Hello Liesa. I read with interest your post. Firstly, youve had 2 TKR's done, and the first one failed, and now the one you have in now has obviously failed otherwise the OS wouldnt suggest a revision in december. Just the fact that youve had a TKR x 2 is enough to cause your knee-cap to tilt. This is often seen as when they do a TKR they actually remove the knee cap and put a plastic button on the innerside of the kneecap to help it track right, and to help the whole joint to function properly. I think youll find that because they suggest revision again, something has happened as a result of the last surgery that causes your knee cap to tilt. That in itself isnt a big problem, as they can easily align the knee cap again, but in your case I think you will find your hardware is either loose or not sitting as it should, thus the suggestion for another revision. In this new revision they will probably take more care that your knee cap doesnt tilt. I have had 6 TKR's and only got to see a specialist in FAILED TKR's after the 6th had gone wrong. Now I face the fact that in October I am going to have to have all material taken out of my leg and the joint fused permantly stiff, just because I didnt get to a specialist a long time ago.I would urge you, as this is your second or third?, to seek an OS who ONLY does REVISIONS. Its of vital importance they get this right this time, so that you dont have further problems. If you have a husband or a good friend to go with you in the consultation, maybe you will be more aware of exactly what the OS is saying and what he intends to do about it, and to ask the questions you obviously have. Dont let the OS dictate to you what HE wants to do, its time for you to call the shots, otherwise you may regret it. But once again, I would urge you, find a NEW OS. Its seldom those OS's that put the first TKR in that can do revisions well. Its a big thing to have revisions done, because every time they need to put new components in, they need to remove some of the healthy bone tissue, and if you have enough revisions, like me for example, theres none of your own bone left for a evt. new implant to hold on to.
I know you are down now, but it is of vital importance also for your mental state of health to get a knee you can live with that gives little or no pain. Dont expect that now after 2 revisions you'll be like you were before all your troubles started, cos that wont happen, but the crux of the matter here is to make sure you get a joint that can be used to a degree that it doesnt hurt you, and so that you can get on with your life. Dont be afraid of asking doctors questions, they obviously know something theyre not telling you because they dont suggest revisions for the sake of their health. Be brave and face the music!! Thinking of you with love,
