Hyaluronic acid (HA) is a polysaccharide with a structural function, just like the chondroitin sulfates that exist in the human body. One of the features is the retention of large amounts of water and therefore it acts as a lubricant and a mosturising.
Sportsmen use it for joint injuries such as sprains. It speeds up the recovery in early degenerative processes. It can even recover top layers of the cartilage and favour the structure and density of the cartilage cells.
Patients, who suffer from osteoarthritis, lose the viscoelasticity of the fluid (HA). The molecular weight (size) of hyaluronan in cartilage decreases with age, reducing the lubricating and buffer functions, what produces a mechanical joint loading and the destruction of the articular cartilage. The result will lead to the appearance of pain and limited joint mobility.
HA infiltrations can improve the viscoelasticity of the synovial fluid. These infiltrations can be made on different cycles, quarterly or yearly depending on the quality of the products introduced. It must be done in sterile conditions (ultra-clean) and under the strict criterion of your orthopaedic surgeon.
