Tibial baseplate for tibial component of a knee prosthesis, tibial component comprising the tibial baseplate and method for manufacturing the tibial baseplate

A method for manufacturing a tibial baseplate, comprising:

• manufacturing the tibial baseplate layer by layer by additive manufacturing;
• wherein the tibial baseplate is configured for tibial component of a knee prosthesis;
• wherein the tibial baseplate comprises:
• a bulk solid portion comprising a proximally facing surface adapted to accommodate a bearing element for the articulation of a femoral component of said knee prosthesis;
• and
• a plurality of porous portions to allow bone ingrowth, being integral with said bulk solid portion and having a porous portion contacting surface opposite to said proximally facing surface adapted to contact a proximal tibia;
• wherein said plurality of porous portions are seamlessly incorporated in said bulk solid portion, wherein said plurality of porous portions are embedded into the bulk solid portion and are separated from each other by a solid non-porous part of the bulk solid portion such that each porous portion is surrounded by solid non-porous material of the bulk solid portion except for the porous portion contact surface that is adapted to contact the proximal tibia;
• and
• wherein said plurality of porous portions are embedded into the bulk solid portion.
