Outcomes Are Encouraging for Total Hip

Arthroplasty Patients Under Age 30

For Immediate Release
November 7, 2020

Dallas –A presentation at the 30th AAHKS Annual Meeting reported on a study on contemporary total hip arthroplasty (THA) with highly cross-linked polyethylene (HXLPE) for patients under the age of 30, which is a controversial, yet increasingly performed procedure. As the surgery prevalence increases there is a need for more data on this population to inform decision making between patient and surgeon.

The research team investigated implant survivorship, PROs and polyethylene wear rates through a retrospective review of prospective data. 140 patients that underwent primary THA with a HXLPE liner were reviewed at a mean of 10.6 years follow-up. Patients ranged from 11-30 years (average, 22) old at time of surgery using various patient-reported outcomes scores.

Lead author, John C. Clohisy, MD, and co-authors, Christopher A. Anthony, MD, Wahid Abu-Amer, MD, Serena Freiman, MD, and Gail Pashos, BS, found that at the 10-year review 95.8% of the THAs survived and 4.2% had been revised. Those that had been revised were for instability, infection, aseptic loosening, and liner disassociation.

The study concluded that “THA with a HXLPE bearing surface performed in very young patients, those under the age of 30, has a 96% survivorship at 10-year follow-up. Marked improvements in pain, function and activity, combined with low failure and polyethylene wear rates strongly support THA in very young patients with disabling hip disease.”
