description	The invention relates to a knee joint defect cushion block and a manufacture method therefor. The method comprises the following steps: obtaining a tibia model, and exporting the tibia model into Magics software; rebuilding a knee joint prosthesis model and exporting the knee joint prosthesis model into the Magics software; completing matching of the tibia model and the knee joint prosthesis model, fabricating a medial bone defect of a tibia plateau, completing implantation of a cushion block and conducting meshing; applying working conditions and constraints on an overall model which is constituted of the heterogeneous tibia model and the knee joint prosthesis model in Hypermesh software and conducting finite element analysis; and carrying out topological optimization analysis, wherein ifthe optimized gradient-meshed cushion block satisfies preset changing indexes, additive manufacturing is carried out to obtain the knee joint defect cushion block. The knee joint defect cushion blockhas a mesh architecture a
