Predicting Dissatisfaction After Total Hip Arthroplasty: A Study of 850 Patients
Section snippets
Patients and Methods
Institutional review board approval was obtained for this study. We carried out a single-center prospective cohort study of 907 consecutive patients listed for primary THA between 2003 and 2008. Patients were included if they were older than 18 years, undergoing primary THA, and were able to consent to the study. Recruitment was carried out at a consultant-lead preadmission clinic 2 weeks before surgery. At this consultation, detailed data on comorbidity (hypertension, diabetes, ischemic heart
Statistical Analysis
Continuous data were checked for normality with histograms. The Student t test was used to compare parametric continuous data including OHS, SF-12 physical component scores (PCS), SF-12 mental component scores (MCS), and the change in these scores at 12-month assessment. χ2 tests were used to compare data for comorbidities, complications, the surgical approach used, and satisfaction. Potential predictive factors that reached a level of significance where P < .10 after univariate analysis were
Results
A total of 907 consecutive patients who underwent 939 primary THAs were recruited. At 1 year, we were able to review 850 patients (93.7%) who had undergone 882 THAs. These patients formed the study group. There were no statistically significant differences in the preoperative data responses between patients attending for follow-up and those defaulting. The mean patient age was 68.3 years (range, 54-99; SD, 10.4). The primary diagnosis was osteoarthritis for 694 hips (78.7%) and an inflammatory
Discussion
The aims of this study were to determine the incidence of dissatisfaction after THA and to investigate the relationship of dissatisfaction with patient-reported function. This study established an overall incidence of dissatisfaction of 7% 1 year after THA. To our knowledge, these data have not been previously available specifically for THA. In keeping with other studies, we did not find that age or sex were predictive for satisfaction after joint arthroplasty 5, 9, 10, 11.
