Porous structures already have a wide range of applications in almost every modern sector of science, from catalysis to structural applications. Due to the possibility to easily tailor porosity and mechanical properties, porous structures also found application in the orthopaedic field, in particular to improve osteointegration properties of implants.
Different techniques were developed or adapted to obtain a good combination of mechanical strength, pore dimensions and Young’s modulus, without neglecting biocompatibility and corrosion resistance. The aim of this work is to summarise and compare the most important characteristics of the technologies currently used for the production of commercial orthopaedic porous structures.
