Traumatic knee dislocations: a national database analysis.
Article in BMC musculoskeletal disorders, 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
backgroundKnee dislocation is a rare but severe orthopedic emergency with a substantial risk of limb-threatening complications. This retrospective national database cohort study aimed to describe the epidemiology of traumatic knee dislocations and identify risk factors for vascular and neurological injuries.
methodsA total of 164 patients diagnosed with knee dislocation between 2016 and 2023 were included in this retrospective study. Data were obtained from the Ministry of Health system, and diagnoses were confirmed. Demographics, injury mechanisms, associated fractures, and complications were evaluated using International Classification of Diseases (ICD) codes. Logistic regression was used to identify independent risk factors.
resultsThe study population consisted primarily of males (81.7%) with an average age of 31.74 years. Vascular injuries occurred in 19.5% of patients, most commonly involving the popliteal artery. Neurological injury was present in 20.1%. In patients with open injuries, infection, vascular injury, amputation, debridement, and soft tissue defect repair were found to be significantly higher. Despite these findings, open injury was not an independent predictor of vascular injury in multivariate analysis. Charlson Comorbidity Index (CCI) > 0 independently predicted the need for vascular procedures. Younger age was associated with neurological injury. Intensive Care Unit (ICU) admission was associated with systemic injuries. The overall amputation rate was 1.2%.
conclusionTraumatic knee dislocations frequently involve serious neurovascular complications. While open injuries were associated with a more complicated clinical course, only CCI independently predicted the need for vascular intervention. Early recognition of patients with comorbidities and significant concomitant injuries may improve outcomes. LEVEL OF EVIDENCE: Level IV.
