3 weeks post op tomorrow and I went on a bike at the gym and had no problems or pain at all!!
Cycled for 10 mins at level 7 out of 10 at about 60RPM, could have done more but didnt want to push it too much.
Home now and still no side effects at all.
Also lifting 35kg on my bad leg with the legpress, the same as I can on my good leg, need to lift that a lot more, but a good start and equal strength!
