Here in Queensland, physio see you in the hospital for 2 days, give you print out showing you what to do for exercises, and supervise you through those exercises for those 2 days. Then you are on your own.
Instrctions you are given upon discharge is see your GP at 10 days for removal of dressing, and re-dress if necessary.
I had a heavy shink wrap type clear dressing, very tight but not uncomfortable over the cut, you could see gauze dressing underneath it, when taken off by GP, very pleased, no stitches to be taken out, melting stitches he said, then dressed again in light gauze for another week, just for protection, as still very raw and not healed completly, with follow up appt for 7 days time.
Later as I was having problems with gait, and foot drop, post left hip replacement, which I hadn't had with my right hip replacemnt 15 months previous. GP arranged for me to see physios again at local hospital, big help in getting me using right muscles, I was very strong in some muscles, but others were very weak, and needed particular help in getting right, followed instructions and got myself right in a few months of intensive help.
I also when my cut healed to the GP's satisfaction got back in the local heated pool, and did my exercises as per the hand out from the hospital, thats why the physios found I was very strong in some muscles, this is something I have done for a long time, in the years prior to my surgery to help my systemic arthiritis, and are still doing post surgery, twice a week, has made a huge difference to my general levels of fitness.
