Young patients who underwent total hip arthroplasty were found to be just as active as individuals with similar diseases but healthy hips, according to study results.
Researchers administered the University of California Los Angeles (UCLA) activity score, Hip disability and Osteoarthritis Outcome Score (HOOS), SF-12 version 2 and Functional Comorbidity Index (FCI) questionnaires to 70 patients 30 years old or younger who underwent total hip arthroplasty (THA), 158 general patients 31 years old or older who underwent THA and 106 young, comorbidity-matched patients who had not undergone arthroplasty and had no significant hip disease.
Before and after adjustment for comorbidity, sex and race, results showed similar mean postoperative UCLA activity scores among groups. A negative association between postoperative activity and increases in comorbidity and female sex were found through adjusted analyses, according to the researchers.
The researchers also found that, compared with patients in the general THA group, patients in the young THA group reported higher expectations of postoperative activity. The young THA group also had greater hip symptoms and poorer hip-related quality of life.
Although mental health scores were significantly higher in the general THA group, the researchers found patient groups had similar postoperative SF-12v2 physical health scores.
