Abstract
Background: Cementless fixation in total knee arthroplasty (TKA) has been associated with higher revision rates in the past. However, due to advancements in design, as well as surgical techniques, cementless TKA performance has significantly improved. The advantages of cementless fixation include reduced cement-related complications, shorter operating times, and the potential benefits of osseointegration. We aim to assess the improvement in revision rates for cementless TKA over the last 9 years based on international registry reports.
Methods: A comprehensive retrospective review was conducted of six major English-speaking knee arthroplasty registries across the world including the National Joint Registry of England and Wales, Northern Islan Isle of Man and Guernsey (herby referred to as British), Swedish, Canadian, American, Australian, and New Zealand National Joint Registry. Data was collected from the year 2014 along with the most recent annual report published: 2022 or 2023. Data points collected included usage rates of cemented and cementless prostheses for primary TKA, their respective revision rates, and indications for revision.
Results: Across four databases, there was an average 8.3% increase in the utilization of cementless fixation for primary TKA over the past decade. Three registries reported a reduction in revision rates for cementless fixation. Lower revision rates for cementless compared to cemented TKA were observed in the most recent American (3.2% cemented vs. 2.8% cementless) and New Zealand annual reports (11.8% cemented vs. 4.5% cementless). In 2022, the British registry reported lower rates of revision for infection with cementless fixation (0.56 vs. 0.89).
Conclusion: International registries demonstrate increased utilization of cementless TKA. Cementless TKA was reported to have lower revision rates in the most recent US and New Zealand annual reports when compared to cemented TKA.
期刊介绍：
The Irish Journal of Medical Science is the official organ of the Royal Academy of Medicine in Ireland. Established in 1832, this quarterly journal is a contribution to medical science and an ideal forum for the younger medical/scientific professional to enter world literature and an ideal launching platform now, as in the past, for many a young research worker.
The primary role of both the Academy and IJMS is that of providing a forum for the exchange of scientific information and to promote academic discussion, so essential to scientific progress.
