My dad is getting an implant next month just wondering which is better, ceramic or metal?
check the sidewall of the tire and inflate it accordingly.
Hard to tell because there's no such thing as one size fits all. Choosing between ceramic and metal hip units depends on many factors. For example, my dad chose ceramic to ceramic because it has the best wear rates, that is, based on his research. However, there's an issue with ceramics getting noticed today, such as the squeaking sound over the years of usage. (see link below). Anyway, I suggest you list down all your questions and discuss it with your doctor including the cost, especially if you're paying for the surgery yourself. Good luck.
