You feel like your quality of life has deteriorated because of knee pain. The list of activities you can’t do seems to get longer every day, including simple things like playing with the kids, working in the garden, playing golf, or taking an evening stroll.

You do anything to avoid climbing stairs.
You’re buying more ibuprofen (or some other pain reliever) more than ever before, but it’s not helping anymore.
