 Yeah, full knee on the left, and then if that goes well, my right one will be next. Yeah, my dad had that done, but, I mean, he was not able to straighten that leg at all. Not at all, but, I mean, he couldn't straighten it completely. So he had very good results with that knee surgery. So I think that after it's done and you heal up from it, I think you'll be in good shape.
