I've done some reflection on this since last posting.
Since your GP has already done the referral, you could contact the GP's and ask which hospital the referral was made to. Once this is known, you can contact the orthopaedic department for further info (including the expected waiting list time). Google the names of the surgeons in the department and see what comes up.
Also, you could join local special interest groups, they will be a gold mine of information.
