  1. SD: standard deviation; Diff(%): difference in percent; t-Test: unpaired t-test; ACdAB: area of cartilage surface, including denuded areas of subchondral bone; V: volume; TA: tibial area; FA: femoral area; EA: external area; TOT A: sum of all three surface areas of the meniscus; Th.Me: mean thickness of the meniscus; Th.Max: maximal thickness of the meniscus; Wid.Me: mean width of the meniscus; Wid.max: maximal width of the meniscus; TA.uncovp: tibial area of the meniscus not covering the tibial plateau in percent; Ex.Me: mean external extrusion; Ex.Max: maximal external extrusion; ACdAB.Covp: area of cartilage surface covered with meniscus in percent; OvD.Me: mean overlap distance; OvD.Max: maximal overlap distance. Note that a positive value for meniscal extrusion indicates an "external" position relative to the external border of the tibial plateau, whereas a negative value indicates an "internal" position relative to the external border. A more negative value for the overlap distance indicates a more internal position of the inner margin of the meniscus.
