Having run a bike with 165s for a while I got back on my CX bike, with 175s, and the aching knees returned in pretty short order.
Pretty strange what you get used too, I have ridden 175s as long as I can remember, and always put the knees etc down to getting old( which it is of course, to some degree) Who would have thought that 10mm could make such a difference!? (feel free to insert inappropriate humour here
) It felt really cramped riding the CX bike, like I was all hunched over?
