Cheers Casper and everyone else for the good will. If I have one criticism of my experience with the NHS it is that this operation should have been done and dusted last year. Around 18 months ago I was having horrendous problems with my left knee, awful pain and swelling which was happening more frequently. So the decision was made by the consultant surgeon to replace the knee.
Once you're on the waiting list it shouldn't be more than 14 weeks before they operate. I had my pre op assessment which flagged up sleep apnoea, which I had no idea I had, but that delayed everything as I had to partake sleep studies. The process of waiting for appointments with this department, getting issued with treatment (CPAP machine in my case) then waiting for results and further consultation was long and drawn out. So much so that I disappeared off the waiting list for the knee op without knowing, without anyone knowing.
I brought it up with my rheumatology consultant earlier this year (Dr Fawthrop. she is brilliant BTW) and she instantly got the ball rolling again.
So Casper, if you have to undergo sleep studies when you get on the waiting list, my tip to you is don't let orthopaedics lose track of you. And make sure the sleep studies department pass on your results to the appropriate departments as soon as they can.
Also I've been told 3 to 6 weeks before you can drive, depending on your movement and recovery. Good luck pal.
