Hi @lukyme, I'm a year plus out from my TKR but have been fortunate not to have burning or scar tissue. There are a couple of other discussions that may provide some helpful information for you.

@contentandwell, @rmeddings, @randythehack and @ruthannejoan may be able to provide some suggestions.

I did find an interesting article but not sure it describes symptoms exactly.

Did the doctor say why he thought scar tissue might be the cause of your pain?
