Tissue Engineered Cartilage Repair Using Small-Incision Implantation of Decalcified Corticocancellous Bone Scaffold

Abstract

Treatment of cartilage injuries is a prominent topic internationally. Recently, tissue engineering has been used to repair cartilage injury. In China, several scaffolds have been approved for clinical trials aimed at cartilage repairing. The successful implantation of scaffold in cartilage defect areas is crucial for effective treatment. The procedure is crucial in ensuring that the scaffold is implanted successfully, which is fundamental for a good prognosis. International reports on tissue-engineered scaffold implantation technologies highlight both advantages and disadvantages. Because of limitations in the required equipment and materials, some of the surgical techniques used internationally are not applicable in China. To optimize the technology of tissue-engineered scaffolds for cartilage repair in China, this Technical Note discusses the implantation techniques and skills involved, focusing on small-incision implantation of decalcified cortex-cancellous bone scaffolds. This work contributes to standardizing the surgical procedures for tissue engineering scaffold technology in repairing cartilage injuries.
