Wow - that sucks big time and really sorry to hear that. Breaking a femur is no joke - I would think much longer than 3 months of recovery time, but hope it heals just as they predict. Did the police say anything about pulling cell records? Your poor bike too - that's a nice ride and I guess it's a write off? I hope insurance treats you well. Will you have to take the 3 months off work, or what will happen there.
Hope all goes well with rehab and the whole process - I've been there before a long time ago and paying attention to rehab is key.
When the time comes, and if you need it, I know an excellent personal injury law firm that is a stone's throw from, old city hall - PM me and I would be happy to give you the info. I used them to handle the closing of my case with both my own insurance company and also the other insurance company and the outcome was very favourable.
welcome to the femoral rod/russell nail club!
hottubs/baths really help to improve the flexibility in your knee joint. don't overdo it. it took me 11 years (with two other knee surgeries in there) to be able to comfortably squat again.
