Cartilage damage refers to the deterioration or injury of the cartilage tissue in joints, particularly in areas such as the knees, shoulders, and hips. Cartilage is a smooth, rubber-like tissue that covers the ends of bones and acts as a cushion to prevent friction and absorb shock during movement. When cartilage is damaged, it can lead to pain, inflammation, stiffness, and reduced joint function. Common causes of cartilage damage include aging, overuse, sports injuries, and medical conditions like osteoarthritis. Treatment options for cartilage damage may include physical therapy, medications, injections, and in severe cases, surgery such as cartilage repair or replacement procedures. Researchers are constantly studying ways to improve the understanding and treatment of cartilage damage to help improve the quality of life for individuals suffering from joint pain and immobility.
