Abstract
Scanning electron microscopic studies revealed numerous humps on the surface of articular cartilage from a 7 yr old boy and from 1 mo. old rabbits. The surface topography of articular cartilage in young individuals is different from that of older individuals (human and rabbit) where the surface is covered with numerous pits. In 2 mo. old rabbits an intermediate situation was witnessed, for both shallow pits and occasional humps were present. Ridges and undulations were not seen on the articular surface of the 7 yr old boy, except near the cut edge of the specimen. The ridges and undulations perhaps are not a constant feature of the normal articular surface, but are artefactual, atypical or pathological features.
