Schematic illustrations of normal knee joint and osteoarthritis knee joint with osteophyte and medial meniscal extrusion (MME). a Normal knee joint. Medial meniscus is tightly fixed to the coronary ligament in the medial tibial plateau. b Relationship between MME and medial tibial osteophyte distance based on observations by conventional magnetic resonance imaging (MRI). Note that MME distance appears to be longer than osteophyte distance. c Relationship between MME and medial tibial osteophyte distance according to the findings obtained by T2 mapping MRI. Note that the edge of the extruded medial meniscus matches that of the cartilage part of the osteophyte. Bp Bone part of osteophyte, Cp Cartilage part of osteophyte, M Medial meniscus
