Bionic gradient knee femoral prosthetic structure and manufacturing method

The present invention discloses a femoral knee prosthesis gradient bionic structure and its manufacturing method prosthesis structure comprising a smooth surface on the distal femur housing native form, osteotomy full coverage of the bonding surface, and a fixed gradient porous structure means full coverage osteotomy reverse surface bonded to the distal femur stretched to native surface, instead of the distance to the surface at a thickness of more than 5mm entity with a gradient porous structure, fixing means to generate a plane on the inside of the distal femoral prosthesis. The present invention is normalized with respect to the conventional high adapted prosthesis, knee prosthesis and bone morphogenetic native consistent high, more suitable for patient motion. Bionic gradient of the present invention is easy to manufacture a knee joint femoral prosthesis, the conventional manufacturing methods conventional bionic prostheses gradient structure is very difficult, 3D printing, the production method of the present invention can be realized using individual differences according to the patient custom prostheses, short production period, low cost, provides the possibility for the application and development of individual adaptation of treatment.
