I'm trying to build up my lung capacity but I can't run do to knee problems.

It is impossible to increase your lung capacity. Lung capacity is genetic, mostly correlated with your height.

Try doing interval training on a bike. You should see similar cardiovascular responses with less stress on your knee.

I'm a trained singer and have a few lung exercises that we use to build up our lung capacity. One is to take a deep breath in and then slowly make a hissing sound releasing the air from your mouth. You keep releasing the air until you run out. Like a tire slowly leaking air, see how long you can go. Do this at least once a day and if should help! :)
