Likelihood of secondary surgery due to osteoarthritis following ankle fracture fixation: a systematic review.
Synthesis in Journal of orthopaedic surgery and research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAnkle fractures are common injuries that can lead to long-term complications, including post-traumatic osteoarthritis. The rate of surgical intervention for osteoarthritis following fracture fixation is unclear. Understanding the burden of subsequent procedures is essential to inform patients and guide treatment strategies. This review investigates the risk of surgical interventions for osteoarthritis after surgical fixation of ankle fractures.
methodsWe performed a systematic review following PRISMA 2020 and registered the protocol in PROSPERO (CRD42024615284). We included studies of adults (≥ 16 years) with acute ankle fractures treated surgically who later required operative treatment for osteoarthritis. Two reviewers independently performed data extraction and risk-of-bias assessment (Newcastle-Ottawa Scale). Because of clinical and methodological heterogeneity, we synthesised findings narratively.
resultsFrom 2,425 records screened, eight cohort studies (n = 133,367) met inclusion criteria. The reported risk of ankle fusion or replacement due to osteoarthritis ranged from 0 to 4.2%, with mean follow-up ranging from 17 months to 21 years. One large registry study contributed the majority of patients.
conclusionsReported rates of re-intervention for post-traumatic ankle osteoarthritis are low in the short to medium term but interpretation is limited by heterogeneity, generally short follow-up, and reliance on a single large registry cohort. High-quality, long-term studies are needed to determine the true lifetime burden and modifiable risk factors.
