Kits and compositions are provided for the treatment and repair of defects in the cartilage or bone of humans and other animals as in full-thickness defects in joints. A matrix having pores large enough to allow cells to populate the matrix and to form blood vessels is used to fill the defect in bone. The matrix filling the bone defect contains an angiogenic factor and also contains an osteogenic factor in an appropriate delivery system. A matrix having pores sufficiently large to allow cartilage repair cells to populate the matrix is used to fill a defect in cartilage to induce cartilage formation. The matrix filling the defect in cartilage contains a proliferation agent and also contains a transforming factor in an appropriate delivery system. The matrix may also contain a chemotactic agent to attract cartilage repair cells. In a full-thickness defect, a membrane is used to separate the defect sites in bone and cartilage, which is sealed to the cartilage-bone-junction and which prevents blood vessels and associated cells from penetrating from one site to the other. |
