Anatomy · Lower limb: Osgood-Schlatter disease

Sample item

A 13-year-old footballer has pain and swelling over the tibial tuberosity that worsens with kneeling and running. Radiographs show fragmentation of the tuberosity. What is the underlying process?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Traction apophysitis at the patellar tendon insertion

Osgood-Schlatter disease is a traction apophysitis of the tibial tuberosity caused by repetitive pull of the quadriceps via the patellar tendon in an active adolescent. It usually settles with rest and activity modification.

Option by option

  • A. Avascular necrosis of the femoral capital epiphysis

    Avascular necrosis of the femoral epiphysis is Perthes disease, presenting with hip pain.

  • B. Slipped upper femoral epiphysis

    A slipped epiphysis occurs at the hip in obese adolescents.

  • C. Stress fracture of the tibial shaft

    A stress fracture involves the tibial shaft rather than the tuberosity.

  • D. Traction apophysitis at the patellar tendon insertion (correct)

    Correct. Repeated quadriceps traction at the patellar tendon insertion injures the apophysis.
