The Application of Optical Coherence Tomography in Musculoskeletal Disease

Figure 3

OCT of severely osteoarthritic cartilage. OCT (top) shows bone (b) and cartilage (c) with heavy cartilage loss on the left. The previously clearly defined cartilage/bone interface is destroyed, with a pathologic fibrous band on top (red arrows) and new bone growth (nb). Masson’s Trichrome (bottom) again confirms OCT, with cartilage (c), bone (b), new bone growth (nb), and a fibrous band (red arrow). Image courtesy of Hermann et al. [6].
