Waist-To-Hip Ratio Is More Predictive of Patients-Reported Outcomes After Total Joint Arthroplasty Than Body Mass Index: A Prospective Cohort Study.
Article in Orthopaedic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesObesity has an important impact on the future of total joint arthroplasty (TKA). We aimed to determine whether waist-to-hip ratio (WHR) is a useful measurement in predicting postoperative outcomes associated with obesity in patients undergoing primary TKA and compared the predictive value of WHR to that of body mass index (BMI).
methodsProspective data from patients undergoing unilateral primary TKA from February to May 2024 were analyzed, including BMI and WHR. Outcomes included complications, hospitalization details, and 12-month patient-reported function (University of California, Los Angeles [UCLA] activity scale, the Hospital for Special Surgery [HSS] score). Multivariable regression models were used to identify significant obesity-related predictors of outcomes.
resultsA total of 195 patients were included, with the mean BMI of 28.2 ± 5.2 kg/m
conclusionsThe WHR demonstrates superior predictive value over BMI for perioperative complications and 12-month patient-reported functional outcomes following primary TKA. Preoperative WHR assessment may help surgeons improve risk stratification and better educate obese patients regarding postoperative expectations prior to elective TKA.
