prosthesis. Through three work stations set in different places, doctors, design personnel and 
engineering personnel are connected, in addition, the 
image processing technology, the virtual 
operation planning, the information communication, the individualized 
interaction design, the product performance fast analysis and the 3D (three-dimensional) printing 
manufacturing technology are merged, through the 
system, the doctors can know the design and manufacturing conditions of the 
knee joint prosthesis at any time, the design personnel can design the personnel applicable 
prosthesis according to the 
knee joint form of a patient and can modify the 
prosthesis design at any time according to the scheme of the doctors, finally, the 
engineering personnel use the 3D printing technology for manufacturing the designed prosthesis, and the individualized knee 
joint prosthesis best matched with the knee joint of the patient is produced, so the optimum matching between the prosthesis and the knee joint is ensured on the basis of minimum 
bone cutting quantity, and the effect optimization is realized. The 
system and the method have the advantages that the trouble that the existing prosthesis product cannot be better matched with the 
knee joint structure can be avoided, in addition, the individualized and customized replacing operation scheme for the patient becomes possible, and great significance is realized in the medical field.
