Ehh, I don't think thats true, there's also a big difference between dynamic stretching (leg swings, stretches where you move), and static stretching (just touching your toes or something - stretching without movement). I've always heard its best to do some dynamic stretching and light cardio before exercise and then light cardio and static stretching after.
I generally do a warmup (lame I know), consisting of some leg swings, a short run in my ski boots (gets my legs working), and then a couple mellow warm-up runs of just various size turns. This gets my muscles warmed up and nice and loose.
After skiing I drink a shitload of water and try to stretch out immediately after. I use a foam roller as well. Sometimes I'll put some ice on my knees or whatever. I find another really important thing with stretching is to stretch your whole body - go nuts, stretch everything. A lot of knee pain is caused by tension in other parts of your body, if your ankles or calves are tight they'll pull on your knees.
I have a chronic knee condition that's caused me a lot of pain over the past few years but making sure I do a legit warmup and cool down, and stretch every day, has really helped me.
