@Jamie @spyac3 Jamie, I would definitely agree with what you said. But I would also like to mention some considerations. My surgeon is nicknamed "the wingman" because he specializes in shoulders, even though he does knees, broken bones, and arms. BUT, I had two additional things to consider - when I saw the "knee specialist" here, he dismissed me when I mentioned a possible autoinflammatory or autoimmune issue, and said I needed a partial replacement. While I was considering a partial, I just *happened* to meet 4 people who had total knees by my current surgeon, and 3 more that had either a shoulder, leg, or arm done. When I asked around to the local nurse practitioner and my physical therapist, they all emphatically said this surgeon was good at every joint he did.
When I met my surgeon, he gave me my options, and didn't try to make the choice for me. He also let me know that *if* I did have an autoinflammatory or autoimmune issue (which he wasn't comfortable ruling out due to my poly arthritic joints, young age, and other symptoms), a partial replacement was contraindicated, as I'd likely have to have it revised in about 5 years or so. He also pointed out an area on my lateral meniscus that was already bulging, and said that was something to consider. He armed me with a lot of knowledge and left it for me to decide partial vs total.
So I think you CAN end up with a good surgeon even if knees aren't their specialty - but the vetting process is key. Had I not met people who had their knees done by him, I might not have chosen this gentleman.
You can also end up with a good knee specialist who doesn't take into account your entire medical history. Had I gone with the specialist here, I would have ended up with a partial, and may have had it revised early. Then again, it may have been fine. But that he dismissed the other parts of my medical history did not make me comfortable.
And with the surgeon I chose, he knew my goal was to get to hiking and biking again - and chose a knee implant appropriate for my goals.
Of course, I live in a small area with only one hospital. And I think 95% of the time, the specialist will be a great choice. But every once in a while, you can find a non-specialist who will do a great job, and *might* view his patient as more than an x ray or MRI. And that, to me, was invaluable.
After my TKR, (Ironically) a friend who referred me to him (she had a TKR, also) went to him for a hip issue. He referred her to someone else, as he said the two things he does NOT do are hips and spine, as he doesn't feel that he does a great job in those areas. That confirmed to me that I had the right guy!
