Back but with some bumps in the road

I am in the same boat.  I have a patellar that is out of line and I believe some arthritis is starting to set in.  Every leg exercise, light or heavy, even HIIT on the elliptical (running is out of the question) ends up in a good amount of pain.  I would love any suggestions on how to get in a leg workout without struggling through a very painful workout and then taking a bottle of ibuprofen to get through the rest of the day.

stay away from the training that's hurting you. 

unfortunately, for me, all leg training causes a good amount of pain and I can't stop training legs.  Also, HIIT causes a good amount of pain, but according to everyone these days, HIIT is the only type of cardio that is effective for fat loss.  I am so frustrated and to the point where it hurts to go up and down the stairs on a daily basis (and to walk on a leg training day).  What is one to do?

Mary has summed things up in a few words.

Not easy to do, if you love your training. Being the age I am, I suffer from my share of aches and pains, but you have to accept what you can and cannot do. You will probably find that most people, whether it be sooner or later, will one day have to make the decision to not do certain movements at all, replace them with something else or to work around them. I think only you can answer that for yourself. It is only you that knows what makes you uncomfortable and what doesn't. Not much help, I'm afraid . . . . . .
