Ankle prosthesis relieves all pain in 72% of patients

More than half of patients resumed sports with Hintegra device.

March 2005

Swizterland flagWASHINGTON — A Swiss and Belgian study of the Hintegra

total ankle prosthesis shows that the device may provide patients with

greater mobility, less pain and, in many cases, a return to sports.

Of the 134 consecutive ankles examined, 72% of patients said that they

were pain-free after operation. Similarly, researchers reported that 82

(61%) participants returned to sports — including swimming, skiing and

hiking – and reported an average clinical 37° range of motion. “The

AOFAS (American Orthopaedic Foot and Ankle Society) hindfoot score has

shown improvement from 39 points up to 86 points significantly,” Victor

Valderrabano, MD, said during his presentation at the American Academy

of Orthopaedic Surgeons 72nd Annual Meeting. Valderrabano is a staff

member of the Kinesiology Research Center and Orthopaedic at the

University of Calgary, Canada, who is on exchange from the University

of Basel, Switzerland.

Surgeons implanted the prosthesis in 128 patients (134 ankles). Most

patients (75%) had posttraumatic osteoarthritis. Other diagnoses

included systematic arthritis (12%) and primary osteoarthritis (13%),

Valderrabano said.

Researchers followed participants for a mean of 2.6 years and measured

surgical outcomes using the Visual Analog Scale (VAS) and fluoroscopy.

Patients reported average VAS scores of 2.6 and 34° of motion.

Patients give good ratings

Most participants gave the implant high ratings, while 14% reported

moderate satisfaction. Researchers found that only 4% of patients were

dissatisfied with the procedure.

Some patients required additional operations. Surgeons performed six

Achilles tendon lengthenings and ligament reconstructions. Patients

also received 26 arthrodesis and eight osteotomies, Valderrabano said.

AAOS WashingtonResearchers also reported 11 revised ankles. According

to Valderrabano, most revisions occurred in early procedures with

post-traumatic clients. Investigators also discovered implant loosening

in eight patients, but Valderrabano said that the findings were “based

on the first design of this ankle, which had at the very beginning a

single layer of coating.”

The latest version of the Hintegra (Newdeal SA) offers a double coating

of porous titanium and hydroxyapatite, a human bone structure. The

Hintegra is anatomically designed: “The talus has a medial radius

smaller than the lateral one on the human bone,” Valderrabano said.

“The total ankle replacement, the Hintegra, is an unconstrained

three-component mobile-bearing prosthesis having a tibial component and

talus component and polyethylene inlay and it’s not cemented,” he said.

Hi a,

Thank you for this article. I have a very bad ankle, and I'm trying

to hold out and not get my ankle fused, I want to wait for better

ankle replacements, and these kindz of encouraging results give me the

strength to wait some more.

Thanks again.

Hey June and a.

Nice not to wait alone.

When I saw an ortho last fall, he said that with RA he thinks

replacement is a far better strategy. But then he said that his

patients who'd had both would probably say they preferred fusion. He

also said that replacement (for me, at least) would require two full

surgeries each with its own healing period. I believe he uses the

STAR treatment. Still, my rheumy suggest I don't hurry, as ankle

replacements aren't quite there yet.

I know in researching all of this I found a site that claimed you

could get a fusion first and then have the ankle replaced later, but

it sounded like a few errors in surgery might make that impossible.

Sigh.

Wait and hobble.

There are other companies out there who are coming out with their own

ankle replacement parts. I spoke with one of my sales reps the other

day about it. His company makes hip and knee joints and are coming out

with an ankle replacement as well. The advantage is that these other

companies are learning from the company who first came out with it. So

they know what was good and what needed work. Give it about a year and

their will be several brands of them. It is my understanding that the

one that is out there now doesn't last very long before you need

another replacement. Soon there will be more choices...Marina
