Does body mass index (BMI) significantly influence aseptic loosening in primary total knee arthroplasty? Insights from a long-term retrospective cohort study.
Article in BMC musculoskeletal disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundTotal knee arthroplasty (TKA) offers substantially improved function for patients with severe osteoarthritis, but long-term success can be overshadowed by aseptic loosening, a complication with a multifactorial etiology. This study aims to investigate the association between BMI and the rate of aseptic loosening and other complications in patients undergoing primary TKA.
methodsThis retrospective cohort study examined 354 TKA patients, evenly categorized by BMI (≤ 30 kg/m² and > 30 kg/m²). Demographics, imaging findings, surgical details, and postoperative complications were assessed. Survival for postoperative complications was compared between the two BMI cohorts using Kaplan-Meier analysis.
resultsThe mean age of patients in the BMI ≤ 30 group was 62.44 years, while it was 62.84 years in the BMI > 30 group. The number of patients with short-stemmed tibial components was comparable in the two groups. Out of the total patients, 350 cases showed no loosening, while four experienced aseptic loosening. There was no statistically significant difference in the rate of aseptic loosening or other complications between the two groups.
conclusionWhile a high BMI may contribute to aseptic loosening, it does not appear to be the sole determinant. A multifactorial approach to prevention and management is essential, considering patient-specific factors and prosthetic considerations. Future research with larger cohorts and extended follow-up periods is needed to better elucidate the interplay between BMI and aseptic loosening in patients undergoing TKA.
