En, Group En, non- or early osteoarthritis without meniscus tear; Ep, Group Ep, non- or early osteoarthritis with meniscus tear; Ap, Group Ap, advanced osteoarthritis and with meniscus tear; C, Group C, control group; MME, medial meniscus extrusion. P1, on radial MRI coronal slices were made radially from the anterior to posterior horns of medial meniscus, with the anterior horn slice as position 1 and the posterior horn slice as position 13
