broken femur

I'm a ski instructor,broke my femur on the last day of the season - clean break, surgery to put in a nail screwed at the hip and above the knee. 7 weeks since surgery.I'm walking unaided, doing daily excercises given by physio and having physio once a week.But very stiff legged. Can bend knee 55 degrees - 62 with the physio and some fluid build up on the knee. Had follow up x ray last week all looking good, bone growth doing well. But surgeon said amount I can bend my knee was hopeless however the physio says this is totally normal.?Hope to start stationary bike and swimming . Is it realistic to hope that I will be able to ski easy runs and with beginner clients only in 7 weeks time? so 13-14 weeks after surgery? and then to continue working for the winter season? I am very fit and active and have been thru this before with a broken fibula that was plated and screwed and was skiing 7 weeks later. Am I being totally unrealistic to think I could ski 13 weeks after the injury...?

Biking is a good option for you knee to help get ROM back.
Is your ROM getting better? if it's getting better and continuing to do so then go with it for now, only be worried about it if your getting nowhere. - most surgeons want you at 90 degree before they are happy.
Isnt ski season pretty much over? where are you skiing? - sorry I'm in the north and don't ski to be fair. Probably a good idea to visit a physio that is a skier? are u doing that.
The fibula isn't weight bearing really so you would be and about on that very quickly - the femur is a much stronger bone and takes alot to break and hense takes alot more time to heal... I would say that at 13 weeks you may be ambitious but I don't ski so don't truely understand the amount of force required.
