Comparison of the effects of endobutton continuous loop and adjustable zip loop devices on bone tunnel enlargement and clinical results in arthroscopic anterior cruciate ligament reconstruction: A retrospective observational study.
Observational study in Medicine, 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
It was aimed to reveal the effects of 2 different techniques [Endobutton Continuous Loop (CL), ZipLoop technique] used for graft fixation in anterior cruciate ligament (ACL) reconstruction on bone tunnel enlargement and clinical results. Patients who underwent arthroscopic ACL reconstruction using hamstring tendon graft due to ACL rupture between January 2016 and December 2020 were retrospectively analyzed. The study included 80 patients who were operated on by the same surgical team in the same clinic. Forty patients who underwent repair using the suspension system ZipLoop technique were classified as Group 1, and 40 patients who underwent repair using the Endobutton CL technique were classified as Group 2. Plain radiography and MRI were used to evaluate bone tunnel widening. Visual analog scale (VAS), International Knee Documentation Committee (IKDC) knee assessment score, and Lysholm scores were evaluated at the last follow-up to evaluate clinical outcomes. When bone tunnel enlargement was evaluated between the groups, femoral and tibial tunnel enlargement was found to be greater and statistically significant in Group 2 patients in direct radiography measurements. No statistically significant difference was found in tunnel enlargement in MRI measurements (P > .05). However, in MRI measurements, the graft apex-tunnel apex distance was found to be greater and statistically significant in Group 2 patients (P < .05). When the clinical results of both groups were compared, no statistically significant difference was found in VAS, IKDC and Lsyholm scores (P > .05). The graft fixation method affects bone tunnel enlargement. However, it was observed that this had no effect on clinical results.
