I had mine done in March, plus they went ahead and scraped out the arthritis that was already there (at least that's how they described it). The next morning, the physical therapist yelled at me for not being on crutches, so for the next four weeks, twice a week, I dutifully used the crutches to go in and out of their office - and never used them anywhere else! It took me 6 days to get to where I could pedal a complete revolution on the stationary bike. I didn't get back on my trike for 3 weeks, but that was due to bad weather, not to anything about my knee. The only day of work I missed was the day of the surgery, but I milked it to get an extra 2 days of working at home that week; I could have made it in to the office, but decided I'd rather stay home than deal with traffic. I'd say that once you can handle the stationary bike without pain, there's no real reason to stay off a normal bike any longer.
