Hyaluronic acid (HA) injections are commonly used for pain management, particularly in osteoarthritis, by improving joint lubrication and cushioning. HA is a naturally occurring substance found in synovial fluid, which helps reduce friction and absorb shock in joints. In conditions like osteoarthritis, the natural HA in the joint degrades, leading to increased pain, stiffness, and inflammation. By injecting HA directly into the affected joint, typically the knee, it restores some of the lost viscosity, reducing friction between bones and alleviating pain. This treatment, known as viscosupplementation, can provide relief for several months, making it a popular non-surgical option for managing chronic joint pain.
Beyond lubrication, HA injections also have anti-inflammatory and analgesic effects. Research suggests that HA can inhibit inflammatory mediators and block pain receptors, further reducing discomfort. It may also promote cartilage health by stimulating cell growth and reducing breakdown. Patients who receive HA injections often experience gradual pain relief over several weeks, with the benefits lasting from six months to a year, depending on individual response. While HA injections do not cure underlying joint disease, they can significantly
improve mobility and quality of life, particularly for those who have not responded well to other conservative treatments like physical therapy or oral pain relievers.
