Birth of a Knee

The revised knee is 3 weeks old today. I have been driving my car since 13 days after surgery.  The scar is healed, the swelling is mostly gone, the physical therapist seems to have run out of exercises for me, and I pretty much forget about the surgery during the day, so what's the big deal about a total knee replacement.  It's more like having a dental crown-like cap placed on the ends of your leg bones with the insertion of a small cushion for separation.  Truthfully, I'd rather have my bones worked on than my teeth anyway.  I still get nightmares over a tooth restoration process called a crown-lengthening which was once proposed but turned out not to be.  I still think about the surgeon I almost went to who has all his patients restricted to a walker for 4 weeks.  Word is he's very good, but 4 weeks with a walker!
