Abstract

|
|
Purpose: The purpose of this study was to analyze the correlation between medial joint space on Rosenberg view and the degree of ultrasonographic medial meniscal extrusion.
Materials and Methods: Three hundred ninety knees with medial joint tenderness examined by ultrasonography were reviewed between January 2009 and May 2010. Medial joint space was divided into Grade I (≥ 4 mm), Grade II (3~4 mm), Grade III (2~3 mm), Grade IV (1~2 mm) and Grade V (0~1 mm). Then sonographaphic mid-medial extrusion of the medial meniscus was measured in each patient. After dividing into Group A that didn’t have large osteophytes (≥3 mm, medial joint at tibia) and Group B that had them, the correlation between the medial joint space and medial meniscal extrusion were analyzed in each group. One-way ANOVA & Scheffe test on the SAS program were used for the statistical analysis (p<0.05).
Results: There was a positive correlation between grade of the joint space and medial meniscal extrusion in Group A, but there was no positive correlation in Group B (p<0.05).
Conclusion: To the patients who didn’t have advanced osteoarthritis, the narrowing of the medial joint space was one of the predictive factors for mid-medial extrusion of the medial meniscus.
