A joint part (1) has a porous portion (2) that is defined by a multiplicity of solid regions where material is present and a remaining multiplicity of pore regions where material is absent, the locations of at least most of the multiplicity of solid regions being defined by one or more mathematical functions. The nature of the porous portion can be varied systematically by changing one or more constants in the mathematical functions and the part is made by a process of solid freeform fabrication.
