I've had both hips replaced, 1st in 20004 and 2nd in 2014. I was living in France at the time so it may not be the same. The 2nd, whilst not 'keyhole' has left me with a 3" scar instead of a very long one of about a foot. I recovered much faster from the 2nd, which was my left hip. I had full anaesthesia.
My husband and a friend each had theirs done by epidural. He was offered a video link so that he could watch - but declined that one!
Recovery - a lot depends on the physio offered, my advice is to do all the exercises and more if you can. I walked a mile a month later and, once all stitches and drains were out, was pretty mobile - say a week? I walked up the steps to our house from the ambulance which brought me home after 6 or 7 days, can't remember exactly.
Hope this helps. :)
