HA Injections for Osteoarthritis

Hyaluronic Acid Injections for Osteoarthritis of the Knee and Foot

Osteoarthritis is a degenerative joint disease that causes pain and loss of movement or function in your joints. It can greatly reduce your quality of life, particularly when it affects joints such as knees or smaller joints in the foot.

Hyaluronic Acid naturally lives within a healthy joint. Normally there is an exact balance between the breakdown of old hyaluronic acid and the production of new hyaluronic acid. In osteoarthritis, however, this balance is disturbed and breakdown happens faster than production. As a result, the lubrication in the joint (synovial fluid) becomes more watery and stops working properly.

Due to the change in the synovial fluid, amongst other processes, the cartilage in the joint gradually wears away. In some joints, the cartilage may eventually disappear altogether. The thinning of the synovial fluid and wearing away of the cartilage lead to the symptoms of osteoarthritis, which include pain, stiffness and swelling.

Hyaluronic injections serve as a shock absorber and lubricant to synovial joints. They work by restoring the normal balance between the breakdown and production of hyaluronic acid within the joint. These injections can decrease pain and stiffness and improve the other symptoms of osteoarthritis. 

The purpose of synovial fluid is not just to lubricate the joint, but also to act as a protective filter, allowing good nutrients to reach the cartilage and blocking the passage of harmful substances. One of the most important components of synovial fluid is hyaluronic acid.

At the Back and Body Clinic, we believe that your ability to continue to perform the tasks you enjoy matters and that us why we offer Hyaluronic Acid joint injections

Whilst the benefits from the injections might not be immediately noticeable, you will gradually experience a reduction in pain and stiffness and this improvement will likely persist for up to 9-12 months (in many cases), depending on the progression of the degenerative change in the joint being treated. We can use Cortisone and Hyaluronic Acid together for knee joint pain giving the combined effect of both substances.

The Hyaluronic Acid we use is called Ostenil. We have successfully treated many patients at the Clinic. It is a safe and effective injection with very few side effects- we will go through all of the risks and possible side effects with you before your injection.


Your suitability for this type of treatment will be discussed and we will always thoroughly examine you, inform you and gain consent prior to any injection.

Feel free to pick up the phone and ask to speak to someone about the injections we offer.
