Wondering if anyone else has a history of lipomas and if this might be related to AF. I seem to have inherited a predisposition to developing lipomas and these may be related to insults. My lipomas are on my arms, my torso, and my thighs, just like my dad’s. For example, where I have had blood drawn on my arm I have scar tissue that looks like a lipoma. Just thinking that this may be a heads up for anyone considering TKR — If I were armed with this kind of information prior to necessary TKR surgery, I would find a good AF surgeon!!
