Hi Jenny,
I only use the term 'stress ganglion' as my own term...but I'll certainly make the effort to find you out the technical word and some related information this evening - if you can wait that long.
Regarding the Osgood Schlatters, yes, I do still have the lumps in my knees - considering they're bone, I can't see them going away anytime soon

They are still tender if I hit them really hard, and also ache if I keep them in a bent position for a long time (like if I sit resting on my lower legs...a little hard to describe, but I think you know what I mean...). I think it's probably just something I'll have to live with - the doctors never really gave me any advice other than 'you'll grow out of it' - something which I haven't seen to have done. It doesn't really cause me that much of a problem nowadays like it used to - so I just put up with it. There's always surgery you can have, but I don't really see the need...
I'll search you out that information asap - and if you have any more questions about knee bumps, don't hesitiate to ask
Thanks,
