| Background: Total hip replacement (THR) with post-operative surveillance is recommended for debilitating osteoarthritis (OA). Using self-reported pain, function or walking performance is one alternative to address increasing surveillance demands.;Participants: 110 patients, median 6 years after THR surgery for OA.;Methods: Questionnaires assessed demographics, co-morbidity, arthritis severity, pain, pain catastrophizing, and functional status. Performance was measured using the six minute walk test. THR outcome was assessed radiographically.;Results: Few patients had pain, functional impairment or radiographic markers of potential THR failure. A larger percentage of patients with some intermittent pain (10.7 versus 8.6%) and pain after walking performance (40.0 versus 27.6%) had higher wear, but these differences were not significant.;Objective: A cross-sectional cohort study to evaluate the associations of pain, function and performance with two radiographic markers of potential THR failure.;Conclusion: Measures of pain are potentially important for larger studies aiming to develop alternative methods of post-operative surveillance. |
