Tennis is hard on the knees, elbows, and shoulders

I've played years of tennis and I can confirm that they are very hard on your knees. You constantly turn on a dime, twisting around to go in the completely opposite direction. I don't know what kind of shoes are required to give your knees good support in that scenario. The ones I have keep me from slipping (which is always a good way to avoid injury!) but I don't know if having such good grip is actually worse on your knees since it allows you to stop and turn more suddenly. Anyone know more?
