If you choose to have this surgery, then it is recommended that you choose a surgeon who has performed this surgery for many years. This will help ensure that the chances of complications are lessened immensely. If you do not care about the risks that might happen to yourself, then consider choosing a different doctor who can answer all your questions. If they cannot answer them to your satisfaction, then consider getting a second opinion from another doctor or hospital. You should do this regardless of whether or not you decide on getting knee replacement surgery done on yourself or someone else.
