I Have Intramedullary Rod(s) In My Femur That I Have

I have intramedullary rod(s) in my femur that I have had since I was 8 years old, now I am 20 and in the Marine Corps infantry and am experiencing problems with my IT band and patella femoral syndrome because the rods have become displaced and the amount of scar tissue build up. What would a surgery to get these taken out of my femur entail?
