Biomarkers of incident radiographic knee osteoarthritis: Do they vary by chronic knee symptoms?

Abstract

Higher baseline ln(COMP) and ln(HA) levels were associated with incident knee OA over an average followup period of 6.3 years. These results represent detection of a molecular stage of OA prior to radiographic manifestations. Further exploration is needed to determine how chronic knee symptoms modify the biomarker-incident knee OA association.
