Longitudinal Outcomes of Total Hip Arthroplasty in Developmental Dysplasia of the Hip: A National Database Propensity-Matched Analysis.
Article in Journal of the American Academy of Orthopaedic Surgeons. Global research & reviews, 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
introductionDevelopmental dysplasia of the hip (DDH) complicates total hip arthroplasty (THA) due to altered anatomy and biomechanics, increasing surgical complexity and postoperative risks. Although its effect on THA outcomes has been studied, data on long-term implant performance and revision surgery rates remain limited. This study uses a large, propensity-matched cohort to assess 90-day medical complications and 2-year mechanical outcomes in patients with DDH undergoing THA, addressing critical gaps in the literature.
methodsA retrospective cohort study using the TriNetX Research Network analyzed data from 104 healthcare organizations. Patients with DDH undergoing THA (n = 5908) were matched with control subjects (n = 5908) based on age, sex, BMI, and comorbidities. Outcomes included 90-day medical (infection, sepsis, thromboembolism, myocardial infarction, and mortality) and 2-year mechanical complications (reoperations and implant failure). Analyses included risk differences (RD), risk ratios (RR), Kaplan-Meier survival, and P-values.
resultsNo notable differences were observed in 90-day medical complications between DDH and control cohorts. However, patients with DDH demonstrated significantly higher risks of 2-year mechanical complications: revision surgeries: RD: 0.011 (95% CI, 0.005 to 0.017, P = 0.000); RR: 1.492 (95% CI, 1.199 to 1.858). Implant failure: RD: 0.012 (95% CI, 0.005 to 0.018, P = 0.001); RR: 1.394 (95% CI, 1.152 to 1.687). Kaplan-Meier survival analysis further confirmed significantly lower revision surgery-free survival (log-rank P = 0.001) and implant survival (log-rank P = 0.002) in patients with DDH compared with control subjects.
conclusionDDH increases 2-year mechanical complications post-THA, emphasizing the need for tailored surgical planning. The absence of increased 90-day medical complications supports perioperative safety. Future research should optimize long-term outcomes through innovations in implant design and surgical techniques.
