  1. Hi.

    Segond fracture and knee effusion.

    ??suprapatellar effusion too.

    Can’t figure out if there’s another abnormality.

    • Hi Simon,

      Thank you for your query. You can view the answer at the end of the post. The 3rd abnormality is the compression type injury to the lateral condyle of femur which is also seen in association with an ACL tear. When the dent is more pronounced, it is referred to as the lateral condylar notch sign.
