Mankin et al. analyzed 32 discrete cartilage sites from 9 osteoarthritic and 4 normal human femoral heads, correlating a newly devised histologic-histochemical grading system (scoring structure, cellularity, safranin-O staining, and tidemark integrity) with biochemical measures of cell density (DNA), polysaccharide content (hexosamine), DNA synthesis (³H-thymidine incorporation), and proteoglycan synthesis (³⁵SO₄ incorporation) to define how cartilage biology changes across the spectrum of OA severity.
This classic work established that osteoarthritis involves measurable biochemical and metabolic alterations that correlate with structural changes, helping frame OA as a disease process amenable to scientific investigation.
Understanding this correlation remains fundamental to comprehending how cartilage degradation progresses in osteoarthritis.
