Sorry to hear of the pain.
I’d recommend you go to a physical therapist to see if there is some muscular imbalance that is getting in the way. The older we get, the more various muscles seem to go to sleep and over time those weak muscles or muscles we don’t use (don’t “activate” in the words of PT works) can cause all kinds of problems. Problems that can seem like device problems.
Can’t guarantee that PT will help but that’s a good place to start. You mention repairs on two gluteus muscles. Did you do PT after those procedures? It’s very typical for those muscles to go to sleep as we age and after surgery. Since you’re athletic, PT’s will love to work with you. I say focus on finding a really smart PT over someone who emphasizes working you hard. You want the smartest most precise exercises, not just hard exercises randomly chosen.
Good luck.
