Microfracture is a technique used for full thickness cartilage defects. Articular cartilage has a limited capacity to regenerate itself due to its lack of blood supply. Micro-fracture was designed to stimulate a biologic repair of fibrocartilage. This fibrocartilage is not as strong as native articular cartilage. A minimally invasive arthroscopic technique is used to place micro-fracture holes into the exposed bone at the base of a cartilage defect. This allows the release of blood and bone marrow contents into the cartilage defect, activating a healing response.
