Hyaluronic acid injections

What is it?

Hyaluronic acid (OSTENIL® PLUS) is an injection treatment for early osteoarthritis of synovial joints. Hyaluronic acid is a constituent of the normal synovial lubricating fluid in joints within the body. When a joint becomes arthritic they typically have lower concentrations of hyaluronic acid in the synovial fluid reducing its ability to lubricate the joint and cushion the articular cartilage. This can lead to pain, stiffness and swelling within the joint. Ostenil injections act by restoring the natural balance of production and breakdown of synovial fluid, therefore restoring some of the function and allowing reduced pain and improved lubrication of the joint. It also has a local anti-inflammatory effect. As such, hyaluronic acid injections when placed directly into the joint can improve the pain and stiffness of early osteoarthritis.

What's involved?

The injection is performed in the clinic under sterile conditions directly into the affected joint either under direct vision or occasionally ultrasound guidance.

What happens afterwards?

Typically patients will not notice an improvement immediately and in some instances the joint can ache a little bit more than normal for a couple of days after the injections. Over the next week or two inflammation within the joint should improve and the pain and stiffness ameliorate.

What joints can be helped by hyaluronic acid injections?

Most major joints of the body including the hip, knee, shoulder ankle and spine can benefit from hyaluronic acid injections under the right circumstances.

What are the risks associated?

As with all injections there is a small risk of introducing infection causing some minor bleeding or damaging some nerves around the joint. This is however a very low risk procedure.

Frequently Asked Questions

Ostenil plus is a single injection that has been shown to work in the majority of patients for a number of months or up to a year in scientific studies.

2) Are there any activity restrictions afterwards?

We would normally not recommend performing strenuous activity for a couple of days after the injections
