Hooo boy, how timely.
I had my first hip done in spring of 2018. Non-Robotic, posterior approach technique. Titanium-porous spike with aluminized ceramic femur head. Polycarbonate acetabulum.
Took several months before I was safe to put full body weight onto it. Pretty good recovery, pain-wise. Until I fell on it 9 months post-op. Didn’t do damage to the hardware but damaged ligaments and tendons. It is a source of pain.
The other side will have to be tended at some point. Both of my femur heads are formed as egg-shaped, opposed to roughly spherical. Born that way. I blame my parents. 
By comparison, my wife. She had her left hip replaced on March 5. Robotic surgery. Not anterior, not posterior. A technique that’s basically entering just along the median line of the body. She was off the walker within 3 weeks. Mostly off the cane. Zero pain post-op. 1 night in the hospital, light use of opiates ONLY in hospital. Zero use at home. Managed fine with Tylenol.
This coming Thursday she has her right hip replaced. No reason to think it won’t be just as successful.
8 years and a world of advances. Just remarkable. Both of us are very compliant clients re: P.T. both at home and at P.T. centers. Do ALL of the reps. Hydrate frequently, etc.
Both of us were in Twilight sleep. I remember my surgeon literally using the mallet to pound the implant home. ( That’s all I remember ). She has zero memory of the event.
Both of us used the Hospital For Special Surgery. Pun intended, they are THE cutting-edge bone joint in America. For 16 years in a row, chosen as the #1 place to have Orthopaedic work done. And it shows.
No matter where you’re having it done, ask many questions. Take paper or record the conversations with your Dr on your cell phone or an audio recorder. Surgery is stressful. Don’t assume you will remember things. Best case: bring an advocate. Partner/ Spouse/ Trusted friend etc. Have THEM take many notes. There’s no such thing as a dumb question.
During my initial visit with my guy in 2017, we were working our way through the questions. I was in amazing pain. Had been bone-on-bone for more than a year. At some point I asked the following question:
" Doctor, after the surgery, will I be able to play the violin? "
The guy roared with laughter. I wasn’t wasting our time. I needed to know that the person who held my personal and professional future in his hands wasn’t a crab. A stiff. An old-school dour jerk. I needed to know he had a bit of light to him. His response put me at ease. It mattered.
EVERYTHING matters. It’s your body.
A note about bone-on-bone pain. It greatly affects mental health. I’ve had to deal with chronic deep pain since 2000 when I fell and broke my L-3 wide open. So, I get what chronic pain is. The hip pain eventually became a dominant element of my life. Waking it was the thing that limited how many steps I had per day. It ruined a night’s sleep.
Don’t delay. A bad hip won’t get better through PT. It won’t slowly heal up. It will just decline and cause you more agony.
My two cents !
ETA: Wife and I both also had spinal blocks additional to twilight.
