At age of 82, I've had a complete left Hip replacement with a Titanium assembly. An extreme amount of preparation and work prior to the op and then during and after the operation to prevent any infection along with what they call an 'Operation guided by Robot' resulted in a new Hip, a very quick recovery, and no pain. Works like a charm with no issues on either my Motorcycles, the Spyder, or long walks. I completely forgot about it after a year or so, unless the subject is brought up. If available, the robot is the way to go. The Surgeon still does all the cutting, splicing, and placement, but the entire procedure is extremely accurate. No matter what I do, I am not aware of any issues, completely as good as new. Walking, day one.
