How serious is osgood schlatter disease?

Not serious: While this problem can curtail some of your activities especially in the active growing years, it usually ends once you have finished your growth.

No danger, just pain: The most common treatments for osgood-schlatters include rest/ activity modification, ice, compression, anti-inflammatories, massage and therapeutic stretching that focuses on the muscles of the upper leg (hamstrings & quads). Individuals with osgood schlatter may partipate in activity to limits of pain tolerance without concern.
