Description

technical field

[0001] The invention relates to a preparation method and application of a tissue engineering compound, in particular to a preparation method and application of a tissue engineering osteochondral compound. Background technique

[0002] The injury and defect of articular cartilage is a common disease in clinical orthopedics. Connection replacement and osteochondral defect reconstruction are very important for restoring bone and cartilage function. At present, non-biological substitutes, xenogeneic and allogenic osteochondral transplantation are usually used clinically. for the treatment of cartilage defects. However, the connection replacement effect of non-biological substitutes is not long-lasting, and often wears and loosens; the availability of autologous donor tissue and the damage of the donor limit the application of autologous transplantation, and there are risks such as immune rejection and viral infection in allogeneic transplantation , cannot achiev...
