Viscosupplementation is the process of injecting hyaluronic acid into the knee joint. This substance acts a lubricant to provide shock absorption for joint loads and to help the bones move smoothly over each other. Hyaluronic acid occurs naturally in the fluid of the joints; knee pain sufferers often have a lower concentration of hyaluronic acid in their joints. This technique has been proven to relieve pain in patients who are unable to benefit from rehabilitative practices or analgesic medications.
