You went back to work very early last time. It's unusual to be able to do that.I think I'm beating myself up knowing that for my prior LTKR I was back to work already by this time.
I too was born with birth defects about my lower extremities! I had to have my legs repositioned and wore braces and casts for my first year of life (so mama tells me).I can relate. Both knees had birth defects so they've been bad all my life.
