Relationship between Pain and Medial Meniscal Extrusion in Knee Osteoarthritis

Figure 2

Relationship between pain and medial meniscal extrusion or the cartilage thickness of the femoral medial condyle. The average cartilage thicknesses of the knees with and without pain were 1.02 and 1.05 mm, respectively, with no significant difference (). The average medial meniscal extrusions (MMEs) of the knees with and without pain were 7.58 and 5.88 mm, respectively; knees with pain had greater MMEs than knees without pain ().
