Annual Hospital Case-Volume is Associated with Ten-Year Survival of Revision Total Knee Arthroplasty
Description
This presentation, delivered by Liam Yapp, a registrar from Edinburgh, discusses a compelling study examining the long-term survival rates of revision total knee arthroplasty (TKA) in Scotland. The study investigates the correlation between annual hospital case volume and ten-year survival rates of revision surgeries conducted over a two-decade span using the Scottish arthroplasty project dataset. Yapp emphasizes the escalating burden of knee arthroplasty cases and the unclear longevity of revision procedures.
The research is retrospective and observational, focusing on revisions characterized by permanent component removal or exchange, with an interest in annual case volume as a factor influencing outcomes. The findings reveal that nearly 9,000 revisions were carried out in this timeframe, noting a significant percentage attributed to infections. Notably, the results indicate that hospitals performing more than 20 revisions annually witness a substantial reduction in the risk of further revisions. Yapp points out that various explanatory variables were considered, but annual hospital case volume emerged as a key determinant of outcomes.
The presentation further highlights important data on the demographics of patients undergoing re-revision, the overall survival rate of 87% at 10 years, and the implications of the results in the context of healthcare delivery models like 'hub and spoke.' In conclusion, Yapp suggests that increasing hospital case volume could enhance patient outcomes in revision knee arthroplasty and invites further discourse and exploration through accompanying resources.
