Articular cartilage. Part I. The normal joint

Abstract

Articular hyaline cartilage is of interest to both the clinician and the basic scientist because of its unique physical and chemical properties which are a consequence of its biochemical composition. Although it is a tissue which is hypocellular, avascular, and also lacks nerves and lymphatics, it is active in synthesis and degradation. Articular cartilage responds to the forces to which it is subjected and, in this way, maintains its integrity as long as those forces do not exceed the tissue's capacity for repair or permanently change the biologic response of the cells.
