I couldn't find the answer to this using the search facility. I have a pain in the right knee. it only hurts with the knee fully bent, the top left side of the patella (well under it I guess) hurts if I press on it.

This seems different to the typical patella complaints - where the pain in centred at the bottom where the patella and ligament join.

Any thoughts? It is sore but I can still ride and is improving.
