With increasing osteoarthritis in aging runners, there are some creative, if pricy solutions. I think the eliptical trainers are good for low impact but if price is no object, here are the cutting edge devices.

2. I have an elliptical and love it.

It's the only piece of exercise equipment that I've never gotten bored of. Going on 9 years with the same $499 model I bought at Sears.
