Kitten701, I certainly hope it goes well for you. I have had bi-lateral hip replacements, (2003,2004). I only had a very small amount of leg length discrepancy, and used a little lift in my one shoe. About 2020, I started having a "clunk" coming from my second replacement. I finally went and saw an orthopedic doctor who was quite sure it was my back? I really didn't have any pain from my back, so I was confused. I ended up seeing about 3 other doctors to consult about my back. OK, I guess I had a lot of degenerative problems and scheduled to have a fusion in 2021. That did nothing to stop the "clunking", so I went and saw the ortho doctor again and we decided it should be replaced. The revision surgery I had resulted in 3 very painful dislocations of my hip. Finally, had another surgery to correct. The doctor told me that because I had the back fusion, (and he thought the cup looked good, so he did not replace that) and as a result, he said that was causing an impingement. I was very disappointed that the surgery ended with about a 1" difference in my leg lengths. My original joint is now about 22 years old, and although it's painful at times, I think I'll be checking out with this one!
