KNEE ANTERIOR CRUCIATE LIGAMENT ANATOMY
Knee Anterior Cruciate Ligament Anatomy legal movies
The anterior cruciate ligament runs upwards and backwards from its tibial origin near the front of the tibial plateau, to its attachment at the posterolateral part of the intercondylar notch of the femur. The anterior cruciate ligament prevents forward movement of the tibia in relation to the femur, and with the posterior cruciate ligament, stabilizes the knee in the anteroposterior direction and allows the joint to work as a hinge while keeping the articular surfaces in contact.

The two cruciate ligaments, along with other ligaments and muscles, cause the rolling â€“ sliding movements of knee flexion and extension. The anterior cruciate ligament consists of closely attached ligament bundles, which spiral around each other ninety degrees. They are each taut and supportive during different knee positions.

The cruciate ligaments lie in the centre of the joint, largely within the intercondylar notch.
The anterior cruciate ligament is attached to the anterior intercondylar fossa of the tibia, along the edge of the medial condyle and between the insertion of the anterior horn of the medial meniscus anteriorly and that of the lateral meniscus posteriorly. It runs obliquely superiorly and laterally and is attached above to a narrow patch on the internal aspect of the lateral condyle of the femur which extends vertically above and along the edge of the articular cartilage. The ligament has a more anterior attachment to the tibia and a more lateral attachment to the femur than its fellow.
Behind the anterior cruciate ligament is the posterior cruciate ligament. It is attached to the posterior part of the posterior intercondylar fossa of the tibia, overlapping the posterior rim of the upper surface of the tibia. Its tibial insertionis placed well posterior to the insertion of the posterior horns of the lateral and ...
