There are many excellent surgeons who don't do "branded" knee replacements (like Jiffy or Nano) but nonetheless do excellent work.

I have an incredible surgeon. He replaced my left hip three years ago and I had zero pain and don't even consider it any different from my natural right hip. Almost six months ago he replaced my right knee which was badly misaligned and, again, I had no post surgery pain. His recovery protocol is to essentially rest the first two weeks with regular icing and compression to reduce the inflammation and then start PT in the third week. That third week my therapist measured my ROM at 122 and my extension as flat.

My magician (AKA surgeon) did a mini midvastus cut, did not use a tourniquet, put in a bicruciate retaining implant (BCR) so I still have all my ligaments, fixed my severe valgus misalignment with a Functional alignment and did a plastic surgery close. Before my surgery, I told him that I (an 80 YO male) wanted to be back on the golf course by the end of the fourth week. he replied that this was an aggressive target but he was up for the challenge. On the 27th day after surgery, I was playing golf.

My magician has a traveling practice with patients coming to him from all across the country and a section of his web site is for that purpose.

Why am I saying all this? Because he doesn't accept Medicare nor Insurance so his fee is payable separately but the rest of my cost was covered by my PPO Medicare Advantage Plan. But his fee is substantially less than a NANO surgeon fee and I would put my guy up against a NANO surgeon every day.

Finding a great surgeon who does minimally invasive procedures is a major step toward a rapid and painless or minimally painful recovery. But one is not limited to the branded knee processes. The best surgeons are out there on their own (such as mine) or in specialty locations. Mayo, the Cleveland Clinic and the Hospital for Special Surgery are all excellent.
