Hi Kristi,
I agree with Milly. There has to be a reason why you have chondromalacia. I had the same problem and was seeing an OS who was telling me try physio and various treatments, all of which aggravated my knee more. In the end I got fed up and went for a second opinion, this OS did an MRI and other tests, my chondromalacia was due to maltracking and the back of my kneecap was rough where it should be smooth. He preformed a lateral release and cleaned out the back of my kneecap. If I was in your suitation I would definitly be looking for another opinion so you can get your knee sorted and hopefully pain free. I have OA in both my knees so I still have pain especially in cold weather, but I think the OA could have been avoided in my left knee if I had got is sorted sooner.
Good Luck,
Cynthia
