Hyaluronic acid is an endogenous substance found in various tissues. The hyaluronic acid present in the joints is formed by the cells of the inner joint capsule and released into the synovial fluid. The synovial fluid prevents the cartilage from rubbing against each other. Depending on the stress of the joint, it changes its viscosity. Osteoarthritis reduces the concentration of hyaluronic acid in the joint and reduces the ability of the joints to glide. If hyaluronic acid is injected into the joint cavity, the joint's lubricity should be improved and the cartilage should be restored to hyaluronic acid.
3-5 injections of hyaluronic acid are required at intervals of about one week. If improved, re-injection therapy can be repeated in about 6 months
