Biochemical and metabolic abnormalities in articular cartilage from osteo-arthritic human hips. II. Correlation of morphology with biochemical and metabolic data.

For thirty-two areas of cartilage from nine osteo-arthritic and four normal femoral heads a histologic-histochemical grade was assigned as an index of severity of the osteo-arthritic process. The DNA and hexosamine concentrations were determined as indicators of cell density and polysaccharide con
