This 2014 comprehensive review examines the design principles for biomimetic porous scaffolds intended to replace or augment bone in orthopedic reconstruction. It asks: what structural, mechanical, surface, and biodegradation properties must a synthetic scaffold possess to functionally replicate native bone and integrate with host tissue?
When evaluating commercially available bone graft substitutes or metallic implants, the modulus mismatch between dense metal (stainless steel ~193 GPa, Ti6Al4V ~110 GPa) and cortical bone (7–18.9 GPa) explains stress-shielding and periprosthetic bone loss — understanding this drives the rationale for porous metals, low-modulus titanium alloys, and HA-coated surfaces in modern implant design.
When selecting scaffold materials for different defect contexts, remember that pore size, porosity percentage, and surface chemistry are independent levers that each influence both mechanical integrity and the biologic response.
