This is true, although it looks like in this case it may be more useful than just another pain killer, in that if you can reduce the joint pain, people might be more active, which may help them lose weight, which may reduce joint pain. If it's safe to take long term (reading between the lines, sounds like it might be compared to other pain killers), then it could have lasting impact on patients beyond them taking it, which is a good thing.

this is for OA, which means people dont have much joint left in the first place. That is what causes pain. not feeling pain will not turn them into marathon runners
