Knee pain is defined as discomfort due to overuse or during normal physical activity. Knee pain involves several surrounding tendons, cartilage, and ligaments.

Sudden, sharp pain is caused by fractures, ligament sprains, tendon tears, meniscus injuries, knee dislocations, or patellar dislocations. Chronic knee pain is usually a sign of various forms of arthritis.

The intra-articular hyaluronic acid injection is for the relief of joint pain caused by joint degeneration. The body naturally produces hyaluronic acid to lubricate joints and keep them functioning smoothly. It also acts as a natural shock absorber, preventing the bones from taking on the full force when stressing the joint.

Joint degeneration is a condition in which the hyaluronic acid is reduced in the affected joint. Thus, injecting hyaluronic acid into the joint adds the substance’s supply to the body, renewing the joint’s ability to lubricate itself and absorb shock.

Hyaluronic acid is injected into the joint. The sedative effect of the substance begins after a few days.

Hyaluronic acid injections are given into a joint to provide several months or a year of pain relief. The most common short-term side effect is minor pain at the injection site. The side effects improve within a few days.
