Joint replacement

I am a 5 year  stage 4 kidney cancer survivor. I have a Knee that needs to be replaced.

I cannot walk or stand more than 15-20 minutes could hardley get in or out of car.

I am on Sutent(chemo) for 3.5 years  my oncologist said that should not be a problem.

I have tried a few "Good Doctors at major hospitals in the East"  Phila area.

But cannot get a doctor that would think about doing the replacement since I am on chemo.

I have tried Jel injections nothing works.

If there are any Doctors out on this network  that would recommed where to go that they can help me out

any suggestions.

Thank you for your time ...
