Two problems with this statement.. your ortho really can't speak for what is comfortable for *you* on the bike, and just being a cyclist does not make him an expert on bike fit... especially because there's a fairly wide margin of what is "okay" on paper, but probably doesn't work in actual practice. 172.5 cranks may be fine for many.. it sounds like odds are good they're not fine for you.

I'd try shorter cranks.. because I think you'd know right away if that helps or not
