Visco supplementation is the process of injecting material into the joint which will biologically thicken the joint fluid. This treatment is typically done in a series of injections one week apart. The effect lasts on average six months and the treatment can be repeated. For patients with mild to moderate arthritis, visco supplementation can provide both cushioning and a lubricating effect. Some feel that this process may also slow cartilage degeneration. There is no recovery period following this treatment and, if done correctly, the injection causes minimal discomfort.
