* Rest. This injury needs rest if it is to heal properly. Only do as much exercise as it will allow without causing pain. Weight bearing exercise will make it worse. Keep your sessions few and high quality rather than train every day.
* Apply ice or cold therapy to the knee regularly throughout the day to reduce pain and inflammation and particularly following activity or sport. Ice should be applied at least three times a day for 10 to 15 minutes. Ice massage with an ice cube is a convenient way to apply cold therapy to a specific area such as the patella tendon. * Gently stretch the quad muscles if comfortable to do so.
* Use a knee support or knee strap to help reduce the tension on the knee.
* See a sports injury professional


What can a sports injury professional do?
* Make a correct diagnosis to confirm the existance of Osgood Schlatters disease and make sure it is not anything else causing the pain. * Use sports massage techniques on the quads and patella tendon.
* Prescribe an exercise programme that will allow you to do as much exercise as possible and get the best results from your training.


In extremely severe cases:
* X-ray to see exactly how much damage has occurred.
* Apply a plaster cast for three weeks if pain is severe.
