2. Figure 1. Strong Spearman's correlations r (95% CI) were observed between ultrasound and MRI medial osteophyte grades (A), and ultrasound and MRI lateral osteophyte grades (B). Strong and moderate associations were found between ultrasound and MRI medial cartilage grade (C), and medial cartilage ultrasound and MRI - full thickness loss grade (D), respectively. The relationship between ultrasound and MRI lateral cartilage grades was substantial (E) to low (F). All observed correlations hat statistical significance level of p< Kruskal-Wallis post hoc test indicated the significant difference between separate MRI grades (*p<0.05, **p<0.01, ***p<0.001).

3. Figure 2. The ROC curves demonstrating the ability of ultrasound to detect OA in separate sites of the knee joint. Site-specific MRI grade was used to determine the absence (grade = 0) or presence (grades ≥ 1) of OA. The area under the curve (AUC) indicated excellent ability of ultrasound medial (A) and ultrasound lateral (B) osteophyte grades to detect any osteophyte in the specific compartment. Good diagnostic ability of ultrasound medial cartilage grade to recognize any cartilage loss (C) and full thickness loss (D) in the region was observed. AUC indicated fair diagnostic performance of ultrasound lateral cartilage grade to detect any cartilage loss (E) and full thickness loss (F) in the region.
