Hi Max - my son has been having probs with his left patella since January this year, he has been to GP, sportsmed, chiro, physio, podiatrist, they keep giving him stretching excercises which assist have had orthotics which also assist somewhat, but overuse tends to flare it up. The ligaments and tendons are not keeping up with his growing he is 12. He wears a knee protector as he tends to continuously knock this knee and ices it after a game. He has also had a lot of problems with his feet a condition called Sever's has had this for 18 months or so but it seems to be settling but we have had to restrict the amount of b/ball he plays. Unfortunate thing is it affects his fitness and running where he once was one of the fastest at training he now runs at the back of the pack, and the only thing I think that will completely solve this condition is time.
