Figure 7: (a) Arthroscopic image of normal medial tibial cartilage. The red arrow represents a section of smooth normal looking cartilage. (b) and (d) MR image of the joint using T1 and T2 (top to bottom) relaxation states. The sagittal cross-section shows a uniformly homogeneous articular layer at the indicated point. (c) OCT image of area represented by the arthroscopic image. The OCT image shows a uniform banding pattern, indicative of healthy cartilage. Image courtesy of Zheng et al. [9].
