RATIONALE AND OBJECTIVES: The objective of the study was to assess the diagnostic efficiency of shear wave elastography in the grading of meniscal degeneration compared to magnetic resonance imaging (MRI) as a reference standard.

MATERIALS AND METHODS: Fifty patients were included in the study (who had bilateral knee MRI). Tissue elasticity was measured in the coronal plane from the meniscus body in kilopascal. Nonparametric testing (Mann-Whitney U) was utilized to assess the differences between mean elasticity of the meniscus tissue, gender. The inter-intraobserver agreement was determined by the intraclass correlation coefficient. The correlations between the mean elasticity of the meniscus versus age, height, and body mass index were calculated via the "Pearson Correlation Coefficient Test." The relationship between MRI meniscal degeneration grading and elastography elasticity module was determined via the "Spearman Correlation Test." A p value less than 0.05 was considered statistically significant.

RESULTS: İnter-intraobserver intraclass correlation coefficient of the lateral and medial meniscus mean stiffness values were good or excellent (>0.8). A statistically significant increase in stiffness of meniscus tissue was observed with an increase in age (p = 0.003 for medial menisci, 0.006 for lateral menisci). Tissue stiffness was higher in the medial meniscus than the lateral meniscus (p < 0.001). A positive correlation was observed between the MRI meniscal degeneration grade and tissue stiffness (p < 0.05). Additionally, mean stiffness values from lateral and medial menisci were higher in the group with degeneration (p < 0.0001).

CONCLUSION: Meniscus stiffness is increased with aging. There was a statistically significant positive correlation between meniscal stiffness and degeneration grading in MRI.
