Preclinical Feasibility of the Bio-Airbrush for Arthroscopic Cell-Based Cartilage Repair.

This study shows that a bio-airbrush can be a clinically feasible instrument for the use in cell transplantations to repair knee cartilage defects. This technology would enable a shift from cartilage repair procedures, which are mostly performed using an arthrotomy, toward a fully arthoscopic approach. In addition, the technology presented could possibly be translated to other fields of research where controlled deposition of cells is required, such as treatment of burn wounds/ulcers/others.
