[Articular cartilage regeneration using scaffold]

Abstract

The self-healing capacity of articular cartilage for repair is limited. For articular cartilage injury, several surgical techniques are used in clinical practice, namely drilling, abrasion arthroplasty, microfracture, or autologous osteochondral grafting, while various methods of autologous chondrocyte transplantation to cartilage defect sites have been reported since 1990s. In a case of chondrocyte transplantation to cartilage defect site, the use of proper scaffold is important. Currently, collagen gel or PLGA is used widely as a scaffold.
