The Use of Scaffolds in Cartilage Regeneration.

Scaffolds are important tools in tissue engineering and play a unique role in tissue regeneration and repair of damaged tissues. A variety of natural, synthetic, and composite scaffold types can be used in cartilage tissue engineering. The limited capability of cartilage to repair itself has always been a problem during recovery from damage. The success of cartilage regeneration is dependent on a couple of factors, but the basic properties of scaffolds are biocompatibility, degradability under physiological conditions, and structural support for cell attachment. In this review, we summarize the use of different scaffold types in cartilage regeneration.
