Attune Tibia issue

If I am not mistaken, if a doc wants to augment or put a stem on a tibia to revise those tibias he has to pull off a well fixed femur and switch to TC3

 

True...where is the letter to the FDA or survivorsip data suggesting the problem?

 

Ask the Colorado reps, then Minnesota, then Kansas and so on

 

did you really ask for survivorship data? There is none, nothing to publish but loose failed tibias.

 

i have heard of tibia issues, but can't figure out why there would be any difference with other tibias, DePuy or others...nothing out of the ordinary with design. Is it stress cause by awesome gradius?

 

Wrong.

 

I would love to add to my collection. I have 5 pics from 2 locations.
All looking like they just came out of the box!

 

Please clarify then

 

Tibial Tray Thickness Significantly Increases Medial Tibial Bone Resorption in Cobalt–Chromium Total Knee Arthroplasty Implants
Matin Et Al, JOA 2016

"Mean medial tibial bone loss was significantly higher in the thick tray cohort (1.07 vs 0.16 mm; P = .0001). In addition, there were significantly more patients with medial tibial bone loss in the thick tray group (Attune) compared with the thin tray group (Triathlon) (44% vs 10%, P = .0002). Despite these differences, there were no statistically significant differences in range of motion, knee society score, complications, or revision surgeries performed."

 

Great response. It is so easy to prove what a shit implant Attune is, and what idiots they have for reps across the country. This is an entry level company now days.

 

I am assuming we are talking about the RP Attunes? Haven't seen the Attunes fail, but sure saw a lot of Sigma RP tibias fail. Surgeons blamed it on the cement.

 

Cementing technique is critical. It does not help that the tray is handled with fatty fingers. Best tecnique I have seen is make sure the tibia bone interface is dry, then put a thick wad of cement on the tibia then with clean dry clove pressurise the cone area. On the tibial component put a thin layer of cement directly on the tibia thus protecting the implant cement interface. Lasly place the tibia in place and whack it. I should get commission for this free advise. So much time is being put into implant design but no one on this forum is discussing cementing techniques...weird. Anyway greetings from Africa.

 

This is some of the best technical advice I have seen on cafepharma. By the way, are you in Africa. Are you a rep or a Dr?

 

I am a rep, and yes from Africa.

 

They teach proper cement techniques to reps on the 2nd day of training. No commission for that advice, sorry.

 

Great, just a pitty you don't teach it to the surgeons.

 

In an interview , I was told it was due to poor keel punches that were not giving a large enough cement mantle. That was 6 months ago. I am still with my company and I am still seeing them fall out and docs having to remove healthy well fixed femurs because they had to revise tibia

Attune update:

337,000+ implanted Worldwide

195 Attune tibial components revised due to Aseptic loosening (.000578)

Of those 195, 50% had BMI >35
