Slight overhang of femoral component

Hi all, received my discharge lette to GP today and it said I have the above.  Does anyone know what this means?

Best thing to do is put the subject in the 'search' box on the PATIENT page. You will get the official NHS answer.  Best wishes.

I did Margaret but isn't telling me anything.

Ring your surgeon's secretary and ask if you can find out what it means? Good luck!

It's made me cross because when I saw him there was no mention of this at all.

Sometimes I feel medics treat you as if you are dumb and ignorant! And talk over your head to your gp etc. I would still ring and ask for an explanation- its your body!

Ask for a 2nd opinion through your GP

Isn't this something similar to what Veronica was told??? this what I saw on internet. . quite common apparently . . .

Overhang of >or=3 mm occurred in at least one zone among 40% (seventy-one) of 176 knees in men and 68% (177) of 261 knees in women, most frequently in lateral zones 2 (anterior-distal) and 3 (distal). Female sex, shorter height, and larger femoral component size were highly predictive of greater overhang in multivariate models. Femoral component overhang of >or=3 mm in at least one zone was associated with an almost twofold increased risk of knee pain more severe than occasional or mild at two years after surgery (odds ratio, 1.9; 95% confidence interva

Yes - this is exactly what I have - but 6mm (which they told me is at the top level of acceptance - huh, I'd like to see the man who did it walk around with a 6mm overhang!) Interesting to see it states 3mm in your post! I thought mine was across the middle of the knee, as that is where most of the pain is, but I found out yesterday it is on the right side, where the 3 large lumps have formed. Blessed thing is driving me insane with pain today. The surgeon yesterday said it was the biggest reason for early revisions.

Yes but what does this  mean???  I saw that myself and want to know in layman's terms what this means.   I find it ridiculous that this wasn't mentioned to me.

When did you have your knee done?   I'm six months down the line.  I have tightness still and after walking quite far knee swells and is sore.   I have found night time painful just recently that I didn't get before.   I find it worrying that that kind of stuff happens snd you aren't tokd about it.   Surgeon just said everything was fine at consultation!

My 1st surgeon said the same, but I was in so much pain,he said " if I send you for an ultrasound, will that put your mind at rest". The radiologist is the one who measured the overhang, & put it in writing to the 1st consultant. It was there in black & white. Thats when he kept saying 6mm was acceptable, & my body would get used to it in 2 years. It was at this stage I asked my GP to refer me to a different consultant. Mine was done on 27th October 2014. I have had to change hospitals, & I am so glad I made the fuss, as the new consultant is so very reassuring. Bearing in mind the cost of revisions, the NHS wouldn't consider it if it wasn't necessary - my GP has actually phoned me to apologise for the length of time I've been in pain (& the length of time I will be on a waiting list to have the revision!). Wish I'd had a crystal ball, I would never ever have gone through the 1st operation.

BTW, - I can't walk more than 100 yards still before the pain gets unbearable. Night times are hell - I spend most of them clearing our cupboards so I don't wake my husband. You can't even toss & turn as the leg is like a lump of lead!

I have to say I can walk distances that. Couldn't before, flexion he said as 95.   You must be in so much pain.   I am not that bad, hoe it doesn't get worse though.   My knee I can't feel anything as still very numb.  It's quite shocking what they don't tl you.   There is a company That make knees to measure individually but only done privately at a cost of £10,500,   Not nhs of course!!!

Well, you had me curious. From what I can see, the femoral component is part of the knee replacement. And sometimes people fall in the middle of two sizes and the doctor has to decide if you need the one that will have an overhang or and underhang. It would be good for you to talk to your doctor and ask for some more details and ask hoe that will impact you.

 

Thank you for that.  

I think it means that the two parts of the prosthesis don't perfectly fit together, but that there is a slight overhang . .which can cause impingement on the soft tissue and subsequently pain . . but as you can see from the article, about 40 per cent have some minimal overhang, and in your case, it may not cause any problems at all, and may be a very tiny overhang. . .  . . However, that is just how I am reading it from several sources, but I may have it all wrong. I was looking for possible causes of the sharp pain I get when bending the knee, together with a sort of click . . . mine sounds a bit like impingement . . . . hope not!

Was it like that right from the start Veronica?  I'm worrying a bit about mine.  At six weeks I was walking well, up to about 14 weeks. . but from then on it's got steadily worse, with a sort of nipping pain every time I bend, as if it was being pinched sharply.  I'm beginning to go back to the straight leg walk, although I know it's a mistake, but permanent pain makes walking no fun as I am sure you know much better than I do!  I don't really want to go back to the surgeon, because if there is something wrong, I'm not having it opened up again. It is obviously nowhere near as bad as yours!

Not from the start - very painful, which shocked me - but I had to have 2 weeks bed rest because of a huge heamatoma down the whole of the operated leg (which my GP likened to being run over by a double decker bus) - so when I finally got up & moving, I put all my extra pain & stiffness down to being behind everybody else. At about 9 weeks, I started to query it, & had an excellent female physio, who nagged me to ring the hospital up & be seen. It's from that time when it all fell into place. I had to wait for the apointment, then the ultrasound apointment, then the apointment to discuss the ultrasound, then the 2nd opinion one, who ordered a full leg alignment x-ray, then wait to see him to discuss those results, & the weeks have dragged on. I have come to terms with having it done again. I have re-read the 4 part A4 papers I signed, & it quite clearly says some fail for various reasons, 1-2%, so someone has to fall into that catergory & sadly, I'm one of them. They really do like you to try & live with it, & that is the fight I have put up - so much pain, stiffness & a life turned on it's head, I simply want at least the chance to try again with a revision. Luckily the new man has said it HAS to be done again, so no more fighting, just waiting. At least I know what lies ahead, which is more than I did first time around! If you really are concerned, then you must go & be seen. We hopefully have a lot more years ahead, & they should be good years, not bad ones! - Veronica

thanks Veronica. . .it's just that I was walking so well, and now the pain is constant every time I bend the knee. . but not when sitting or lying down.  I'll give  it a couple of months, and see if it's just one of those up and down things. . .Statistics do seem to vary a lot. On another page, I saw that about 20 per cent of people have moderate to severe pain two years after TKR,  . . quite a lot more than the 1 - 2 per cent your form said!  Sounds as if your first surgeon was a bit of butcher, with that hematoma!  Strangely, I never had any bruising at all . . although quite a lot of nerve damage and pain . . oh yes, just a bit of bruise on the ankle.  Every knee op seems to be different!
