Comparison of three surgical methods for displaced posterior cruciate ligament tibial insertion avulsion fractures: a retrospective study.
Article in Journal of orthopaedic surgery and research, 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 aim of this study was to evaluate the clinical outcomes of three surgical methods, three types of arthroscopic suture fixation, suspension fixation with EndoButton, and open screw fixation, in the treatment of displaced posterior cruciate ligament tibial insertion avulsion fractures.
methodsA retrospective analysis of the clinical data of 104 patients with posterior cruciate ligament avulsion fractures between 2010 and 2023 was performed. The patients were divided into three groups according to the surgical approach used: suture fixation in Group A (24 patients), suspension fixation with EndoButton in Group B (37 patients), and hollow screw fixation in Group C (43 patients). The Lysholm score, International Knee Documentation Committee (IKDC) score, Tegner activity score, and postoperative imaging findings of all patients were collected. The final follow-up data were used to compare the differences among the three groups.
resultsThere was no statistically significant difference in the general information of the three groups of patients. Among the 104 patients, the mean postoperative Lysholm score was 92.9 (CI, 91.0-94.8) in Group A, 93.4 (CI, 92.3-94.6) in Group B, and 93.5 (CI, 92.6-94.4) in Group C. Postoperative IKDC subjective assessment of knee function was considered normal or near normal in more than 95% of the patients in all three groups. More than 93% of the patients in all three groups did not have severe abnormalities in knee range of motion. The mean postoperative Tegner activity score was 6.7 (CI, 6.3-7.1) in Group A, 7.0 (CI, 6.7-7.3) in Group B, and 6.9 (CI, 6.6-7.1) in Group C. Imaging at 3 months after surgery revealed bone healing, and no serious postoperative complications were found in any of the three groups.
conclusionAll three treatments yielded good clinical results and imaging healing. In particular, arthroscopic suspension fixation with EndoButton is recommended as the preferred treatment because of its low invasiveness, good mechanical properties and low complication rate.
