Acute Periprosthetic Joint Infection After Primary Total Knee Arthroplasty: Experience From a Secondary Public Hospital in Northern Mexico.
Article in Cureus, 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
Background Periprosthetic joint infection (PJI) is an uncommon but serious complication of total knee arthroplasty (TKA), and local data from secondary-level public hospitals in Mexico are limited. We measured the incidence of acute PJI after primary TKA at our hospital, described the patients who developed it, and established a local baseline for prevention and surveillance. Methods We retrospectively reviewed the medical records of 104 consecutive knee arthroplasty patients from October 2024 to September 2025. After excluding one revision and one bilateral procedure, 102 primary unilateral TKAs performed for osteoarthritis were analyzed. Acute PJI was defined by the Musculoskeletal Infection Society (MSIS)/2018 International Consensus Meeting and Infectious Diseases Society of America (IDSA) criteria. Cohort characteristics and the incidence of acute PJI (with a 95% confidence interval (CI)) were summarized descriptively. With only two events, we did not attempt inferential risk-factor analysis; instead, we describe both cases in detail. Results Two patients developed acute PJI, an incidence of 2.0% (2/102; 95% CI: 0.5-6.9%). The cohort was 56.9% female, with diabetes in 24.5%, hypertension in 44.1%, smokers in 5.9%, preoperative anemia in 13.7%, and no perioperative transfusions. One case was culture-negative with a sinus tract communicating with the joint (a major criterion); the other grew
