Osteoarthritis, although classically conceived of as a degenerative consequence of aging, is a disease with an increasingly
well-characterized molecular pathophysiology. Pathologic changes in cartilage composition and molecular organization, as well
as elevated water content, alter the exquisite balance of biomechanical properties. Much of what is known about changes in
the extracellular matrix in osteoarthritis comes from animal models.
Previously, thermogravimetric methods have not been used for compositional thermoanalytical study of normal and degenerative
human hyaline cartilage. For this reason the research group established a sufficient new thermogravimetric protocol, which
proved water content elevation contributing to disease progression.
