Georgetown Engineers Pectin-Based Bone Grafts to Replace Metal Implants
Georgetown University researchers have engineered a 3D‑printed bone graft that combines pectin—a food‑grade polysaccharide—with hydroxyapatite layers to mimic natural bone architecture. The pectin matrix can be printed at room temperature, creating a porous scaffold that promotes nutrient flow and cell integration while avoiding the thermal stresses of synthetic polymers. By eliminating the need for donor‑site harvesting or metal hardware, the approach aims to reduce infection risk and improve healing outcomes. The work aligns with a broader industry shift toward biodegradable, personalized orthopedic implants, exemplified by recent FDA‑cleared and EU‑approved products.
