<bold>FIG. 108.1.</bold> Degenerative joint disease of the knee. Large areas of erosion of articular cartilage are present on the patellar facet and on the condyles of the femur. These erosions occupy principally the central portions of the joint surfaces and spare the marginal regions. The cartilage at the eroded edges is fi illated. The irregular elevations at the periphery of the surfaces are osteophytes.

<bold>FIG. 108.8.</bold> Heberden node. The articular cartilage has completely disappeared from the surfaces of the distal interphalangeal joint. Bony osteophytes, directed toward the base of the finger, are present on the dorsal and palmar aspects of both articulating surfaces. Advanced osteoarthritic changes also are present in the proximal interphalangeal joint and form a so-called Bouchard node. (Hematoxylin and eosin stain, original magnification 320.)
