The knee is a vital joint in the human body that connects the thigh to the lower leg. It allows for movement, enabling us to walk, run, and jump. The knee is made up of bones, cartilage, ligaments, and tendons, all working together to provide stability and flexibility. Injuries to the knee, such as sprains or tears, can be quite common, especially in sports. Proper care, including rest and physical therapy, is essential for recovery. Keeping the knee strong through exercises can help prevent injuries and maintain mobility as we age.
