Long-term Aseptic Revision & Advanced Hip Arthroplasty Database

Total hip arthroplasty (THA) volumes continue to rise each year as the population ages and indications broaden. Increasingly, younger patients require hip replacement for conditions beyond primary osteoarthritis or fractures. As a result, the number of revision procedures is growing and is expected to increase further. Prospective data collection within this population will enable us to address key uncertainties, particularly around optimal implant selection for complex primary and revision cases. In addition, establishing a structured prospective database will allow for systematic internal auditing for quality assurance. Even simple metrics - such as verifying whether every patient received a complete diagnostic infection workup before revision surgery - could immediately enhance service quality and inform improvements to clinical pathways.

Inclusion Criteria: * Patients undergoing a hip replacement for the following indications: 1. THA with hardware removal 2. THA for hip dysplasia 3. THA with femoral deformity or prior corrective surgery 4. THA after LCPD, SCFE or septic arthritis 5. THA in metabolic disease 6. THA in hyperlaxity (e.g. Ehlers-Danlos syndrome, Down syndrome) 7. THA with complex bony anatomy 8. THA in patients aged 25 years or younger 9. Other indications for which the treating surgeon expects increased surgical difficulty or increased risk of postoperative complications Exclusion Criteria: * Patients unable to provide written informed consent * Patients who prefer treatment outside of University Hospitals Leuven * Patients with proven PJI according to the 2021 EBJIS criteria * Patients undergoing standard, non-complex, hip replacement as judged by the treating physician.
