Osgood-Schlatter disease

Abstract

Osgood-Schlatter disease is an avascular necrosis thought to arise from overuse of the quadriceps muscle during periods of growth. This causes a traction apophysitis at the tibial insertion of the quadriceps tendon. The most common symptom is anterior knee pain that worsens with exercise. A tibial bump may be felt and can often be seen on x-ray. Treatment is usually conservative. Surgical excision is only necessary in severe and treatment-resistant cases.

Epidemiology

  • Age: adolescents; on average 9–14 years old
  • Sex: > (3:1)[1]

Epidemiological data refers to the US, unless otherwise specified.

Etiology

References:[1][2]

Clinical features

  • Anterior knee pain that is worse with activity and is reproducible with extension against resistance
  • Proximal tibial swelling

References:[1]

Diagnostics

  • X-ray
    • Anterior soft tissue swelling
    • Lifting of tubercle from the shaft
    • Irregularity or fragmentation of the tubercle
  • Ultrasound: soft tissue swelling[3]

References:[1]

Treatment

  • Mostly conservative (rest, ice, NSAIDs )
  • Strengthening and stretching of the quadriceps muscle
  • Generally resolves once full bone maturity is reached
  • Surgical excision of intratendinous ossicles in severe cases
