The answer and the reasoning

B. Pellegrini-Stieda lesion

Pellegrini-Stieda disease is calcification or ossification at the femoral attachment of the medial collateral ligament after an old injury. A Segond fracture is an avulsion of the lateral tibial plateau linked to an anterior cruciate tear. Osgood-Schlatter affects the tibial tubercle.

  • C. Osteochondroma

    An osteochondroma is a bony outgrowth continuous with the cortex and marrow.

  • D. Segond fracture

    A Segond fracture is on the lateral tibial plateau.
