Illustration of a microfracture awl featuring a 45-degree angled tip designed to penetrate the subchondral bone during cartilage repair surgery. The surgical procedure is depicted sequentially, beginning with debridement to remove the deeply damaged cartilage. Subsequently, the microfracture awl is utilised to create vertical perforations 2 to 5 mm deep into the exposed bone surface, which induces upward bleeding and bone marrow exudation from the subchondral region. This process ultimately facilitates the formation of a fibrocartilage repair tissue layer on the articular surface
