Young patients had ‘marked improvement’ in most subjective outcomes after THA
Results presented at the American Association of Hip and Knee Surgeons Annual Meeting showed major improvements in most patient-reported outcomes at 10-year follow-up among young patients who underwent total hip arthroplasty.
John C. Clohisy, MD, and colleagues reviewed patient demographics, patient-reported outcomes, polyethylene wear, reoperations, failures and survivorship over time among 168 hips in patients younger than 30 years old who underwent THA with a highly crosslinked polyethylene bearing surface.
At a minimum of 8 years, 83% of hips were available for follow-up, according to Clohisy.
“We showed marked improvement in the patient-reported outcomes, except for the SF-12 mental score,” Clohisy said in his presentation.
Clohisy noted 4.2% of hips underwent revision, four for aseptic failure and two for periprosthetic joint infection. He added six patients died prior to the minimum 8-year follow-up.
“Like other groups in other study populations, we showed marked improvements in wear compared to conventional polyethylene, with a linear wear rate of 0.014,” Clohisy said.
Clohisy noted patients had a 97.2% survivorship at 10.5 years. In terms of complications, four patients had aseptic failures, one patient had acetabular loosening, one patient had liner dissociation and two patients had infection, according to Clohisy. He added two patients had heterotopic bone excisions and one patient had superficial hematoma, all of which required surgery.
“These results are encouraging and support total hip arthroplasty in the very young patient,” Clohisy said. “Obviously, we need longer-term data and more information about failure mechanisms as we get into the second and third decades.”
