Hey Billy
It is still early days from me so I haven't made a choice just yet. I sent out emails to three surgeons (Bose, de Smet and Beaule) and had replies from all three asking for my x-rays. I have since had a reply from de Smet who told me I was a good candidate for CoC.
CoC is more of an unknown, but I am leaning towards it largely for its pedigree. It seems more a new iteration rather than a revolutionary design (which I prefer).
I like the fact it has been developed by the group that made the original BHR and later developed the Adept system (as both are very successful). Surgical experience with Adept will hopefully translate into success with ReCerf.
Looking through the literature ceramic seems to have a good track record with THR (wear pattern, longevity, biocompatibility, less aseptic loosening potentially via less biofilm formation).
CoC side steps metal ion production. But as many here have said, the metal ion issue is not a problem with a good surgeon.
From the surgeon side Koen de Smet has 11000 hip surgeries under his belt. 6000+ are resurfacings and he used Adept for his MoM patients. He's only done a few hundred CoC resurfacings in the last few years, but is happy with the results.
I did find a paper (2005) with a CoC prosthetic that failed within 3 years (The Journal of Arthroplasty 30 (2015) 416-418). This is not the ReCerf CoC prosthetic. It was designed by a different group, but put in by McMinn, a very experienced surgeon. All patients had symptoms by 3 years. Just making the point there are examples of CoC not working. You can see the early failure as a good sign (ReCerf hasn't failed yet and its 2.5 yr in) or a bad one (CoC failed early). Your choice
All that said I still haven't heard from the other surgeons and with covid I am not sure how soon I will. And I don't feel comfortable traveling internationally without a covid vaccination. Luckily I can still do all my activities (although some are cancelled now with the pandemic anyway). So I just keep reading and ruminating. But I find it interesting so it's all good.
Cheers.
