@sarah90s Hello, and welcome to Mayo Connect. You are very young to be facing a total hip replacement, so the recommendations you will receive are very different than a "typical" 60-70 year old person.
My hip replacement journey began in my 50's, and I am on my second set which are ceramic to polymer.
I too am a researcher, and as far as I can tell, follow-up studies show there is a 2-5% chance of squeaking, no matter the implant...
There are no hip implants that have no risk of fracture or dislocation (with the latter being more common.) Your weight and how you treat your implant are most important once you have healed. Failures and premature wear are most common in people with high BMI and in those who try to believe the implant is a durable as the original.
Here is what makes the most difference - the very best surgeon you can find, one who does many hips a year, in a surgical center that likewise does many hips and has the latest and best tools for positioning the implant with accuracy. During my first implant, it turned out I needed a pediatric part due to my small size. In another location, this may have led the surgeon to "force" the wrong piece to work, but this was a large metro hospital with a Peds OR as well, so it only took a short delay to find what was needed. Also, a low infection rate - post-surgical infection is your worst enemy!

As for the difference between implants - there are 3 pieces - the femoral stem which is fitted into the femur, the head, and the acetabular cup. The 2 surgeons are recommending different femoral stems, one of which (Corail) is designed specifically for the anterior surgical approach. Do you know which head and cup is recommended?
