    • 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 covered with articular cartilage. This slippery substance helps your knee bones glide smoothly across each other as you bend or straighten your leg.
    • Meniscus. Two wedge-shaped pieces of meniscal cartilage act as "shock absorbers" between your femur and tibia. Different from articular cartilage, the meniscus is tough and rubbery to help cushion and stabilize the joint.
    • 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.
    • Fractures. Any of the bones in or around the knee can be fractured. The most commonly broken bone in the joint is the patella or kneecap. High impact trauma, such as a fall or car accident, causes most knee fractures.
    • Anterior cruciate ligament injuries. Share on Pinterest. ACL injuries can range from grade 1 to 3 in severity. The anterior cruciate ligament (ACL) runs diagonally down the front of the knee, providing critical stability to the joint.
    • Dislocation. Dislocating the knee happens when the bones of the knee are out of their proper placement and alignment. In a knee dislocation, one or more of the bones may slip out of place.
    • Meniscal tears. When people refer to torn cartilage in the knee, they are probably talking about a meniscal tear. The menisci are two rubbery wedges of cartilage between the thighbone and shinbone.
  2. There are 4 main ligaments in each knee. Knee ligament injuries can be caused by trauma, such as a car accident. Or they can be caused by sports injuries. The anterior cruciate ligament (ACL) is one of the most common ligaments to be injured. Treatment may include medicine, muscle-strengthening exercises, a knee brace, or surgery.
