How did you get rid of your hip pain?

If this pain is after the knee surgery, Mom needs to call her orthopedic. She could be favoring that knee and throwing her hip off. Or, she has arthritis and has aggravated it.

I'm not sure what you are asking Hiner, is this your grandmother with hip pain as a complication of the surgery or something else? In any case follow what PT has suggested, the advice I've heard from those who suffer from painful joints is that exercise is the best medicine. (Ice and NSAIDS too).
