That makes sense, probably uneven picture around the country. Either way, I recommend Jacob get on the waiting list as soon as possible, hips only deteriorate. There comes a point where the synovial fluid starts to soften the bone and it chips and it become difficult to walk. An x-ray should show how bad it is.
I have to say my visit to the local hip ward was like visiting gods waiting room. I was the youngest by far so not that surprised by your daughters comment, its an operation dominated by the elderly - and a successful one at that. In no time we were walking up and down the corridors.
Maybe we have some more bills flowing in for mum. it was all done in a terrible rush over so I could be in for a another bill from the family, my brother just handed them his CC, it was bit like talking to the undertaker, you just hand over the money in an emotional state.
