The history and clinical application of artificial talus in Japan.
Review in International orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundArtificial talus has been used to treat severe ankle disorders, including avascular necrosis of the talus and ankle osteoarthritis, with favorable clinical outcomes. Consequently, joint-preserving surgery has become a viable treatment option even for hindfoot pathologies that previously required arthrodesis.
objectivesIn Japan, a novel alumina ceramic artificial talus has been developed, and several case series have demonstrated. The procedure combining an artificial talus with the tibial component of a total ankle arthroplasty (TAA) has been termed "combined TAA." This narrative review summarizes the historical development of the artificial talus and reviews its current clinical applications and surgical techniques.
methodsWe reviewed all published articles on artificial talus reported from Japan, as well as articles on metallic artificial talus used worldwide. In addition, we present characteristic cases from our own clinical experience that demonstrate the potential for the artificial talus.
resultsInitially, only a talar body prosthesis was used. However, complications frequently occurred at the junction between the talar body prosthesis and the talar neck, leading to revision surgery using a total talus prosthesis. Because the outcomes were favorable, the total talus prosthesis was adopted for primary surgery. Combined TAA has since been applied to revision TAA and ankle osteoarthritis. Furthermore, combined TAA can result in spontaneous correction of varus hindfoot malalignment, suggesting that combined TAA alone may be a viable treatment option even in cases previously thought to require calcaneal osteotomy or additional procedures.
conclusionsProcedures using artificial talus are promising. We believe that further innovations may expand the indications of artificial talus.
