What is Hyaluronic Acid and How Does It Work?

Hyaluronic acid is a polysaccharide naturally found in the body that helps maintain tissue elasticity and hydration. In joints, it functions as a lubricant and protective cushion, reducing friction and mechanical stress. Over time, or due to pathological conditions, the quantity and quality of hyaluronic acid decrease, leading to stiffness, pain, and inflammation.

Hyaluronic acid injections aim to restore this balance by enhancing the synovial fluid and improving joint function.

When Are Hyaluronic Acid Injections Recommended?

These injections are primarily recommended for patients with mild to moderate osteoarthritis, as well as for individuals who:

• Do not respond well to conservative treatments (pain relievers, physical therapy).
• Want to delay or avoid surgery (such as joint replacement).
• Seek an alternative way to manage pain and inflammation.

Procedure and Administration

The procedure is relatively simple and performed in a medical office under aseptic conditions:

1. Cleansing the area: The doctor disinfects the skin around the joint.
2. Aspiration of excess fluid (if necessary): In some cases, the doctor may remove excess synovial fluid before injection.
3. Injection of hyaluronic acid: The solution is injected directly into the joint using a fine needle.

Benefits and Effectiveness

Short-Term Benefits

• Immediate pain relief.
• Improved joint mobility.
• Reduced inflammation.

Long-Term Benefits

• Slowed progression of osteoarthritis.
• Delayed need for surgery.
• Improved quality of life.

Most patients report improvement within the first few weeks, with results lasting from 6 to 12 months, depending on the severity of the condition and the type of hyaluronic acid used.

Possible Side Effects and Contraindications

Hyaluronic acid injections are generally safe, but they may cause:

• Mild pain or swelling at the injection site.
• Temporary stiffness.
• Rare allergic reactions or infections.

They are contraindicated in cases of:

• Active joint infections.
• Severe advanced arthritis requiring surgery.
• Allergy to hyaluronic acid or its components.

Conclusion

Intra-articular hyaluronic acid injections are an effective option for managing osteoarthritis and chronic joint pain. When appropriately selected and administered, they can provide significant relief and improve mobility while delaying the need for surgery. Before undergoing this treatment, it is essential to consult with a doctor to determine if this method is suitable for you.
