At present, strong requirements in orthopaedics are still to be met, both in bone and joint substitution and in the repair and regeneration of bone defects. In this framework, tremendous advances in the biomaterials field have been made in the last 50 years where materials intended for biomedical purposes have evolved through three different generations, namely first generation (bioinert materials), second generation (bioactive and biodegradable materials) and third generation (materials designed to stimulate specific responses at the molecular level). In this review, the evolution of different metals, ceramics and polymers most commonly used in orthopaedic applications is discussed, as well as the different approaches used to fulfil the challenges faced by this medical field.

Koch, M. A., Engel, E., Planell, J. A., Lacroix, D., (2008). Cell seeding and characterisation of PLA/glass composite scaffolds for bone tissue engineering Journal of Biomechanics 16th Congress, European Society of Biomechanics , Elsevier (Lucerne, Switzerland) 41, (Supplement 1), S162

In this study polymer-glass composite scaffolds were characterized by permeability and porosity, two important properties for the use in perfusion bioreactors. These scaffolds were seeded with osteoblast-like cells to assess the efficiency of the used bioreactor. The used PLA/glass composite scaffolds are adequate for the perfusion culture. The high porosity and pore interconnectivity allow an even cell distribution and incorporation of a high cell number. For optimisation of the perfusion bioreactor system, further research has to be dedicated to the cell seeding and culture.
