Biochemical confirmation of an experimental osteoarthritis model
MG Ehrlich, HJ Mankin, H Jones, A Grossman, C Crispen and D Ancona
Section of the medial collateral and both cruciate ligaments combined with
resection of the medial meniscus in rabbit knees caused instability and
during the ensuing six months these knees showed progressive histological
changes similar to those of human osteoarthritis. Biochemical analysis of
the cartilage from such knee joints demonstrated a decrease in
proteoglycan, an increase in acid phosphatase, and increases in the rates
of synthesis of protein and glycosaminoglycan. These findings, which are
quite consistent with those in human osteoarthritis, suggest that this
animal model may be of value in the study of the pathogenesis and treatment
of human disease.
