I have many knee problems, not only from martial arts and athletics in general but from a growth disorder as a kid that put to much strain on my bones as my muscles grew. This is called Oshgoodshlaughters <sp?> disease and is not uncommon in young athletes.

A nuetral (the least common) This person has a perfectly nuetral gate, or walk, and needs no support.
A Overpronater (The most common) This persons weight shifts on the ankle side of there foot as they walk or run. Although it is a slight shift it puts undue stress on your knee and hips every step you take. This can be corrected with a 'stability' shoe.
A Extreme Overpronater This person is same as above but more dramatic overpronation and needs 'motion controll' shoes.
Go check out your local running/fitness store and look into some nice shoes. I recomend Brooks, Asics, Mizuno or New Balance. I started wearing stablity shoes years ago and its done wonders for my knees.
I second going to see another doctor. Maybe not a GP, but definitely a physiotherapist (around here, they tend to be quacks, but maybe they're good in the US) and maybe even a Chiropractor, if you have a very intelligent Chiropractor. (Mine tends to do more good than physios on soft tissue, but I think mine's a lucky find.)
