My daughter, age 11, was diagnosed with Osgood-Schlatter syndrome? Will she always have the large bump on her knee?
No, not necessarily. The bump might decrease when the growth plate closes in that part of the knee. That age is generally around 13 in girls. If it does not get smaller, it most likely will not bother her in any way--even cosmetically. Every once in a while an Osgood-Schlatterer's bump is irritating as adult with kneeling; X-ray may show a small fragment or "ossicle". In that very infrequent instance, a minimally invasive surgical removal can be done.
