Flur, I third seeing a PT and working with them on cycling-specific questions. Your PCP can refer you. I don't know what advances have been made in PT in the past 15 years, but I suspect a lot. More to the point, the equipment questions that affect cyclists' knee alignment are unique to the sport. So even if your PT was up to the level of 2008 science, if you didn't work on cycling, there's more to be gained there.
