I was just wondering about any gneder issues with the OtisMed. As a woman of 50+ yrs. who was in need of bilateral knee replacements for years now, I have seen videos of tradiational and OtisMed surgery and have found the OtisMed surgery far more aceptable and less brutal to the surrounding bone, but my impression was that the custom part ends with the bone cut for the prosthesis. The prosthesis, however, is not necessarily customized and therefore may not account for gender differences, or for that matter, minor individual differences. Am I wrong about this? Can anyone who really is knowledgeable on this procedure answer this question without bias, please?
if your surgeon is using the triathlon knee it is gender specific in that the size ranges are #1 through #8 the smaller sizes being fit for women and larger sizes for men. thats not to say if you are a large boned woman or small boned man the implants wont fit, they still make the geometric cuts with size specific cutting blocks so they will fit anyone.

<quoted text> I can see you didn't look at the OTISMED TO THOSE OF STRYKER DEVICE. It's lot smaller for either gender my friend and it's not the size of your hand all metal. OtisMed is mostly plastic with a disolving metal screw and your body works well with plastic then any metal. If you look in the land field everyone knows plastic doesn't desolve which they say is a problem. In time metal will break down but maybe not in your life time but the simple fact is metal won't feel natural like the plastic will. People who like uncustom fit with knees replacement that suppose fit everyone alike I say stay in line and get them. I'll go where the custom fit is for me and the heated plastic warm from my body will make it feel natural. The strength is just a strong as any metal. J. Nixon
the otismed is not an implant in itself it is a technique used to put in the stryker knee, all the large ortho companys are coming out with their own version of the otis med to put intheir existing knee implants. you still have a metal femur amd tibial base the plastic is sandwiched in between the two.

I read all the posts to date and it seems that on posts have done follow up to the bilateral guys surgery. Wondering how he did?
Is this otis med a procedure? What about the stryker? Did this doctor use the triathelon knee in that guy?
My husband is getting close to needing a new knee and we are trying to research the options for him. He had one knee done 7 years ago and is doing fine on that one. Now the other knee needs to be replaced.

Here's a quick OtisMed update.

To date, about 15,000 total knees have been implanted using OtisKnee custom blocks. About 10,000 are Stryker's Triathlon implants, and 5,000 are Biomet's Vanguard implants.

Biomet has released into the market their own version of the OtisMed blocks, to work with their Vanguard system.

Smith & Nephew has also released their version of the technology, to be used with their Genesis II implants.

Zimmer is telling customers that they have just released their version of the OtisMed technology, but I don't know anyone who has seen it in the market yet.

Wright Medical has just released their version of OtisMed technology, to be used with their implants.

DePuy (Johnson & Johnson) is telling customers they are working on their version of the technology, and it should be out later this year in certain markets.

Stryker is looking to either acquire or develop this technology, but is not talking publicly about it.

So, obviously all the major orthopedic companies are moving quickly to grab a piece of the custom cutting block market for knees. The OtisMed phenomenon, now 2 years into it, has burst onto the scene like nothing else in a generation for total knee replacement. That's why all these succesful firms are literally pouring millions of dollars into developing it themselves, because they have to be able to play in that space.

It's great news, since with new investment and research/development will come additional improvements and refinements making it even better as time goes on.

You obviously have not done your research on OTIS. It acts to restore your knee to prearthritic condition using splining technology not mechanical axis like traditional tka. Not everyone's knee is made to be straight. This

Ed B,
You are wrong...even though they claim that they realign the knee, they do not resore the mechanical axis of the leg. This would require an MRI from Hip to ankle. You need to read a chapter on this to understand, but trust me, the otismed knee does not pay any attention to mechanical alignment.

I need total knee joint replacement surgery on both knees. On doing my homework I came accross the Custom Fit Knee and thought how fortunate to have this cutting edge technology..I live in Palm Desert Ca. and have Eisenhower hospital and the best orthopedic surgeons..none of them do or know about OtisMed imaging..one does Makoplasty..
Now that I have read these posts I am very disappointed but thanks to some brilliant men who took their time to post the truth..I am better informed..Thank you..But what is the best way to go?? Theres the Stryker..the Oxford..The Zimmer..what is your take on the Stryker Navigation System??..computer assisted surgery?? I like Jointman...he's got a handle on facts!!
I need help..Thanks

My Dad in Lexington, KY had the Otis total knee replacement May 4th. He's 68 years old and is a very stubborn, independent man and seldom wants "pity" from others. He didn't even tell me or my sister - or any of his family that he was having the surgery. He took a taxi to and from the hospital. His surgery was Monday and he was released to the "taxi" on Wednesday and home.

He worked on a farm most all his life..... for the past 30 years he's painted houses. He's never had a "desk job"...... is is in overall good health.

His surgery was done at St. Joe East, doctors name is John Balthrop (view profile at http://www.bluegrassortho.com/index.cfm/fusea... )

Daddy eventually told us about the surgery - and I was scheduled to visit him around May 24th. He had PT 3 times a week.... he is now walking without a cane/walker and seems to be doing great. He currently goes into the hospital twice a week to do therapy there and continues to do his own excerises and therapy at home. He went into the surgery with a positive attitude and thus far, it seems to be working for him.

I'm no doctor - nor do I work for Otis - but I thought I would post his good results for others to read. I believe with any surgery we all should read, ask questions, research. THEN read, ask questions and research again and again and again.

If it is true like some say that we won't know "full results" until 7 years..... so be it. I'm just thankful my Dad had it done now and is able to walk with no pain.

