Bob went to see his knee doctor today - post op three weeks - and doesn't have to come back for a whole year. He just needs to keep his knee moving (inactivity will build up scar tissue which is the enemy of a complete recovery), walk 20 to 30 minutes or more a day, do his exercises, and ice after them. That's it. No special physical therapy needed at all. He can take Advil if he has pain and has permission to drive – even though he’s been driving for a week and a half already.
This is definitely a partial knee replacement success story.
