Cartilage repair is a medical procedure aimed at restoring damaged cartilage, a flexible tissue that cushions joints. This type of tissue does not heal easily due to its limited blood supply. Various techniques, such as microfracture, autologous chondrocyte implantation, and osteochondral grafting, are used to promote healing and regrowth. Successful cartilage repair can alleviate pain, improve joint function, and enhance the quality of life for individuals with conditions like osteoarthritis or sports injuries. Ongoing research continues to explore new methods and materials to improve the effectiveness of cartilage repair treatments.
