Raylo, you've come to the right place....Yours is a typical progression type story. I as well as so many others on this site feel your pain!! You may not have the worst hip your doctor has ever seen, there's always someone worse off than you, but from your vantage point it's pretty bad. When it alters your life's routine I feel it's time. Only you know the answer. Unfortunately, we men are a stubborn bunch. I waited a year too long and I can't get it back. Put up with it for 3 long years. When you run out of ways to bluff your way through it and people comment on your limp and call you gimp, It's Time!! Why would you get a THA rather than a HRA unless medically necessary? I can't come up with a reason. That being said, you need to do your homework, as it appears you've started to do, and choose a qualified surgeon with the help of this site and any interviews with them that you can. In spite of the press, recent actions by Smith & Nephew, and comments by skeptical doctors who perhaps have an agenda, HRA is the "sliced bread" of corrective osteoarthritis of the hip right now. There will be improvements. You can count on it. But we are lucky to have this technology available today and to be informed enough with the help of others on this site, so as to make a good decision.
Best of luck and absorb as much as you can.
