Injuries around the knee

The knee is the largest joint in the body, and one of the most easily injured. Your knee is a complex joint with many components, making it vulnerable to a variety of injuries. Many knee injuries can be successfully treated with simple procedures, such as bracing and rehabilitation exercises. Other injuries may require surgery to correct. It is made up of four main things: bones, cartilage, ligaments, and tendons.

  • Bones. Three bones meet to form your knee joint: your thighbone (femur), shinbone (tibia), and kneecap (patella).
  • Articular cartilage. The ends of the femur and tibia, and the back of the patella are enclosed with articular cartilage. This slippery substance helps your knee bones glide smoothly across each other as you bend or straighten your leg.
  • Ligaments. Bones are connected to other bones by ligaments. The four main ligaments in your knee act like strong ropes to hold the bones together and keep your knee stable.
  • Tendons. Muscles are connected to bones by tendons. The quadriceps tendon connects the muscles in the front of your thigh to your patella. Stretching from your patella to your shinbone is the patellar tendon.
