Wow!! That's awesome!! I just had 18 weeks post surgery yesterday! I really want to start up my walking again, as I haven't walked much in the last year, due to the pre-surgery knee being in such bad shape. I'm just taking it slowly, one day at a time, with regard to increased activity. I've been back to work for 8 weeks now, and since my job involves a lot of physical activity, I have been icing my knee and elevating my legs in the evenings, as I have been having some minor swelling and aches. Thanks to BoneSmart, I discovered that minor swelling and aches are considered normal parts of ongoing TKR recovery. So right now, the majority of my leisure time walking involves walking around the grocery store or WalMart, lol!! Hoping to increase that to walking around the block a few times pretty soon!!
