A client of mine who has a number of surgeons in his family and who is therefore able to get a good view of where to go recently had a hip replacement at Springfield hospital Chelmsford. He had left it too long to have a resurfacing. It has turned out well and he is very pleased. I gather that there may be a pathway to NHS treatment there under the "Book and Choose" system.
