Analysis of 516 cases of revision total elbow arthroplasty from the Dutch Arthroplasty Registry: centralization of care is the future

Background: The number of revision total elbow arthroplasty (TEA) remains relatively low. As a result, there are relatively few orthopedic surgeons and a limited number of centers with substantial expertise in revising TEA. This study provides a comprehensive description of the current practice concerning revision TEA in a northern European Country based on the data of the Dutch National Implant Registry. Methods: Data of all revision TEA procedures performed between 2014 and 2022 were extracted from the national registry, including cases where the primary procedure was either not recorded in the registry or was not a TEA. Descriptive statistics were used to report the current practice of revision TEA in the Netherlands. Results: Five hundred sixteen revision TEAs were performed in the Netherlands between 2014 and 2022. Eighty-four elbows required more than one revision during that period. The primary cause for revision was aseptic loosening 51%. The procedures were performed in 35 centers, and 21/35 centers performed 5 or less revision procedures per year. No center performed 20 or more revision procedures per year. Discussion: All types of elbow arthroplasty are associated with a considerable rate of complications, and a direct volume-outcome relationship exists in these surgical procedures. Despite the considerable complication rate, the volume of revision TEA remains low, primarily due to the infrequent occurrence of primary procedures. Conclusion: The study reported that aseptic loosening was the primary reason for revision TEA. We recommend centralizing infrequent surgical procedures such as revision TEA in selected highly specialized centers to increase surgeon and center volumes, aiming to yield more favorable outcomes.
