Figure 3 Osteochondral injury lateral femoral condyle.
Lateral radiographs of two patients with complete anterior cruciate ligament (ACL) tear. A: Deep notch sign is abnormal deepening of the condylofemoral sulcus larger than 1.5 mm (white arrow); B: Long notch sign is abnormal lengthening of the condylofemoral sulcus (black straight line). These two signs are suggestive of osteochondral fracture of the lateral femoral condyle and highly associated with ACL tear though these are not very common findings.
