Hyaluronic Acid

Hyaluronic Acid Injections

Hyaluronic acid injections are a treatment option used to help relieve pain and stiffness caused by osteoarthritis, most commonly in the knee. They are designed to improve joint lubrication and cushioning, making movement more comfortable.

What is hyaluronic acid?

Hyaluronic acid is a substance that is naturally found in healthy joints, where it acts as a lubricant and shock absorber. In osteoarthritis, the amount and quality of hyaluronic acid in the joint can decrease, leading to increased friction, pain, and stiffness.

How do hyaluronic acid injections work?

Hyaluronic acid injections are given directly into the joint. Once injected, they help to:

  • Improve lubrication within the joint

  • Reduce friction between joint surfaces

  • Improve shock absorption

This can result in reduced pain, less stiffness, and improved movement, especially during everyday activities such as walking, climbing stairs, or standing for longer periods.

What are the benefits?

Hyaluronic acid injections:

  • Mimic the joint’s natural fluid

  • Provide gradual pain relief rather than immediate symptom masking

  • Can improve mobility and joint function

  • Offer a non-surgical treatment option

Relief usually develops over several weeks and may last for several months, although results vary between individuals.

What to expect after the injection

Some patients may experience temporary soreness, swelling, or stiffness in the joint following the injection. These symptoms are usually mild and settle within a few days. Most people can return to normal daily activities shortly after treatment, though high-impact exercise may be limited for a short time.

Who may benefit from hyaluronic acid injections?

These injections are often considered for people who continue to have joint pain despite treatments such as physiotherapy, exercise programmes, weight management, or pain-relief medication. They may be suitable for those who want to delay or avoid surgery.
