ⓘ Deep lateral femoral notch sign

In radiology, the deep lateral femoral notch sign is a finding on a lateral radiograph that is considered an indirect sign of a torn anterior cruciate ligament. It is an abnormal deepening of the lateral condylopatellar sulcus from an osteochondral impaction fracture. A depth greater than 1.5 mm is a reliable sign of a torn ACL.

                                     
  • Hilgenreiner line, touching the lateral margin of the acetabular roof. This leads to four quadrants and a normal femoral head has to be located in the inferomedial
  • obliquely from the lateral femoral epicondyle down to the posterior surface of the tibia. The subpopliteal bursa is located deep to the muscle. Popliteus
  • longitudinal axis of the femoral shaft and its mechanical axis, which is a line from the center of the femoral head to the intercondylar notch of the distal femur
  • of thalamus lateral fissure lateral funiculus lateral geniculate body or nucleus lateral horn lateral hypothalamus lateral lemniscus lateral olfactory stria
  • large, isolated femoral defects in younger people. In this surgery, chondrocytes are arthroscopically extracted from the intercondylar notch of the articular
  • extend from the head of the tibia to the intercondyloid notch of the femur. The ACL is lateral and the PCL is medial. They cross each other like the limbs
