Outcomes of Total Knee Arthroplasty With Simultaneous Contralateral Knee Intra-articular Corticosteroid Injection.
Article in Arthroplasty today, 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: Corticosteroid injections are a nonoperative management option for patients with osteoarthritis (OA) of major joints. Joshy et al. and Avila et al. showed that there is an increased risk of prosthetic joint infection if corticosteroid injections are administered within 90 days of arthroplasty on the same joint. Little is known about the infection risk, postoperative complications, and pain outcomes if contralateral knees are injected perioperatively or intraoperatively. Methods: This retrospective cohort study investigated patients with bilateral knee OA (n = 390) from January 2014 to December 2024 at a multilocation health system. Patients who received an intra-articular corticosteroid injection simultaneously with contrlateral total knee arthroplasty (TKA) (n = 195) were compared with controls who received no injection within 90 days of surgery (n = 195). Medical records were reviewed for comorbidities, total perioperative dexamethasone administration, total morphine milliequivalents, and postoperative complications. Results: Female patients (n = 246) were 63.1% of the total cohort. Average age of the population was 67.3 (standard deviation = 9.19). Mean body mass index was 33.2 (standard deviation = 6.39). Medical comorbidities did not significantly differ ( Conclusions: Patients who underwent TKA with steroid injection the same day of the contralateral knee did not have statistically significant different outcomes compared to patients who underwent TKA without steroid injection. Thus, contralateral steroid injections at the time of TKA may be safe in patients with bilateral knee OA.
