Hi - have tried to fill in my info but says I am not authorised. I am 62, in UK, had TKR in 2015. Had poor recovery, mostly due to anaphylactic shock and severe allergic reactions to meds (only AFTER coming home and due to GP advising me to double the dose of Tramadol). It took 2 weeks to get over and during that time I was pretty much out of it and unable to do physio. Now it is four years later and despite lots of physio, hydrotherapy etc., my knee is at ROM about 30/60, always painful. Also need TKR on my other knee which was not good to start with but has taken a beating due to the last 4 years. I have seen a consultant every year and they only say I need a revision but it is not guaranteed to have a better result. However, in the last few months I have had really severe sharp pains, a feeling as if something is ''catching' in the knee and my limited mobility has been reduced even further. Went to consultant who specialises in revisions and he says I should have the revision. He said my knee is unstable and xrays showed the patella is not in the right place. He says the outcome should be good. I do know that it is a longer and more complex op than the original one and am very anxious. I know I have no choice as there is nothing else I can do but feel very negative about it. It would be at the same hospital, different surgeon. Anyone had similar fears and how did it work out for you?
