DaveI can fully understand the removal of the Femur hardware but are you also taking the TPF hardware out at the same time because that's got to be a huge operation, do you really need the tpf hardware out now or is it harder to get it out in 2 - 4 years time closer to when you get knee replacement, or is it the case that once hardware comes out the holes will get a chance to fill in before the knee replacement happens.Andrew
