Could you tell me what is the treatment for osgood schlatter disease in the knee of a 19 year old?

Doubt diagnosis: Osgood schlatter disease is a problem of immature growth centers.The tibial anchor point for upper leg muscles is soft and unstable and activities involving the upper leg muscles pull at the growth plate, and the shifting triggers pain and swelling. Treatment is rest.At age 19, this center should be fused to the bone and stable.Knee pain is common to many other problems more likely at this age.
