Scar tissue post hip replacement

Hello, I've had two THR on my right side and one on my left. I feel like someone mentioned something about scar tissue being a possible cause but can't find the post. Does anyone have any information on pain from scar tissue? It seems like since I had two incisions it's a possibility. I've gone down so many rabbit holes trying to figure this out and am hoping maybe I've found a cause? I am seeing there's no imaging that can be done to see scar tissue so I'm curious how it was diagnosed? HELP!
