I think once an individual's determined that they want to have surgery, there are a lot of steps that can be done to maximize the benefit of the surgical outcome. And I think most surgeons will talk about modifiable risk factors and there's well known issues with smoking, being overweight, having poor muscle development and those are things that can be easily addressed. Now they might not be readily accepted but they can make a huge impact in how a person fares during and after their surgical procedure.
Now when I talk about smoking, obesity, diabetes control those are national norms that have been established for not only good outcomes but to protect against complications and bad outcomes. So the surgeon really has a responsibility in discussion with the patient, to say these are things that can lead to a much better outcome. If you're a diabetic patient and your blood glucose is poorly controlled your risk of an infection or loosening of the components, increases exponentially because your sugar metabolism affects how your bone reacts, how your blood flows and how your skin heals.
