Or more pragmatically, the orthopaedic team assume that the presence of Segond fracture equals ACL rupture, as the correlation is close to 100%.

[1][2][3][4] The long-term benefit of an associated Anterolateral Ligament (ALL) reconstruction at the time of ACL surgery is not known.

The avulsed fragment of bone may be very difficult to see on the plain x-ray exam, and may be better seen on computed tomography.

[8][9] Segond fracture is typically the result of abnormal varus, or "bowing", stress to the knee, combined with internal rotation of the tibia.

Reverse Segond fracture, as its name suggests, is caused by abnormal valgus, or "knock-knee", stress and external rotation.
