What is Osgood-Schlatter Disease? 

Osgood-Schlatter disease is where there is an extra bone growth on the bone below the patella (knee cap). It is common in active adolescents especially those participating in sports that involve running, jumping and changing direction. The disease is associated with growth spurts and can occur in both knees in approximately 30% of cases.

What causes it? 

The exact reason for the onset of Osgood-Schlatter disease is unknown. Repeated stress of the quadriceps muscles on the tibial tuberosity and abnormal quadriceps tightness can lead to an enlargement of the tibial tubercle. Onset may be caused by the relative imbalance of strengthening quadriceps muscles compared with the growing bone. Other contributing factors include over training, poor or inadequate foot wear and poor lower limb biomechanics or running technique.

Signs and Symptoms of Osgood-Schlatter Disease:

Pain, tenderness, and swelling around the tibial tuberosity which is the bony prominence located just below the knee cap.


Conservative treatment consists of rest from painful activities, icing, and NSAIDs until pain levels have reduced. A strengthening and stretching program will be devised by your Chartered Physiotherapist that involves both increasing the strength and flexibility of all the muscles around the knee.  Your Chartered Physiotherapist here at Somerton Physiotherapy will also guide you through a return to sport protocol eventually back to your pre-injury status.
