Welcome scooterboy - you'll find a lot of information on this site - those of use with TPFs usually hang out around The Specialists Office ---> bone breaks around the knee.
As far as seeing you OS, I see the PA first for about 10 minutes then the OS for about 15. The PA basically reviews the xrays, asking me about any changes and has me do some basic leg movements. The OS usually manipulates my leg, goes over the xrays with me, discusses future treatment and answers my questions. If I were you I think I would get an OS that actually wants to deal with patients.
