  • Collagen carrier of therapeutic genetic material, and method
    Publication number: 20030039695
    Abstract: A collagen matrix material is charged with a cell growth-promoting derived nucleic acid sequence. The nucleic acid sequence-charged collagen matrix material may be utilized in a method of promoting regeneration of surface cartilage of a joint. In the method, an area of injury is covered with the nucleic acid sequence-charged collagen matrix material, the collagen matrix material is fixed over the area to be treated, and the area is allowed to heal.

  • Method for promoting regeneration of surface cartilage in a damage joint
    Patent number: 6352558
    Abstract: A method of promoting regeneration of surface cartilage of a joint includes the steps of forming punctures in a subchondral plate of an area of the joint to be treated, covering the puncture and the area to be treated with a chondrocyte-free patch made of a sheet of collagen membrane material without adding chondrocytes to the area to be treated, fixing the patch over the area to be treated, and allowing the area to be treated to regenerate cartilage without adding chondrocytes to the area to be treated.
