What things have to be taken care of for a person wishing for a knee replacement surgery?

Find a surgeon: You would need to see an orthopedic surgeon who would arrange this /you would need to be medically evaluated as to you general health and ability to undergo anesthesia and surgery this usually means a visit with a medical doc like an internal med doc and some lab testing maybe an ekg ( usually done for those with ^ blood pressure/ then it takes a good bit of "paper work" most pts do well.
