title: Influence of self-reported limb length discrepancy on function and satisfaction 6 years after total hip replacement.
abstract: OBJECTIVE
  Limb length discrepancy (LLD), a complication of total hip replacement (THR), can lead to limp, nerve injuries, functional limitations, and dissatisfaction. To assess the influence of perceived LLD on function and satisfaction 6 years after primary THR.
  
  
  METHODS
  Survey data from 638 Medicare participants aged 65 years and older who underwent elective primary unilateral THR. Questionnaires included demographics, comorbidity, pain, function, satisfaction, and perceived LLD. Primary outcomes were function and satisfaction at 6 years. Wilcoxon tests determined associations between perceived LLD and function and satisfaction. Logistic regression identified the independent effect of LLD on worse functional status and dissatisfaction with surgery.
  
  
  RESULTS
  Adjusting for demographic factors, education, and comorbidities, patients reporting perceived LLD were twice as likely to report poor functional status (odds ratio [OR], 2.00; 95% confidence interval [CI], 1.19-3.36). Multivariate analysis-revealed perceived LLD was a significant correlate of dissatisfaction with surgery (OR, 2.24; 95% CI, 1.40-3.70).
  
  
  CONCLUSIONS
  Perceived LLD is a significant correlate of poor physical function and dissatisfaction 6 years after THR.
