Comparison of clinical, radiological, and second-look arthroscopic outcomes between hamstring autograft and tibialis allograft following remnant-tensioning anterior cruciate ligament reconstruction.
Article in Archives of orthopaedic and trauma surgery, 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
backgroundThe remnant-tensioning (RT) anterior cruciate ligament reconstruction (ACLR) has been reported to have excellent postoperative outcomes. However, the influence of graft selection on postoperative outcomes of autografts and allografts after RT-ACLR has been poorly investigated. The purpose of our study was to compare the clinical, radiological, and second-look arthroscopic outcomes of autografts and allografts following RT-ACLR.
methodsBetween January 2013 and May 2020, 94 and 64 patients were enrolled in auto (hamstring tendon) and allo (tibialis tendon) groups, respectively. For subgroup analysis, patients were divided into two age categories: ≤34 and > 34 years of age. Stability tests, including the Lachman and Pivot shift tests, side-to-side differences on Telos stress radiographs and KT-2000 arthrometer, patient-reported outcome measurements (PROMs), and graft status on postoperative magnetic resonance imaging (MRI) and second-look arthroscopy, were evaluated and compared between the two groups.
resultsThe two groups showed no statistically significant differences in stability outcomes or PROMs for patients aged ≤ 34 and > 34 years. Furthermore, both groups demonstrated comparable postoperative graft status on postoperative MRI and second-look arthroscopy analyses in patients aged ≤ 34 and > 34 years.
conclusionRT-ACLR using allografts yielded similar postoperative clinical outcomes, MRI findings, and second-look results compared to autografts, irrespective of patients' age. Therefore, allografts may serve as a viable option for patients scheduled for RT-ACLR.
