Can't advise as dh got his THR done on the NHS at the Jubilee in June. But his experience might reassure you - but there again, every case is different
.
He'd been on the waiting list for 53 weeks and actually had been told by his consultant 2 years before that that technically he needed a hip replacement but as he was still running around refereeing youth rugby he apparently has a very high threshold
, he wasn't going to put him on the list (which my dad, a retired medic, confirmed wasn't just him being fobbed off).
He was transferred to the Jubilee's list in February. There was a slight delay as he needed 3 teeth extracted, and they won't operate until 2 weeks after an extraction.
He was done as Day Surgery - in and out in under 12 hours
. He was a suitable case though - relatively young ("only" 64
) and fit. We were in Madeira in March and we were walking c20,000 steps a day
(he did need his Naproxen though
).
Be aware though that after the physios check that you can walk and climb stairs (which they did with dh within 2 hours of coming out of surgery
), there might not be that much follow up 
Our house (an upper conversion) is on the first floor so he had to climb c20 steps to get to the living floor. We're fortunate though that our main bedroom is on the same floor, as is the main bathroom - and we have a big walk-in shower. So once he was in the house, he didn't have much walking to do (and I was at his beck and call
). The hospital delivered a frame for support for him for the loo.
I did have to drive him to 3 appointments to get his dressing changed - and also to the doctor's practice on his behalf to get a new prescription for the heavy duty opioid painkiller that he'd been given by the hospital and had run out of (he was told not to stint on the painkillers). So you do need to have someone to run around a bit for her.
He's had no additional physio but is expected to do the exercises he was given 3-4 times a day. He's slipped up a bit on this over Christmas but is working on getting back in to the habit.
He gradually increased his walking - initially round the house (with 2 crutches), then outside, gradually getting longer and reducing to one crutch and carrying the other one, then just carrying the two. Within a few months he was not using crutches at all. 7 months later and he walks without a limp.
The hospital was excellent with its telephone support and he can call them at any time with any concerns or questions.
