VW54, this is a fantastic progress report in spite of some limping; hurrah! Now, about that limping....does it hurt when you walk? If not, is just your old habit and perhaps you haven't placed all your trust in the new knee yet? If it does still hurt when walking, have you mentioned this to your OS? With all you can do, especially going up the stairs (I'm assuming without pain?) and the cycling (also pain-free?) it does seem a bit odd to limp while walking, but....old habits die hard. Very hard! One more question: Are you wearing new shoes when walking? If yes, great. If not, get some.
