Dr. R. Scott Oliver: I’ve been asked about all the recent advances in hip and knee replacement. There may be some patients who have had poor outcomes in the past, but over the last 10 years, we’ve had dramatic advances for each one of our patients undergoing hip and knee replacements. For example, since 2004, I’ve been using computers for everyone of my hip and knee replacements. We’ve been using new techniques of smaller incisions, less muscle damage. Patients have been getting out of bed the day of surgery. We stopped using strong anticoagulation, we are simply using aspirin on many of our patients. Patients are coming back within three weeks just using a cane or even less just walking in the door. And their pain is less, they are doing much better, they are happier. Lots of times we can tell that that we have a great result because they come back for the second knee replacement within four to six months. That’s when you know you’ve done a great job.
