3D printed constructs for osteochondral defect repair (MultiBio-Ink)

Background

Osteochondral defects are still a major clinical challenge. They represent a large societal burden as they limit employment and impede daily life activities of millions of Europeans. Moreover, these injuries often lead to further degeneration of the joint, into a disabling disease known as osteoarthritis (OA). The defect bridges two major tissue types (cartilage and bone) that also have zonal structures within and specific healing capacities. Additionally, the cartilaginous surface must follow the patient specific contour of the surrounding tissue to avoid arthritic changes. In this project we bring together expertise in biomaterials and bioprinting to develop an additive manufacturing approach to produce constructs with precisely controlled internal architecture and the potential for patient specific implants. We are systematically investigating how to create collagen fibrils with controlled orientation within a hyaluronic acid-based matrix, thereby imitating the natural tissue composition. The possibility of printing matrix components with control over microscopic alignment brings biofabrication one step closer to capturing the complexity in animal tissues, opening new possibilities for clinical translation.
