I just found this website
http://www.cptips.com/knee2.htm. Thought I'd post it for others looking for decent advice from a website that's not trying to sell something. To me it sounds likeMediopatellar plica syndrome or Pes anserine bursitis. I'm gonna try a short ride in the small chainring this evening to see what happens. I generally subcribe to MEAT treatment over RICE treatment if my injury is less than totally catastrophic, as I really can't fathom the idea of extended time off being a good thing except as I said in the case of a major injury. I have a feeling that tonight's ride will be telling.
I have also been raising my saddle incrementally as I had gotten used to it being on the low-side when I was rehabbing a back injury last season, so I think I'll drop it back down a touch.
