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.

Complex primary Total Hip Arthroplasty, where the decision whether a primary hip replacement is categorized as a complex procedure is left to the discretion of the treating physician
Periprosthetic joint infection excluded based on the EBJIS 2021 criteria
Every patient, regardless of sex or age, undergoing complex primary THA or aseptic revision hip arthroplasty, is eligible for inclusion in this study. This study will therefore also include children and women of childbearing age, although this is expected to be extremely rare. The decision on whether a primary hip replacement is categorized as a complex procedure is left to the discretion of the treating physician.
