My husband has had knee problems for 20 years and had x-ray done back then advising him that he had bone on bone arthritis and would need a knee replacement. He didn't fancy that and has been surviving on masses of pain killers since then. He is 68 and retired now and a year ago he decided to do something about it. Saw GP, had x-ray, was put on waiting list for knee replacement, told waiting list was 4 years. Out of the blue a letter arrived from hospital last Friday telling him he had an appointment with consultant at 7.40 pm today. He is just back from the appointment and the consultant just tried to persuade him not to get knee replacement and to come off waiting list. Is this what they are doing now to get waiting list down? We are in Scotland.
