Hyaluronic Acid Injections

What is Hyaluronic Acid?

Hyaluronic acid is a naturally occurring molecule that occurs in the synovical fluid within the joints of our body.  The molecules are responsible for providing the joint synovial fluid with their viscoelastic properties enabling the smooth gliding action of the joint, shock absorption, proteoglycan synthesis and anti-inflammatory functions.


Why might I need to have or benefit from this injection?

When our bodies begin to degenerate and we develop the characteristics of osteoarthritis, our joints lose their elastic properties and smooth gliding action. The quantity and molecular weight of hyaluronic acid in the synovial fluid reduces.  The normally occurring abundance of hyaluronic acid in the synovial fluid is broken down and replaced throughout our life.  During the development of osteoarthritis and joint degeneration, the rate of hyaluronic acid depletion overtakes the rate of production and this imbalance contributes to the loss in cartilage integrity and advances joint degeneration.  These injections are not limited to the knee and hip, where they are most commonly used.  They can also be used in other smaller joints and even in cases of tendon pain.


Is the injection right for me?

If you are suffering from stiffness, aching or loss in range of movement then these injections will benefit you. You may have already undergone Focus Shockwave therapy or had a steroid injection.  Once your knee is calmer and is presenting with stiffness as the predominant symptoms, you are likely to respond most favourably. Where there are signs of swelling and pain, hyaluronic acid injections have been found to be of benefit. In some cases there may be a need to repeat the injection after 3 months.


What are hyaluronic acid injections and what do they do?

Hyaluronic acid injections enable the replenishment of hyaluronic acid molecules within a joint. This serves to improve joint fluid viscosity, protects the joint, helps with inflammation, enhance proteoglycan synthesis and improves the health of the cartilage.


What are Durolane and Ostenil injections?

There are two main types of Hyaluronic acid injection.  Durolane is a market leader because the molecular weight of the injection is higher making it longer lasting and providing patients with a longer yield of pain relief and enhanced function. Durolane is given as one injection.  Ostenil is given as a series of three.  Our preference at Core Body Clinic is to provide a longer lasting effect with less invaisive intrusion of the knee joint and we achive this with Durolane injections.


How long will the injection last?

Because of the high molecular weight of the Durolane injections, we expect patients to achieve a 8-16 months relief of symptoms.

Are there any risks?

There are no risks with Hyaluronic Acid.  There is a small risk of infection because the joint is to be injected.  However, other than this very small risk, there are no other side effects associated with Hyaluronic acid injections.


How are the injections given?

The injections are delivered from a sterile pack using a needle.  Guided injections using an Ultrasound scanning device is the standard method of delivery at Core Body Clinic.
