The aim of this study was to investigate the variation in cartilage characteristics with age. Fresh-frozen cryostat sections of the patellar articular cartilage of the rat were used to demonstrate the enzyme activity of succinate dehydrogenase, lactate dehydrogenase, alkaline phosphatase, and acid phosphatase in the different layers and at different ages. Light microscopic techniques were used to analyse quantitative features such as thickness, cell density and the histological characteristics of the articular cartilage. The results indicate that cell density is significantly affected by age. Furthermore, it depends on the distance from the surface. The most marked decline in cell density occurred between months 3 and 6. The thickness of the articular cartilage also varies with age. The reduction in cartilage thickness was most striking between months 3 and 6. Differentiation into the histological layers is obvious after 3 months. Glycolytic enzymes were strongly reactive in all regions and at all ages, whereas aerobic activity declines with age. The metabolic and morphological changes in ageing cartilage contribute to trophic disorders and deterioration of the functional cartilaginous situation in adult cartilage.
