Has anyone had a "button" put under their kneecap during or after a TKR?

Edited , 7 users are following.

I saw my surgeon yesterday for my almost one year check up. He says my kneecap is not sitting correctly and causing rubbing and pain in my knee. He wants to see me again in 6 months and if it's still not right or is any worse, wants to put a "plastic button-like device" under my kneecap to prevent it rubbing and causing pain. Has anyone else had this done? I'm in Australia...he says they often do this in U.S.A. as part of the original surgery. He also told me that this added surgery can not be guaranteed to correct the problem or stop the pain!! Any advice would be appreciated. Thanks.

    Yes, I have a button under my kneecap, I do not have any problem with my knee at all.

    I live in U.K and apparently suffer with similar problem because the last doctor I saw in August seemed to think because my kneecap was not sitting correctly I would need to have it removed and a prosthetic one fitted. He commented this happened in 2% of TKR's.

    I had my TKR in Feb 2016 and am awaiting my final appointment with the surgeon which will be next week. I will mention this button idea with him because I really would like to keep my kneecap- no more prosthetics for me!! Will keep you posted.

      Hi Mary. Yes I understand what you mean!! Apparently, my kneecap has not been affected by my arthritis....that's why they left it there. But this "patella button" is common practise in the U.S as I said earlier...according to my surgeon. I can imagine nothing worse than having them open my knee scar up again just to put this little thing in there!! My thoughts at this time are...if it causes me no more pain and also is causing no damage to anything in there, I'll live with it the way it is. I'll be interested to hear what your surgeon says about your situation. Good luck with it.    Shan

      I keep hearing about this 'button'

      Can you tell me what it involves and why you needed it.

      I have pain but I also can't walk very well.

      I had a TKR on the 13th Feb 2016

      A nightmare year!

      I'm seeing the surgeon next week plus an x-ray

      I feel he will just move the goalposts again and say it can take 18months etc

      I wouldn't mind if I was making progress but I seem to go back it forward in my recovery

    I had this done on the 15th January this year 2018 and so far there’s been a noticeable difference in my walking.

    However, pain is still waking me up but it could be wound pain as he had to open up the knee again but exactly on the same line as before. Had TKR in Feb 2016.

    I spent nearly two years in agony and unable to walk 

    Some days I want my old knee back. Nothing was as bad as all this. It’s affected the whole of my body.

    However, he did say success was 50/50 so I will keep you posted

    Hi, I had my left TKR in August 2016 and the following March my right knee which has not caused me any problems gave up on me. I underwent a right TKR in June 2016 and my kneecap was so badly damaged and had a deep channel gouged out of it it couldn’t be fully resurfaced as that would have made it too thin and would have shattered. My surgeon resurfaced as much as he could and then inserted the patella button at the same time as the TKR. I’ve had no problems or issues, recovery from both knees has been very similar. I was told kneeling would be more painful on that side but it hasn’t been. Both operations were on the NHS in the UK and done as day cases at my request. I can’t speak highly enough of my surgeon and as already said, the button has been fine. Good luck for the future.

    hi,

    please see previous post from me, I had a patella button inserted as part of my second total knee replacement as my patella was so badly worn it was at risk of splitting in half. The button helps to strengthen it and Ive never looked back. No noticeable difference from my other knee replacement and it was done on the NHS in the UK, both my knee replacements were done as day cases at my request with a fantastic surgeon that I couldn't recommend highly enough.
