Good advice! In order of importance, 1) I would check the surgeons feedback. 2) Find out how much experience he has doing knee replacements, 3) ask what procedure he uses, 4) make sure he doesn't send you home next day. I had a double TKR and my Dr. used theStryker Titanium on both. I had the surgery on July 1 and at 6 weeks I am walking without a cane. I did all the things above to feel comfortable getting the procedure. Not all Drs will peform a double TKR, so I made sure he had experience. Bottom line, just do what you have to do to feel comfortable with this surgery. Good luck!
