Abstract

The repair and reconstruction of bone defects are still major problems to be solved in the field of orthopedics. Meanwhile, 3D-bioprinted active bone implants may provide a new and effective solution. In this case, we used bioink prepared from the patient’s autologous platelet-rich plasma (PRP) combined with polycaprolactone/β-tricalcium phosphate (PCL/β-TCP) composite scaffold material to print personalized PCL/β-TCP/ PRP active scaffolds layer by layer through 3D bioprinting technology. The scaffold was then applied in the patient to repair and reconstruct bone defect after tibial tumor resection. Compared with traditional bone implant materials, 3D-bioprinted personalized active bone will have significant clinical application prospects due to its advantages of biological activity, osteoinductivity, and personalized design.
