Broken Knee

Hi Ladies! I fell while sprinting on Wednesday and hurt my knee. I was not able to walk on it and went to see an orthopedist the morning after. I have femur fracture( At the very bottom left side of the bone) and possible soft tissue/muscle damage. I got an MRI on Friday and am seeing another ortho tomorrow. I have a bad pain that shoots down to my ankle(which is swollen) and overall pain. My knee is swollen and bruised Does anyone have any ideas or experience with this kind of thing? If you are a doctor I would also love your advice/opinion. Thanks!
