Medial meniscus extrusion is a determinant factor for the gait speed among MRI-detected structural alterations of knee osteoarthritis

Medial meniscus extrusion is directly correlated with medial tibial osteophyte in patients received reconstruction surgery for anterior cruciate ligament injury: A longitudinal study

“…MME has recently been attracted attention as an important abnormality related to the progression of knee OA [ 9 , [32] , [33] , [34] , [35] , [36] ]. Since meniscus is essential to protection of the articular cartilage from concentrations of mechanical stress and contributes to load distribution [ 3 ], MME is considered to cause increased mechanical stress to the medial sites of the tibial and femoral cartilage because of an increase in area of the tibia uncovered by meniscus.…”

“…However, medial meniscus disposition occurs not only medially (MME) but also anteriorly, and the anterior deviation of the meniscus is called as anterior meniscus extrusion (AME) [ 9 ]. In case of changes in position and/or morphology of the meniscus, mechanical force to the articular cartilage is inadequately dispersed and the overall biomechanics of the knee joint are altered, resulting in increased risk for cartilage loss and incidence and progression of knee OA [ 3 , 8 , [10] , [11] , [12] , [13] , [14] , [15] , [16] ]. Actually, MME is known to be an important risk factor for the incidence and progression of knee OA [ 14 , [17] , [18] , [19] ].…”
