Navigated versus non-navigated total knee arthroplasty: A large single-implant cohort analysis of clinical outcomes and survivorship.
Article in Journal of experimental orthopaedics, 2025. 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
Purpose: The aim of this study was to compare implant survival, clinical outcomes and radiographic alignment between navigated and non-navigated total knee arthroplasty (TKA) performed with a single implant system. Methods: A retrospective multicenter analysis of prospectively collected data from 6078 TKAs performed for primary osteoarthritis using a single implant system was performed. Procedures were divided into two groups: navigated ( Results: Five-year implant survival was similar between the non-navigated (98.9%; 95% confidence interval [CI], 98.2%-99.3%) and navigated (98.3%; 95% CI, 97.6%-98.8%) groups ( Conclusions: Navigation was equivalent to conventional instrumentation TKA with respect to implant survival. After adjusting for confounders and excluding septic revisions, navigated procedures showed a slightly higher reoperation risk. No significant advantage in functional outcomes was observed at mid-term follow-up. These findings do not support a clear clinical benefit for routine use of navigation in this setting. Level of Evidence: Level III, retrospective comparative study.
