Navigation-guided transfer of cartilage defect geometry for arthroscopic autologous chondrocyte transplantation

Cartilage repair with autologous chondrocyte transplantation shows intriguing results. Chondrogenic transplants generally must be inserted into cartilage defects via arthrotomy. The following study showed that arthroscopically-guided navigation could detect and precisely measure the cartilage defect sizes of different geometries. The new cartilage defect-managing module allowed for the precise transfer of navigated cartilage defect geometries for exact size preparation of the tissue engineering scaffolds. Therefore, navigation can help accomplish chondrocyte transplantation arthroscopically.
