A
Posterior cruciate ligament (PCL) tear
B
Medial collateral ligament (MCL) tear
C
Anterior cruciate ligament (ACL) tear
D
Lateral collateral ligament (LCL) tear
Explanation:The correct option is 'c'. A Segond fracture is an avulsion fracture of the lateral capsule and the anterolateral ligament (ALL) from the lateral tibial plateau. It occurs with internal rotation and varus stress. On an AP radiograph, it appears as an elliptical bone fragment lateral to the tibial plateau and has a 75-100% association with an underlying anterior cruciate ligament (ACL) tear.
