I am much more mobile than just a week ago. My cane stays at my desk or in the house and is rarely used, except for longer treks such as Costco. My legs aches at work, but I think that is more due to the chair and office than anything, usually better at home where I can put it up most of the time.
I work on the stationary bike and elliptical at home, probably not as much as I should, but it helps. All of the house preparations have been removed so we are getting back to normal.
All in all I am doing just fine for 7 weeks into a new knee.
