Visco-supplementation is a medical procedure aimed at treating osteoarthritis, particularly in the knee joint. It involves the injection of a thick, gel-like substance called hyaluronic acid directly into the joint space. Hyaluronic acid is a naturally occurring lubricant and shock absorber found in the synovial fluid surrounding joints. In osteoarthritis, this fluid becomes thinner, leading to increased friction and pain during joint movement.

The injected hyaluronic acid in visco-supplementation acts as a lubricant and cushion, improving joint mobility and reducing discomfort. This procedure is often recommended when conventional treatments such as pain medications or physical therapy do not provide sufficient relief. Visco-supplementation aims to alleviate symptoms, enhance joint function, and potentially delay the need for more invasive interventions like joint replacement surgery.
