Repro. = Intra-operator reproducibility, as determined by the root mean square SD for test-retest in 4 knees; Diff. = difference; ACdAB_Cov/ACdAB_Uncov = ACdAB covered/uncovered with meniscus; Th = thickness of the menisci; Width = width of the menisci; TA_Uncov = TA of the meniscus not covering the tibial platea; Ex = extrusion; OvD = overlap distance; Bul_Mean = mean bulging of the meniscus; _Max = maximal.
