Posted this on another message, but is more approriate here...
I just had right TKN 10 weeks ago - what a difference it's made! I'm very heavy and figured that would affect my recovery time and worried whether the new knee would work. WRONG! I was in the hospital 3 days, walked with a walker for two weeks. Walked with a cane for about two days.
At five weeks, was on the golf course playing two or three holes. At 8 weeks, playing 18 holes of golf (but tired afterward).
BIKING... couldn't wait to get on the bike again - it had been over three years since I could bike. The biggest issue starting to ride again was that I couldn't make an entire pedal revolution. It took several tries on a stationary bike over the course of a week or so to finally get that range of motion.
So... here it is 10 weeks today after TKR - I'm riding 10 miles at a time. The knee is stiff and hurts a bit when I start out, but after a mile or so, the (minor) pain goes away. What a JOY to be back on the bike. I'm slow... because I haven't used the quads for three years, but that will improve with time.
As others have said, I don't know why I waited so long to have it done. With the pain meds you are given, there isn't a LOT of pain. PT is a PITA, however, is necessary. I'm a great believer that having a positive attitude and willingness to work hard at PT is the reason my TKN has been so successfull.
Looking forward to my first 20 mile ride in three years .... in about two weeks!!
