Well, for me personally it is interesting to see that a lot of you guys have started physical activities after a broken femurs so quickly. 3 weeks after surgery is nothing talking about a time that is necessary to at least partial femur recovery. The only thing that holds the pieces of the broken femur at this time is the metal plate, rod, or this weird looking apparatus, which is sticking out to the surface of the leg (in cases of very complicated bone injuries). When I had broken femur 4 years ago, I had to spend 3 months walking with 2 crutches and no load for the injured leg at all. In total, it took me 5 months to fully recover and be back in sport again. The metal plate and 12 screws were removed from my bone something like one year later. Now I don't feel any consequences (such as pain, any kind of discomfort, etc.) of the injury at all and the only things that remind me of it are x-ray photos and zipper-like scar on my leg. Therefore, I could advice from the personal experience that there is nowhere to hurry with recovering fom such injuries, because otherwise the consequences might be felf throughout the rest of the life.
