  • knee joint
    Knee joint (right) front (joint capsule is removed, the tendon of the quadriceps muscle of thigh with patella drawn): 1 - nadkolennika articular surface of the thigh; 2 - the posterior cruciate ligament; 3 - anterior cruciate ligament; 4 - internal meniscus; 5 - transverse ligament; 6 - ligament of the knee; 7 - articular surface of the patella; 8 - external meniscus; 9 - side peroneal link.

    The knee - components-spherical joint is formed by lateral and medial myelome hips, the superior articular surface of tibia and patella. The patella (nadolinnaya Cup) incorporated in the quadriceps tendon, the continuation of which is nadolinnaya ligament (Fig). Articular surfaces of the condyles of the femur, tibia and patella covered hyaline cartilage. Joint bag knee extensive, it synovium forms inversions, mucous bags and wrinkles that contains fat tissue. Anterior bags formed the tendon of the quadriceps muscle of thigh.
    The main ligamentous apparatus of the knee joint are: side peroneal and tibial ligaments, located on the lateral surfaces of the joint, cross (front and back) and transverse ligament inside the cavity of the knee joint. Between articular surfaces of the condyles of the femur and tibia are two Crescent-shaped cartilage - internal and external meniscus.
    The basic movement of the knee - bending and straightening. In a small limits of the possible in a bent position turns Shin outside and inside.
    The blood supply of the knee joint is carried out by branches of the popliteal artery located in the popliteal fossa. Innervation is by branches of the lumbar and sacral plexus.
