Parkinson's Disease Patients Face Higher 90-Day Readmission, Reoperation, and Infection Risk Following Total Knee Arthroplasty.
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: Parkinson's disease (PD) is an increasingly common comorbidity in patients undergoing total knee arthroplasty (TKA), yet its impact on readmissions remains poorly defined. Methods: Using the Nationwide Readmissions Database 2020-2022, we identified elective, primary TKA cases. Patients with oncologic diagnoses, COVID-19-related admissions, acute fractures, and contralateral knee arthroplasty were excluded. Only the first readmission within 90 days was analyzed. Propensity score matching (1:1) was performed for demographics, comorbidities, hospital factors, and primary payer. The primary outcome was 90-day readmission. Secondary outcomes included infection-related readmissions, surgical procedures during readmission, readmission length of stay, readmission costs, and in-hospital mortality. Results: After matching, 7286 patients were included (3675 PD vs 3611 non-PD). PD patients had a significantly higher 90-day readmission rate (13.0% vs 7.3%; Conclusions: PD is associated with a significantly higher risk of 90-day readmission following TKA, with readmissions frequently involving infection-related complications and surgical intervention. These findings highlight the importance of tailored perioperative care and enhanced postdischarge monitoring in this vulnerable population. Levels of Evidence: Level III.
