The chondrocycles can be harvested, cultured in the laboratory for about 3 weeks and implanted into the chondral defect site. Hyaline cartilage was found in the repaired tissue. However, the complicated laboratory procedures made the clinical application far from easy. In collaboration with the researchers from the Industrial Technology Research Institute, we have developed the biphasic matrix to host the chondrocytes that were obtained from enzymatic digestion of the chopped articular cartilage harvested from the nonweight bearing site of the joint. From series of per-clinical animal experiments, the osteochondral defects could be repaired. This new technology has several advantages: 1.No need for laboratory manuals to acquire chondrocytes. 2. The procedure could be done through arthroscopic procedure in one stage operation in about 30 minutes. 3. The procedure is easy to learn. This technology was transferred to the Exactech in March 2008. A Multi-center clinical trial is ongoing in Taiwan. We anticipate to obtain the license to market the biphasic matrix in Taiwan in the coming years. • Jiang CC, Chiang H, Liao CJ , Lin YJ , Kuo TF, Shieh CS, Huang YY, Tuan TS.
