Its only me again,I have just spoken to secretary of the surgeon who will be performing my TKR,she tells me the type of joint preference they have is the..LCS made by BIO-MET,anybody any thoughts or experience of the afforementioned regards klinger.ps come-on jose give us the gen!

United KingdomI really wouldn't worry about it. Biomet is one of the front runners in joint replacement manufacture and the choice of surgeon is far more crucial than the choice of implant. If you are certain this chap has the experience and the reputation as a skilled practitioner of this particular prosthesis, then have confidence in that. Search for my other (recent) posts on this issue and see what I have said elsewhere.

I have a BioMet knee that was put in October 23rd.
It' the only one my surgeon uses.
I'm very happy with it so far.
I had 115 degrees of flexion the day after surgery and now I'm up to over 125degrees.
I guess their knees have a long track record and they have constantly improved on the models. And if I need a revision in 20 years they would probably still be around so I could get one that fit the same.
I'm only 49 and am hoping it lasts 20 years. By then at around 70 I figure I may have to have it again. I have several patients of my own who have had theirTKR's revised recently and they say their second knee is better that the first! And I have two more ladies going in for revisions.
It's my understanding that in most knee failures it's the tibial component cement that loosens. It makes sense because that would be the site that takes the impact of your weight everytime you are walking or exercising.
My surgeon told me if the plastic wore out he could just replace that or just one of the componenets. But I think if there is a problem with one of the components they just redo the entire thing.

"It's my understanding that in most knee failures it's the tibial component cement that loosens. "
Has the component cement had the same level of refinement as the prosthetic itself ? I'm 47 and going to have a BioMet AGC in about 10 days time. I too hope it lasts 20 years plus and since this replacement has been in the field since 1983 i guess it must be a reliable one......I am quite a sporting fellow and when me knee problems started i managed pain with over the counter drugs and at one stage was way way over the recommended dose for adults.....I then found out by reading the extended exposure to pain killers can cause liver/kidney damage so i got off them as quickly as possible. I now manage pain with excercise and don't take any knee related pain killers at all and haven't for 15 years...I play squash, swim, scuba dive, play Golf, ride a Harley, climb hills, dance 6 hours a week (Ceroc...like rock n roll).....i've given up squash in the last couple of years to "save" my knee for the things i enjoy most...but a recent xray showed the knee of a 70 year old in my leg with mostly bone-on-bone action so time to replace....consultant said surprised you can walk let alone do all the things you do...so the question is one of balance...i am managing the pain to the extent i am surprised when people mention i am limping...i just don't notice any more..... Morning after a dance night or cold mornings i can tell...good weather vain my knee ! ....So what can i expect after TKR ? Do i reset my pain counters ? What do i put up with and what shouldn't i accept ? ......."Every step i take is a considered step" is something i do almost sub-consciously....by that i mean i never put my foot down without considering what i am putting it down on...i don't / can't run any more (hence no squash)...but i dance, lug a full golf bag around a 5 mile golf course and support the weight of my Harley when required (624lbs)..this is pain i manage.........is after TKR any better ? what say you out there my fellow firum readers ? anyone had an AGC by BioMet ?
sincere regards Jon

By which I am supposing you mean, has it been advanced any in design and manufacture?
Well the short answer is, only minimally. The bone cement (methyl methacrylate) manufacture has been slightly refined but since it only acts as a kind of filler between the bone and the metal, it actually doesn't need the continuous upgrading that the prostheses do. The reason the loosening occurs at the bone/cement interface is not to do with the failure of the cement as a product but to do with the bone and the way the cement is applied to it.
(here comes another mini lecture!!!)
Bone put under pressure under cement like this will die back. This is called resorption. Inside the bone (where the marrow is) the hard compact bone changes and becomes a kind of honeycomb. Naturally the spaces in this honeycomb are filled with marrow fat, fatty oil and blood. If the cement is simply applied to the surface of this then during time, the spicules of bone will die back under the loading and the cement will lose it's anchorage. However, if the bony matrix is flushed out with a water jet (like a dentist air or water jet) then the little cavities will be emptied of fluids and permit the bone cement to be forced deep into the matrix. Now two things will happen: 1. the cement will encompass and support the honeycomb of bone and 2) the cement, being deeply embedded, will be firmly anchored in the bone. This is referred to in 'the trade' as cement security.
Failure to give time and care to cleaning the bone and applying sufficient force to the cement, can mean loosening which may take years to develop.
