Osgood-Schlatter Disease

Question 1

What is Osgood-Schlatter Disease?

Answer 1

Inflammation at the tibial tuberosity where the patella ligament inserts causing anterior unilateral knee pain

Question 2

Who is typically affected by OSD?

Answer 2

10-15 year olds
Males

Question 3

Answer 3

Multiple minor avulsion fractures occur where the patella ligament pulls away pieces of the bone

This causes growth of the tibial tuberosity causing a visible lump below the knee

Question 4

What happens to the lump below the knee in OSD?

Answer 4

Initially tender due to inflammation

As the bone heals the lump becomes hard and non-tender

Lump is then permanently present at the tibial tuberosity

Question 5

Visible or palpable hard and tender lump at tibial tuberosity

Pain in anterior knee

Pain exacerbated by physical activity

Answer 6

Reduction in physical activity

ICE

NSAIDs

After symptoms are settled, physiotherapy to strengthen joint and improve function

Question 7

What is the prognosis of Osgood Schlatter Disease?

Answer 7

Symptoms fully resolve over time
