cruciate ligaments

two intracapsular ligaments of the knee, forming an X-shape, linking the femur to the tibia, strong but not elastic, which are crucial for the stability of the knee joint. The anterior cruciate ligament runs upwards, backwards and laterally from the front of the upper end of the tibia to attach to the medial aspect of the lateral femoral condyle; it limits forward movement of the tibia relative to the femur and tightens with extension at the knee. It is short and thick with a poor blood supply. The posterior cruciate ligament arises from the posterior intercondylar area of the tibia and runs forwards, upwards and medially to attach to the anterolateral surface of the medial femoral condyle. It limits backwards movement of the tibia relative to the femur and tightens with flexion at the knee. cruciate ligament injury (especially anterior) can result in a rapid accumulation of blood in the knee joint (haemarthrosis) and is often associated with damage to other structures, especially the medial meniscus. Treatment depends on the sport involved, the degree of instability and of other damage. In sportspeople complete rupture usually requires surgical repair, resulting in a lengthy (up to 9 months) rehabilitation programme, before return to sport. Disruption of only the posterior ligament may result in significant instability but may be hard to diagnose clinically. See also drawer sign, Lachman test.
