Method for manufacturing an implantable bone augment arranged to at least partially fit in a bone defect in a bone of a patient, wherein the method comprises the steps of: - providing a three-dimensional model of at least a part of the bone of the patient comprising the bone defect； - designing the shape and size of an augment based on the three-dimensional model, wherein a bone contacting surface of the augment is formed complementary to a corresponding outer surface of the bone, in particular a surface of the bone defect； - designing the body of the augment having the designed shape and size and having a porous microstructure, wherein the step of designing further comprises providing reinforcements in said body based on predicted loading conditions of the implanted augment, and； - manufacturing the designed augment.
