Hamstring Graft Diameter and Clinical Outcomes in Anterior Cruciate Ligament Reconstruction: A Retrospective Cohort Study.

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
purposeThe outcomes of anterior cruciate ligament (ACL) reconstruction can be influenced by multiple factors, including surgical technique, graft type, and fixation methods. While existing literature has extensively examined these variables, less attention has been given to the impact of graft diameter. This study aims to evaluate the effect of hamstring graft diameter on clinical outcomes and recurrence rates following ACL reconstruction, addressing a significant gap in the current research.
methodsWe conducted a retrospective analysis of prospectively collected data from 107 patients who underwent ACL reconstruction with a quadrupled hamstring tendon autograft between 2007 and 2019 at Via Grumo 16, Gravesano, Switzerland. Patients were divided into two groups based on graft diameter: 5-7 mm and ≥8 mm. The primary outcome was knee stability, assessed using the KT-1000 arthrometer at six, 12, and 24 months post-surgery. Re-rupture rates and other clinical outcomes were also evaluated. Statistical analysis was performed using Kaplan-Meier survival curves, Cox regression, and non-parametric tests, with a power analysis conducted to assess the adequacy of the sample size.
resultsNo significant differences in knee stability, as measured by KT-1000 scores, were observed between the two groups at any follow-up interval (p > 0.05). Re-rupture rates were also comparable, with no significant association between graft diameter and the risk of re-rupture identified (p > 0.05). The study's power analysis revealed that our sample size did not reach the 80% threshold, representing a notable limitation.
conclusionOur findings suggest that graft diameter may not significantly influence clinical outcomes in ACL reconstruction with hamstring tendons, challenging prior assertions of its critical role. Given the study's limitations, including its underpowered sample size, further research with larger cohorts is needed to validate these results and guide graft selection strategies.
