Abstract:

BACKGROUND: Articular cartilage repair has been a difficulty in the clinical setting, which is mainly treated with autologous or allogeneic osteochondral grafts, and cartilage periosteum or periosteum grafts. However, the limited source, secondary lesion and immunological rejection force some researchers to search for a novel treatment strategy, cartilage tissue engineering, that is of great significance for cartilage regeneration and repair.
OBJECTIVE: To investigate the tissue-engineered scaffolds for the repair of articular cartilage defects.
METHODS: The first author searched the PubMed and WanFang databases for the articles addressing tissue-engineered cartilage for articular cartilage defects published between 1991 and 2015 using the keywords “articular cartilage defect, scaffold, tissue engineered cartilage” in English and Chinese, respectively. The irrelative and repetitive literatures were excluded.
RESULTS AND CONCLUSION: Finally 48 eligible literatures were enrolled based on the inclusion and exclusion criteria. Cartilage tissue engineering possesses the advantages of controllability, little damage to tissue itself, and biological repair of injured cartilage. Tissue-engineered scaffold material is a critical factor in tissue engineering construction; therefore, it should hold biodegradability and histocompatibility. The commonly used scaffold materials include natural macromolecule materials (collagen, silk fibroin and chitosan), and synthetic polymer materials (polylactic acid and tricalcium phosphate). It is necessary to prepare composite scaffolds with high bioactivity integrate advantages of each material. The tissue engineering is bound to be a hotspot in the field of articular cartilage repair.
