It sounds as though things go as well with "superpath" as anterior, posterior, or other approaches, based on your good reports. One or two published journal articles also indicate acceptable complications rates of 1 to 2 % per year, with "super" approach, similar to other approaches. (https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2800844
If the article doesn't open up for you, you might search on reviews of hip replacement outcomes by approach. )

"Due diligence " is tricky, although all surgeons at accredited hospitals and ambulatory surgeries are undoubtedly monitored and peer reviewed, so that provides some reassurance ( they have to, to stay accredited and paid). I'm not aware of statistics published on success rates by surgeon similar to batting averages in baseball, hopefully all are >98 % per year year! "Caveat emptor" if the hospital is not accredited or pending accreditation, under new management, just emerged from financial troubles, or the information isn't available. Promotions, anecdotes from friends, and internet testimonials (such as ours) might be reassuring and worthwhile, but long standing reputation in the community and accreditation are suggested. If you are really lucky to know a couple of good orthopedic surgeons, ask who they recommend, it might be helpful?!
