I went out for a ride recently. I always wear a knee support on the affected knee.

I went really hard to order to induce the knee pain. There was a strong reaction along the side of the knee cap and where the vastus medialis attaches to the kneecap. If you look at my attached photo below, just imagine the knee joint moving on the bicycle and how the highlighted area would move along the side of the knee cap. That's where I felt the pain. The sensation was that there was load of tissue in there that was all messed up; it felt like scar tissue. This was my original diagnosis and so I'm certain that the specialist who recently saw my knee was wrong in his diagnosis of 'jumper's knee'.

On the plus side, I was able to put my knee through that and it was still strong enough to keep going without too much adverse reaction. However, obviously it's something I'd like to correct.
