Abstract: Articular cartilage injury is common in clinical in recent years, due to the trauma or bone disease. There are many methods for the repair of articular cartilage injury currently, but each has its limitations. With the development of nanotechnology and bionic-technology, the scaffold plays an important role with tissue engineering technique in the repair of articular cartilage injury, in which the composite materials are the hot direction of the research and development, the full application of nanotechnology and bionic-technology prospect in the future.
