Viscosupplementation: Understanding Joint Lubrication Therapy, Hyaluronic Acid Function, and Pain Relief Mechanisms
Viscosupplementation is a therapeutic procedure used to relieve knee pain associated with osteoarthritis. It involves injecting hyaluronic acid (HA) into the affected joint, restoring lubrication and cushioning properties of synovial fluid. Hyaluronic acid acts as a shock absorber, improving mobility and reducing discomfort.
The treatment benefits individuals who do not respond adequately to physical therapy, oral medications, or lifestyle modifications. Depending on the formulation, viscosupplementation may involve a single injection or a series of injections delivered over several weeks.
Advancements in HA technology include cross-linked formulations that offer longer-lasting results and improved elasticity. Some patients experience relief for several months, delaying the need for surgical intervention. As research progresses, new formulations aim to enhance bioavailability and reduce inflammation more effectively.
