A New Look at the Cross-sectional Relationship of Self-reported Pain, Function and Walking Performance with Radiographic Wear and other Early Indicators of Total Hip Replacement Failure in Patients with Osteoarthritis

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.
Objective: A cross-sectional cohort study to evaluate the associations of pain, function and performance with two radiographic markers of potential THR failure.
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 iii after walking performance (40.0 versus 27.6%) had higher wear, but these differences were not
significant.
Conclusion: Measures of pain are potentially important for larger studies aiming to develop alternative methods of post-operative surveillance.
