"Waiting for knee surgery"

Been to the community before post op for my left knee op, the community physio and so I was wondering where I need to go to get a referral. The specialist said I can do pre-op so I’m waiting on operation for my right knee. I’m waiting a bit and my knee is getting worse, I think the hydro is the only way to go. I found it very good post op. I haven’t got anything left in the cartilage, but it’s hard to get in to elective surgery. I’m just waiting on a date to come through. I think the surgeon was being a bit optimistic when he said before the new year. I haven’t received anything about it.
