I had a severe, complex ,mulitiple tibia plateau fracture from a motor bike injury. They put four crews in and I needed a second op to remove a stray bone chip preventing my knee from straightening. I have had my metal in for 3 years and am getting brave enough to get them removed. I dont really battle with my screws but one pinches the skin if I kneel on it. I also fear that they act as conducters when the weather is cold making my knee slightly stiff.
I train 3 times a week for two years and have got my leg to 90% normal.
After surfing the net it seems that I wont bother with removal anymore as it seems that the surgeons advocate removal only if pain nessestates it.
