Fatty Acid Modulation in Osteoarthritis Management
Summary
Osteoarthritis is a degenerative joint disorder marked by cartilage breakdown, synovial inflammation and subchondral bone remodelling. Emerging evidence implicates dysregulated lipid metabolism and altered fatty acid profiles in the pathogenesis of this condition. Polyunsaturated fatty acids (PUFAs), particularly the balance between omega-3 and omega-6 species, can influence inflammatory cascades, extracellular matrix turnover and chondrocyte viability. Dietary interventions, nutraceutical formulations and targeted intra-articular delivery of PUFAs have been investigated as potential disease-modifying strategies. Preclinical and clinical studies suggest that supplementation with marine-derived oils can upregulate chondrogenic gene expression, inhibit matrix-degrading enzymes and attenuate synovial inflammation. Advances in metabolomic profiling have also begun to identify specific lipid metabolites as biomarkers of disease progression and therapeutic response. Together, these developments underscore the global significance of fatty acid modulation in osteoarthritis management and point towards personalised nutritional and therapeutic programmes to preserve joint structure and function.

Fatty Acid Modulation in Osteoarthritis Management publication trend
The graph below shows the total number of articles in fatty acid modulation in osteoarthritis management across all publications each year (not limited to Nature Index journals).
Technical terms
Polyunsaturated fatty acid (PUFA): A fatty acid containing two or more carbon–carbon double bonds, including omega-3 and omega-6 subclasses.
Omega-3 fatty acid: A PUFA with its first double bond at the third carbon from the methyl end, known for anti-inflammatory properties.
Omega-6 fatty acid: A PUFA with its first double bond at the sixth carbon from the methyl end, often associated with pro-inflammatory mediators.
Chondrocyte: A specialised cell in cartilage responsible for synthesising and maintaining the extracellular matrix.
Synovium: The membrane lining joint cavities, which produces synovial fluid and can contribute to inflammatory processes.
Metabolomics: The comprehensive analysis of small-molecule metabolites within a biological sample, used to identify biomarkers and metabolic pathways.
