Semiquantitative ultrasonographic grading of femoral cartilage: comparison among three knee groups with different clinical statuses.
Article in Clinical rheumatology, 2026. 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
introductionUltrasonography (US) can directly visualize the femoral condylar cartilage, but whether semiquantitative US grade distributions differ among knee groups with different clinical statuses in relation to total knee arthroplasty (TKA) for knee osteoarthritis (OA) remains unclear. We hypothesized that semiquantitative US grading would differ significantly among the three knee groups.
methodIn this prospective cross-sectional study, 60 patients scheduled for unilateral TKA for OA and 27 healthy young adults were recruited. Group A included knees scheduled for TKA; group B included the contralateral knees of the same patients that were not scheduled for TKA, and group C included bilateral knees of healthy participants. Each knee underwent semiquantitative US grading (0-6) of the whole, medial, and lateral femoral condyles. Differences were analyzed with chi-square trend tests and Wilcoxon signed-rank tests.
resultsUS grading differed significantly across the three groups at the whole, medial, and lateral femoral condyles (all P < 0.0001). Groups A and B each differed significantly from group C at all three regions (all P < 0.0001). Between groups A and B, grading differed significantly at the whole (P = 0.0222) and medial (P = 0.0017) femoral condyles, but not laterally (P = 0.1792). Medial grading was significantly higher than lateral grading in all groups (all P < 0.0001).
conclusionsSemiquantitative US grading of femoral condylar cartilage differed among three groups representing different clinical statuses in relation to TKA for knee OA. Grades at the medial femoral condyle were higher than those at the lateral femoral condyle in all three groups. Key Points • Semiquantitative ultrasonographic grading of the femoral condylar cartilage differed at the whole, medial, and lateral femoral condyles among three groups representing different clinical statuses. • The grading differed between knees scheduled for TKA and the contralateral knees of the same patients at the whole and medial femoral condyles, but not at the lateral femoral condyle. • Semiquantitative US grades were higher at the medial than at the lateral femoral condyle in all three groups. • Semiquantitative US grading is a non-invasive method for comparing femoral cartilage morphology among three groups representing different clinical statuses.
