@comeoutdancing Yes...very rare. And what makes it intresting is that I had a left hip replacement five years ago and had no post surgery pain then either. There is only one variable that applies to both: the same surgeon.

My surgeon is extraordinary. He was an engineer before becoming a surgeon and he is the primary inventor of the minimally invasive Superpath method of hip replacement (that is what he did for me). He also gave me the extremely rare bicruciate retaining knee implant (BCR). In 99+% of TKRs, the ACL is resected and in many cases the PCL is as well. In a BCR the surgeon retains both and protects them. But the implant is different and the surgery is more complex so you only want it if your surgeon is extensively experienced at it. There is a video on the internet of my surgeon doing a BCR in 2020 at an Orthopedic Innovations Conference and he has now been doing them for at least a decade. I think there are only a handful of surgeons in the US doing BCRs; I am aware of only three.

I attribute the success as follows: 5% for my work reviewing procedures and finding Dr. Chow; 5% for luck (good in my case); and 90% for the skill and experience of Dr. Chow.

Surgeons are professionals and like all professionals they vary in their skills. Find the positive outlier like I did and you will have maximized your chance of a great recovery.
