Common Conditions Treated with Hyaluronic Acid Injections

Hyaluronic acid is most commonly used for:

• Knee osteoarthritis

•  Early cartilage wear and joint degeneration

• Meniscal Tears

It’s particularly helpful when joint pain is caused by wear and tear rather than active inflammation. If your knee is swollen we would need to settle this down with a steroid or Cingal injection first.

How Do Hyaluronic Acid Injections Work?

Hyaluronic acid is a viscous, gel-like substance found naturally in healthy joints. It acts as a lubricant and shock absorber, allowing bones to move smoothly and comfortably.

In arthritic joints, the natural concentration of hyaluronic acid is reduced. Injecting it back into the joint can:

• Replenish lost lubrication

• Reduce joint friction and stiffness

• Improve cushioning and comfort

• Delay the need for more invasive treatments

How Many Hyaluronic Acid Injections Can You Have?

There is no strict limit to the number of hyaluronic acid injections you can receive, especially when they are spaced appropriately and continue to provide benefit.

Most people receive:

• A single course every 6 to 12 months, depending on pain levels and joint condition and how you responded to your previous injection.

• Repeat injections only if symptoms return and other treatments are no longer providing sufficient relief

Hyaluronic acid can be safely repeated over time if needed. Your clinician will assess the response to each injection and discuss whether ongoing treatment is appropriate as part of your long-term joint care plan.

What to Expect During the Procedure

• First, you will have a detailed discussion with the specialist physiotherapist about your condition, followed by a thorough assessment.
• The next step is to ensure you understand the risks of the procedure and give your consent for it to happen
• The injection itself is a quick, minimally invasive procedure that usually takes around 10–15 minutes.

• Most people are able to resume light activity shortly afterwards. However we recommend up to 5 days of rest from heavy or high loaded activity following your injection.

When Are Hyaluronic Acid Injections Most Effective?

Hyaluronic acid injections are most effective when joint pain is caused by wear and tear (osteoarthritis) rather than active inflammation (swelling).

They tend to work best when:

• Osteoarthritis is mild to moderate — There’s still some joint space and cartilage present

• You have ongoing stiffness or aching, especially during or after activity

• Pain relief from oral medications or physiotherapy isn’t lasting

• You want to delay or avoid joint replacement surgery

• Steroid injections are not suitable due to side effects.

These injections are often part of a multimodal approach, working best when combined with tailored physiotherapy, joint strengthening, weight management, and activity modification.

Are Hyaluronic Acid Injections Safe?

Yes — hyaluronic acid injections are considered very safe, especially when administered by a trained professional. As it mimics a substance your body already produces, allergic reactions are rare.

Potential (but uncommon) side effects include:

• Mild swelling or discomfort at the injection site

• Temporary stiffness or aching

• Infection (very rare)

You’ll be advised on post-injection care to minimise any side effects and maximise benefit.
