Intra-Articular Adelmidrol 2%/Hyaluronic Acid 1% With or Without m/umPEA, in Knee Pain Due to Joint Degeneration.

Degenerative knee joint diseases are characterized by chronic pain, inflammation, and functional impairment. In these conditions, mast cell density in the synovial membrane is increased, resulting in an excessive release of biological mediators involved in key mechanisms of neuroinflammation and in hyaluronic acid depolymerisation. Adelmidrol acts as a preventive antioxidant due to its radical scavenging activity, thus protecting hyaluronic acid from oxidative degradation and reducing mast cell degranulation. Furthermore, a reduction in endogenous Palmitoylethanolamide (PEA) levels also contributes to joint neuroinflammation and disease progression; therefore, its exogenous supplementation may represent a valuable supportive strategy.

The objective of this clinical investigation is to compare the efficacy of intra-articular adelmidrol/hyaluronic acid treatment alone versus the same intra-articular treatment combined with oral micronized /ultramicronized PEA in patients with knee joint degeneration due to osteoarthritis or rheumatoid arthritis.
