Toward clinical application of tissue-engineered cartilage.

Since the late 1960s, surgeons and scientists envisioned use of tissue engineering to provide an alternative treatment for tissue and organ damage by combining biological and synthetic components in such a way that a long-lasting repair was established. In addition to the treatment, the patient would also benefit from reduced donor site morbidity and operation time as compared with the standard procedures. Tremendous efforts in basic research have been done since the late 1960s to better understand chondrocyte biology and cartilage maturation and to fulfill the growing need for tissue-engineered cartilage in reconstructive, trauma, and orthopedic surgery.
