Anti-inflammatory effects of intra-articular hyaluronic acid: A systematic review
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2021;9(22):18 Cartilage. 2018;10(1):43-52What this means for my practice?
HA produces molecular weight–dependent anti-inflammatory effects through a multifactorial mechanism of action via CD44, TLR, and I-CAM receptor signaling. High molecular weight HA combats the pro-inflammatory influences of fragmentized HA.
Study Summary
Forty-seven non-clinical, basic science articles describing the anti-inflammatory mechanism of hyaluronic acid (HA) treatment for osteoarthritis (OA) were included in this systematic review. The key findings were summarized based on the categorical inflammatory response; categories included HA-CD44, HA-TLR-4, HA-LAYN, and HA-ICAM-1 receptor responses.
