I am happy that you replied my thread. I know, you have lot of experience on this subject from my earlier posts. As you suggested, I have been diagnosed to have quadriceps tendonitis on my latest diagnosis. Actually, the pain is also presented above the kneecap area, even while I am riding (I can tell it now because I realised it just a moment ago while I was riding gently around the neighborhood). However, I had been told to have PFPS two years ago. And, in between them, I had an MRI scan and it showed that I have Grade II degeneration on medial meniscus posterior horn (is this the back of the knee? I have no pain on the back of my knee anymore). So, I can't be sure anymore. Maybe it is evolving from one issue to another. Anyway, I am not pushing and doing long rides on my touring bike anymore, just commuting. I am also doing quadriceps strengthening exercises in a daily routine and using foam roller to stretch hips, it band, quadriceps muscles. I am dealing with this issue since two years but I hope that it will go away soon. Then I can start again my longer rides with my road bike which has clipless pedals.
