What do I need to do to prepare for surgery?

Once you decide to have the surgery, you should schedule a checkup with your primary care doctor (internist or family practitioner).  He or she will order any special preoperative tests that may be necessary, and (if applicable) will advise you when to stop taking your blood thinners before surgery.

You are also strongly advised to have a dental checkup.  The reason for this is that dental infections can lead to development of an infection of your new hip prosthesis; surprisingly, many people are harboring chronic, low-grade dental infections but are not aware of it!

What type of prosthesis is used?

You should talk to your surgeon about the different bearing surfaces available and which may be best for you.  Regardless of the types of material used or brand of the prosthesis, all modern hip implants will allow you to whatever you want to do, within reasonable limits (see below)!
