Clinical Information
  • Cartilage is the tough but flexible tissue that covers the ends of your bones at a joint. It also gives shape and support to other parts of your body, such as your ears, nose and windpipe. Healthy cartilage helps you move by allowing your bones to glide over each other. It also protects bones by preventing them from rubbing against each other. Injured, inflamed or damaged cartilage can cause symptoms such as pain and limited movement. It can also lead to joint damage and deformity. Causes of cartilage problems include
    • tears and injuries, such as sports injuries
    • genetic factors
    • other disorders, such as some types of arthritis
    osteoarthritis results from breakdown of cartilage. nih: national institute of arthritis and musculoskeletal and skin diseases
  • Condition in which there is a deviation from or interruption of the normal structure or function of cartilage, the non-vascular form of connective tissue composed of chondrocytes embedded in a matrix of type ii collagen and chondroitin sulfate.
  • Pathological processes involving the chondral tissue (cartilage).
