Can We Predict Posterior Cruciate Ligament Degeneration with Functional Tests?
Article in Maedica, 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
Objectives: The PCL (posterior cruciate ligament) is the primary stabilizer to prevent posterior translation of the knee. It provides femoral roll-back, stability and proprioception. Pathology of the PCL are limited in the literature. The aim of this study was to histopathologically examine the PCL of patients undergoing total knee arthroplasty for gonarthrosis and to investigate the correlation of PCL histopathology with preoperative functional scores. Materials and methods: Seventy-three patients (19 males, 54 females) aged 50-75 years, with primary osteoarthritis, where bilateral knee arthroplasty was performed in three patients, resulting in 76 tibial plateaus, were included in the present study. Patients with a history of previous intra-articular knee surgery and rheumatic disease were excluded. Posterior cruciate ligament materials were graded between stages 0 and 4 according to the extent of histopathological changes recorded under light microscopy. Correlation of PCL histopathology with preoperative functional scores. SF-36 limitations of activities and physical health problems, Pain Quality Assessment Scale (PQAS), Lysholm and WOMAC scoring systems were assessed preoperatively. Results: There were significant correlations between light microscopic histopathologic staging of PCL and preoperative SF-36 limitations of activities (p<0.01), physical health problems (p<0.05); PQAS intense (p<0.05), radiating (p<0.01), throbbing (p<0.05), aching (p<0.05), heavy (p<0.05); Lysholm total (p<0.001); and WOMAC total scores (p<0.01). The correlation between histopathologic staging of PCL and using a cane or crutches of Lysholm and radiating of PQAS was found to be moderately significant (p<0.001, p<0.01). Conclusion: Despite significant correlations, the commonly used functional scores may not be sufficiently precise for granular preoperative assessment of PCL microscopic degeneration, highlighting the need for PCL-specific scoring systems.
