Outpatient Hip and Knee Arthroplasty in Obese Patients With Body Mass Index Above 40 kg/m
Article in Arthroplasty today, 2025. 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: Over 35% of the US population is obese, leading to earlier arthroplasty needs, increased comorbidities, surgical challenges, and higher complication and revision rates. Concurrently, outpatient hip and knee arthroplasty procedures are increasing. This study aimed to evaluate early complication rates of same-day discharge (SDD) arthroplasty in severely obese patients (body mass index [BMI] ≥40). Methods: We retrospectively reviewed 15,133 primary hip or knee arthroplasty patients from 2015 to 2022, divided into four groups: obese SDD (n = 247), obese overnight (n = 1123), nonobese SDD (n = 5184), and nonobese overnight (n = 8579). Results: Obese SDD patients were significantly younger than obese overnight patients (mean age 58.8 vs. 62.9 years, Conclusions: Our findings suggest that SDD for hip and knee arthroplasty can be safely performed in severely obese patients (BMI > 40) without significantly increasing early surgical complications. However, the inherently higher revision rate for high BMI patients undergoing joint replacement remains, irrespective of discharge timing.
