THA survivorship with highly crosslinked liners was 93% at 15 years among young patients

THA survivorship with highly crosslinked liners was 93% at 15 years among young patients

Data presented at the American Association of Hip and Knee Surgeons Annual Meeting showed total hip arthroplasty performed with a highly crosslinked acetabular liner in patients younger than 50 years of age was associated with Kaplan-Meier overall survivorship of 93% at 15 years when revision due to failure was the endpoint.

“The non-highly crosslinked group showed 87% [survivorship]. This was significantly different,” said Andrew J. Bryan, MD, who presented the results.

Six patients in the group treated with non-highly crosslinked polyethylene and no patients in the group treated with highly crosslinked polyethylene underwent revision surgery, according to Bryan’s presentation.

THA was performed in 273 patients in the study for indications that included osteoarthritis (62%), avascular necrosis (22%) and dysplasia (5%).

“There was no wear in the highly crosslinked group as noted by our method, and there was no osteolysis in the highly crosslinked group,” Bryan said.

The six revisions performed in the non-highly crosslinked polyethylene group (10.5%) were for wear.

According to Bryan, the two groups’ clinical outcomes were similar.

“The use of highly crosslinked polyethylene led to a significant reduction in risk of failure in patients less than 50 years old,” he said. – by Susan M. Rapp
