Nanoknee, is it better or merely hype?

I am so curious to find this out, too! On Facebook, there is a Nanoknee and Jiffy knee (I think the same type of surgery) and most have great outcomes. From my research, they 'can' use (maybe you have to ask for it) an On-Q pump that gives numbing for up to 3 days...which is why I am researching having mine done with one of them. The surgeon I have seen (NOT Nano or Jiffy) says the nerve block is only approx 12 hours for him, and that scares the heck out of me!

My knee is totally shot, even with sewing it up. Is this Nanoknee legit or not-I have no idea. However, I suggest that gather all your concerns together and talk to an anesthesiologist because I assume that is who will be doing the work. That includes telling them of how concerning this or that is for you. I am a guinea for surgeons so I want to avoid it. One of my top concerns in the realignment factor for my twisted leg/knee. This place says that they custom fit the knee and use imaging. I will study it more, and wish you good luck and health.

I had the pump for longer than 3 days! I think it was more than one week.

Jiffy knee and Nano knee use a subvastus method. My surgeon used a midvastus method and the 12 hour nerve block. My surgeon is incredible and after the nerve block wore off I still had no meaningful pain. 21 days post surgery and I was measured with my flex being 122. Then I went to my golf club and tried hitting some balls on the range. I swung very easy but I could hit the ball and I will be playing with my regular foursome on Tuesday which will be 27 post surgery.

Jiffy and Nano are marketing gambits but they do work well for non problematic cases. My surgeon said he used the midvastus method instead of the subvastus method for two reasons: (1) he is leaving a path for any future revisions should it become necessary; and (2) He was doing a bicruciate retaining implant (BCR) and a functional alignment (I was severely misaligned) and these two require more complex surgery and the midvastus approach gives him a wider field to work in.

The subvastus approach goes under the tendon and muscle; the mini midvastus approach goes through the muscle fibers and also skips the tendon. The subvastus approach gives slightly less pain than the midvastus but both are way superior to the traditional approach which cuts both the muscle and tendon and then repairs them at the end.

My surgeon is an engineer by training and is the principal inventor of the Superpath method for hip replacements and has a number of patents. Nonetheless, he says (and I agree) that the most important qualification is extensive experience doing the exact same procedure. I would look for at least several hundred such procedures. If a surgeon had been doing traditional hip surgery, had recently moved on to Superpath but had only done 15 of them so far, both my doctor and I would rather have that surgeon use the traditional (most likely painful) method because he is not extensively experienced on the Superpath method.

So go ahead and check out the Jiffy and Nano surgeons. For example, there is a Jiffy knee surgeon in my area that has extensive experience. My surgeon is also a revision surgeon (he spends about 20% of his time revising others' work) and he told me that he has not seen anything bad out of this Jiffy doctor. That is a compliment.

At the end of the day, there is still an element of chance involved. But selecting the right surgeon can significantly improve your chances of getting a good recovery.

For whatever it is worth, here are my surgeon requirements:
(1) subvastus or midvastus approach
(2) BCR implant (95% of knee surgeons remove the ACL and a large proportion also remove the PCL. They then let the implant try to serve the function of those ligaments. A BCR retains both ligaments. So after surgery I still have all my ligaments and they are working. But the surgery for doing this is more complex.
(3) Modern alignment repair meaning NOT mechanical alignment (which was always the gold standard and is now fools gold). Preferably Functional alignment but kinematic or inverse kinematic would be okay.
(4) NO routine use of a tourniquet
(5) Extensive experience doing the above
(6) great mind
(7) Great hands.

I found someone who met all 7 of these. But if you can't, #5 is the most important.
