I hope it feels better soonb. My daughter had a knee replacement a couple of years ago and it is still giving her pain. HOWEVER< her problems were caused by a bad accident way back 20 odd yrs ago - she had all leg bones broken, pelvis smashed and ankle too. her ankle is now totally arthritic but wasn't giving as much pain as the knee, when the Dr asked if she wanted her knee in the same alignment as it was or whether she would prefer it in alignment ready for when she has to have the ankle replacement - she chose the new alignment and I think that is why she still has pain.
