Yo, thanks for asking. I had my arthroscopy done three weeks ago as of today. Was able to jettison the crutches after 24 hours and do an easy, easy bike ride within one week. No PT with a therapist but I've been doing the prescribed exercises and inching up the ride time by 5 or 10 minutes every day or two as my knee allows. I rode for 1.5 hours the day before yesterday and it was a bit sore the next day.
Overall, I think I'm recovering like I should be but it does suck to be losing fitness as the days slide by with no intensity.
