You might try raising your saddle a little and/or moving it forward. These can lower the stress on the knee but could potentially throw something else out of whack. So make small adjustments and evaluate before going further.
Could do - I'm pretty happy with my positioning though, and don't want to mess with it too much for fear of messing up something in the overuse category rather than the trauma one.
The thing that hurts my knee is repeated bending motions. doesn't really matter if there is power or pounding or twisting or anything else that might normally bother a bum knee, it's really just that there is still a bunch of swelling under/in my patella, and that makes it painful to bend it all the way.
So, I suspect that's why rollerskiing feels fine - not a huge amount of bending, and the tempo is significantly slower than the 90ish bends per minute of cycling and running.
Basically, still waiting for this swelling to go down, and trying to not aggravate it too often by doing things like riding my bike...
Have you tried Voltaren diclofenac? It's essentially rub-on ibuprofen for joint and muscle damage and swelling. I got a tube over the counter in Canada when I severed my quad (not much good for that) and still use it occasionally if something really bothers me. Needs a prescription in the US.
I have rub-on ibuprofen, that we acquired when in Scotland. Seems better than popping the pills. But ice is more effective.
We actually drove past a woman using one of those elliptical bikes in Medford last weekend! It looked...erm...cool?
I still haven't shown you my sweet race-walking skillz.
Not really, no :)
