Having said that my right knee objects mightily to two things - firstly it doesn't like too much horsepower, if i spin in one gear lower than I would otherwise like it is a bit happier.
Secondly - a sure way to upset it is for my saddle to be too low, even a little bit. It's a personal thing but I find that I need the saddle set such that with my heel on the pedal my leg is completely straight. This is standard wisdom as you're probably aware.
Some of my quick release seat clamps allow the seat post to slowly sink. I have to watch this carefully - checking before every ride.
Oh - and an expensive suggestion - you might try some pedals with a lot of lateral float. Time ATACs are very floaty and often written up as being good for people with troublesome knees. They do both MTB and single-sided-road versions.
