Fig. 1From: Change in knee structure and change in tibiofemoral joint space width: a five year longitudinal population–based studyA representative MR image of cartilage segmentation. The volumes of individual cartilage plates (medial tibia and lateral tibia) were isolated from the total volume by manually drawing disarticulation contours around the cartilage boundaries on a section by section basis, before being re-sampled for 3-D renderingBack to article page
