I had mine done about 18months back.
Two weeks was conservative! I walked out of the hospital like the surgeon said, what he failed to mention was that once the painkillers had worn off I'd be in agony!
2 weeks on the sofa dosed up on pain killers, managed to read 14 pages of a paperback zombie novel!
2weeks – pain droped to a level i could manage with paracetamol
4 weeks – enough movement to walk short distances arround the house, and swim front crawl with a pullbouy
6 weeks – enough movement to walk to the pool (half mile)
8 weeks – enough to sit on a weight machine and begin physio
10 weeks – sat on a turbo trainer for 10min at a time
12 weeks – could manage a rower
14 weeks – ride a bike on the roads
did manage a couple of 100mile road rides in the autumn, but think I tore it again in febuary 🙁
