I’m the outlier who had posterior surgery although it’s really done from the side. It was a miracle surgery for me. My hip never hurt, it was all referred pain in my leg and thought it was from my back issues. It was excruciating to walk before the surgery. Zero pain after and I went home the same day. My surgery went great, I was off tramadol in 3 days. I actually sought a doctor who did posterior surgery. I had my reasons. I made sure to choose a doc who had an excellent reputation. The big deal with posterior surgery is just not to bend forward deeply for 8-12 weeks…I was allowed per my PT after 10 weeks. My right hip is now jealous of my bionic left hip. I do chair yoga and I have a lot more flexibility with my bionic hip. If my right hip ever gets to where it needs to be replaced I hope that my surgeon is still doing them and I won’t hesitate to have him replace my other hip as well. I think the key is getting a good surgeon but all our bodies are different and what my experience was, may not be your experience. Oh, and hip replacement is simpler than knee replacement. A good set of YouTube videos to watch on hip replacement is the Canadian “Talking With Docs.” Look for their videos on hip replacement. They are two Canadian orthopedic surgeons and I watched all their videos and was completely prepared for my surgery. I live in the US, but I subscribe to their channel and they have practical videos on all manner of medical subjects.
