★ Osseous Injuries in ACL Tears with Pivot Shift Injury
Osseous injuries typically affect the anterior/central aspect of the lateral femoral condyle and the posterior aspect of the lateral tibial plateau. Although less common, the posterior aspect of the medial tibial plateau and medial femoral condyle may also exhibit contusive injuries.
✅ Deep Notch Sign:
This sign is defined by an abnormal deepening of the condylofemoral sulcus by more than 1.5 mm (or 2 mm). It suggests an osteochondral fracture in the lateral femoral condyle.
✅ Long Notch Sign:
Abnormal elongation of the condylofemoral sulcus characterizes this sign. Like the deep notch sign, it indicates an osteochondral fracture in the lateral femoral condyle.