Best of luck to others.

I agree wholeheartedly with Bilateral. I'm a woman who knows how to access the internet, and I also have a bit of a technical mind. I'm about to undergo OtisMed TKR, and, again, I agree 100% with everything Bilateral has said. I find it offensive that one would be accused of being a Dr. masquerading as a patient just because they happen to know some details about a procedure they are about to undergo. Any patient with an ounce of sense would want to know all they can about it. Hello, Joint Man? It's the 21st Century and the country is not full of a bunch of easily led morons.

Bilateral John...to trust a new technology, and let a surgeon (who has only done 15 of them) do this to you is outright stupidity. Congratulations, you are now officially part of an unmonitored human experiment.

OK, I have been reading about some of the complaints & problems but some of them are a year old or so now. SO WHAT CAUSED THE PROBLEM? Lew from WA, your knee loosened up and was clicking? It's been a year, what was the problem?
Some of the complaints were not followed up with the resolution to the problem. I really would like to know because I am going to have both knees replaced one at a time and I would like to know what to watch for. Thank you for any further info you can supply.

I had my Otis TKR 11/18/08 and my knee (left) is still swollen/very tight and when walking it feels like my left leg is now longer. Is that because it's swollen or is it something else?
Also I still have some pain and frequently makes noise when I walk. I do have about 110 degree range of motion. Is this all normal?
My doctor keeps saying to wait at least a year before another evaluation.
Any advice? Should I see another doctor to evaluate the results?

Its funny that Bilateral John is a patient who knows all this Ortho specific information...like a AAOS link and presentation name. My guess is he isn't a patient.
Some of us patients do research, ask questions, and actually pay attentsion. Your reaction to John is typical of the "I know Best" doctor. on the other hand, after failed Athro surgery, I had one Otho doc ask me what I thought they should do - being the smart ass patient, I said just cut it off - then I wouldn't have the pain -

The problem is no one knows what is "best" onlt time will tell and that is why I've been in pain and waiting 10 yrs till you docs get your S67T togeather.

I had a TKR with Otis Knee in November 2008. The good news was that I experienced no pain after the surgery. The bad news is that my patella is severly dislocated when I bend my knee. This was very noticablee as soon as I started to bend my knee. A frontal xray of my leg indicated that the upper part of the prothesis is rotated (so much so it is obvious from the xray). My new Doctor adises that he is no longer using the Otis Knee procedure and that there is recent data that indicates that it does not work well for someone with my anatomy (large legs with strong outside muscle and weaker inside). Bottom line is they want to take it out and start over again.

i got a otismed tkr in 7/o8 and a revision 6/09 to put in a larger bearing and new patella. i have cracking, grinding, side to side movement that clunks at 30degrees, and instability, can not put any weight on it in a bend it causes alot of pain. xrays show nothing. bone scan show alittle tibia loosening but not in surgery. after the revision it is still doing it. i was told by a chiropractor that i have a strong outer muscle compared to my vmo. my os never told me this and i didn't realize that this could be a problem. could you tell me more on that issue? and what will putting in a whole new one do to change that? let me know because i think i need to look for a new surgeon, because mine is out of solutions. please help.

FDA just asked Otismed to stop manufacturing the otismed knee. They have to apply for a higher level of approval.

Also, many new papers in the last months showing that mechanical alignment is related to the revision rate.

Check out the OtisMed site. Look for the surgeons and they are off the site. Go to "find a surgeon" and you cannot. That's because the FDA is making some changes...to put it mildly.

I had a CustomFit bi-lateral done in BrynMawr. Yes, I was up and walking within a day, bypassing most who had traditional knee replacement. I was making wonderful progress at first; BUT, I have had problems from day 1 with my right knee--feeling like a tourniquet was around it. I worked it and got perfect extension and bend to about 118R and 122L. This was done in FEB of 2008--at that time; I would have posted that I was doing good and it was getting better; but it never did. Now, in retrospect, would I do it again? NO! NO, NO! The pain on the right side of my right knee NEVER went away and has gotten worse. My knees hurt unbelievable some days, and I am still on large doses of anti-inflammatories which I thought I'd be done with after the replacements. My left was doing okay, but now, after a year of multiple problems with the right knee, I am experiencing similar problems with the left. It hurts to go up steps, and really hurts to come down steps. The pain is mainly on the outside of the right knee and outside of the left knee when coming down steps. I have had two cortisone injections so far, for "inflammation of the tibial band" -- Let me say, I have NEVER had any "tibial band" problems prior to the replacements! I have been back to the surgeon multiple times, they took x-rays and tell me that everything checks out ok on the x-rays. I can only assume, that like many "docs" posting here--that there is a problem with the 'alignment' of something (I don't know what); but the pain and stiffness are getting worse everyday and now I am going to get a seocond opinion. I was leary of this 'custom made' idea at first; and thought I should do the conventional surgery with Dr. Booth in Phila. as I was thinking of doing. I am SOOOOOOOOOO sorry that I was swayed with quick results and 'custom made'. Perhaps, I would have similar results, who knows, all I know is--yes, I was on my feet quickly, yes, I seemed to make amazing progress with a little irksome thing with my right knee; but "it will get better with time"-- NOW, the quick results I had have been totally negated--and I seem to be going in reverse. It is totally depressing--to think I'm stuck with this pain, OR, the not so much better prospect of have a revision done. I am making an appointment with another doc for a second opinion today.
