Zumba poster here. I don't think Zumba is particularly hard on the knees. You can self-adjust any particular move to low impact, if necessary. I quit running because of some early knee arthritis, and I'm 22 weeks pregnant, and I haven't noticed any problems at all. I still do almost all of the moves that involve leaving the floor. I just make sure to land carefully and softly.
It's a great workout, and the time flies by because it's so fun! It's a good complement to elliptical training (the other exercise that I do). Instead of the repetitive movements, all of your muscles are worked in a variety of ways. I was having some high blood sugars while pregnant (and only doing elliptical). After I started Zumba the problem disappeared. I think that having more muscles involved in my workout made a big difference in allowing my body to metabolize glucose more efficiently.
