Hi Nirvana,
I can imagine your impatience... nobody answering you but it is holiday season in the northern hemisphere...you know
Have you looked around this site and googled information about O.Slatter?
What exactly did your doctor see on the Xray...is your tuberositas still intact?
To answer your questions...
I think it is worth your while to go to a good (sports)(paediatric) physiotherapist (physical therapist).
You will be assessed and given advice including exercises you should and shouldn't do.
Every person is different and everyone reacts differently to a problem (disorder) and that is why you need to see someone. Get hold of your Xray and take it with you.
With a bit of luck you will only need one session.
I wish you all the best.
Esther
