IN SITU SYSTEM FOR INTRA-ARTICULAR CHONDRAL AND OSSEOUS TISSUE REPAIR |
摘要 |
Disclosed is a device and method which provide a surgical therapy for in situ treatment and repair of intra-articular cartilage lesions and/or defects. The device is an implantable laminate cartilage repair patch which is bio-compatible and physiologically absorbable. The cartilage repair patch has a first outer cell occlusive layer; a second outer, cell porous layer adapted to be disposed proximate a subchondral bone wound site; and a cartilagenic matrix disposed between the first and second layers. The cartilagenic matrix is a sink for diffusion of autologous stem cells and includes chemical components promoting generation of hyaline-like cartilage in the presence of the autologous stem cells. The method of the present invention provides the autologous compositions, which when used in combination with the repair patch provides a therapeutic system to regenerate replacement hyaline-like intraarticular cartilage. |
