Like I said in my Researching Your Knee Replacement (Part 1, Part 2, Part 3), it helps to research and ask questions. I started like I did with the knees, looking on YouTube and other webpages. But of course, I went back over to Booktoots' Healing blog, but if she had something on that, I may have missed it. However, Robin's site had some info.
After much research, I knew that there were two approaches to this procedure, the anterior and the posterior. What sealed it for me in getting the anterior approach over the posterior was an article in the Washington Post. As it turns out, it was one of the referrals my rheumatologist gave me, and was also mentioned in the article. I made an appointment with one doctor there. Then when I saw him, we talked about the surgery and I asked him if he does the anterior approach. He didn't, but he passed me along that same day to another doctor who did, and from there I had my surgery date.
About three weeks before the surgery date, I went to the hospital for presurgical testing and met up with a case manager and a physical therapist. I was cleared for surgery. Later that evening, I had a "joint class," meaning they cover what I'm to expect before and after surgery. I was the only person in the class.
It was difficult enough after the first knee surgery when the surgeon had to cut the muscle due to the muscle contractures I had, but after seeing the laundry list of restrictions in effect for 6 weeks...
The surgeon who did the knees does the posterior approach. My surgery date with him was cancelled and went with the current surgeon.
