Histopathological Evaluation of the Anterior Cruciate Ligament in Patients With Advanced Gonarthrosis.
Article in International journal of rheumatic diseases, 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
introductionKnee osteoarthritis is a degenerative disease of the knee joint that leads to progressive loss of articular cartilage. There is only limited information in the literature on the degeneration of the anterior cruciate ligament (ACL) in patients with gonarthrosis. In this study, ACL samples excised during the surgery of patients undergoing total knee replacement (TKR) in 2019-2020 were evaluated histopathologically. The present study aims to investigate the relationship between the degeneration of the ACL and the stage of gonarthrosis.
methodsDirect X-rays of 47 patients undergoing knee arthroplasty were evaluated and stratified into two groups: Stage 3 (Group 1) and Stage 4 (Group 2). ACL samples were examined histopathologically. Staining was performed with hematoxylin-eosin (H&E), Alcian blue, and Masson's trichrome. The degree of degeneration was determined according to the Movin score and Bonar score. Based on these scores, the statistical significance of the relationship between the stage of gonarthrosis and histopathological examination results was evaluated.
resultsWhen Group 1 patients were graded according to total Movin scores, the result was mild degeneration in 72.7% of the patients, while the corresponding rates were 76% in Group 2. None of the patients had a score reflecting severe degeneration. The total Bonar scores showed mild degeneration in 68.2% of Group 1 patients. In Group 2, the scores showed mild degeneration in 52% of the patients. No statistically significant difference was found between the groups in either scoring.
conclusionIt was determined that comparable degeneration occurred in the ACL with the progression of the stage of gonarthrosis.
