It was done to me. July 2008 a drunk driver hit me head-on while I was heading home from work on my Goldwing. 3 months in the hospital, almost lost my left leg - and another 4 years for the soft tissue to heal enough to get a knee replacement.
I would post a hospital picture after the accident, but it's REALLY awful. The knee replacement was a (pardon the pun) walk in the park!
op i had the same exact injury as you 2 years ago. i can see we both had the same external fixator. even our metal matches and is in same location. having the cage bolted to your leg is the worst part. make sure you get a good p t person. mine was a joke. i never did get back full range of motion but i got most of it back. im really suprised how DECENT my knee feels. good luck. you should feel ok after the pain fades lol.
