1,What are hyaluronan injections?
Hyaluronic acid is a natural component of synovial fluid.
Hyaluronan injections help to lubricate joints, which gives you
temporary pain relief.
2,How do I take hyaluronan injections and how long do they take to
How often you have the injections depends on the type of hyaluronan
preparation used. You’ll probably be given a course of 3–5
injections, each separated by 1–3 weeks. Some doctors give the
first two injections close together and then extend the period
between those remaining. You probably won’t need to rest the joint
after the injections.
The injections should work within days if they’re effective and
they’ll probably last for a few months. Sometimes your doctor may
recommend you have repeat courses.
The particles in hyaluronan are quite large, so they’ll stay in
your joint for some time before they’re absorbed into your blood
stream. Some of the hyaluronan preparations available contain
significantly larger particles than others and this can influence
your doctor's choice.
3,What are the possible side-effects of hyaluronan injections?
Hyaluronan injections have very few side-effects, although some
people have a slight allergic reaction, which causes temporary pain
and swelling in their joint after the injection. There’s also a
small risk of infection. If the injection is done in slightly the
wrong place, it won’t damage your skin or muscle.

cartilage for protection. This product has the function of
lubrication and buffering.
2. Reduce or eliminate arthralgia with the connection with pain
receptor or mass molecular medium.
3. Restrain arthralgia caused by inflammatory mediator, such as
4. Restrain articular cartilage from cataplasia, and prevent from
adhesion and contracture.
5. Promote synoviocytes to excrete more sodium hyaluronate and
resume natural biochemical component of joint fluid.
6. Prevent tendon from adhesion.
