  1. Intraobserver agreement for T2 measurements of native cartilage and repair cartilage tissue. ROI (Region of Interest) 1 and 2: sagittal plane, medial and lateral condyles, respectively. ROI 3: mid-sagittal, patella. ROI 4 and 5: coronal plane, medial and lateral condyles, respectively. Sag_repair and Cor_repair: sub-regions of repair tissue on sagittal and coronal images, respectively
