Hyaluronic Acid Injection

What Is a Hyaluronic Acid Injection?

Hyaluronic acid is a substance that naturally exists in your joint fluid. It helps cushion and lubricate your joints so they can move smoothly. When arthritis reduces this natural cushioning, a hyaluronic acid injection may help improve joint movement and decrease pain. This treatment is most commonly used for knee arthritis and is sometimes called viscosupplementation.

Why Might I Need This Injection?

Your provider may recommend this treatment if you have:

• Knee osteoarthritis
• Ongoing knee pain that has not improved with medications, physical therapy, or other nonsurgical treatments
• Stiffness that makes walking or daily activities difficult

Not everyone is a candidate, and results can vary from person to person.

What Happens During the Procedure?

The injection is performed in the office and usually takes only a few minutes. During the procedure:

• The skin is cleaned to reduce infection risk.
• A small needle is placed into the joint space.
• The hyaluronic acid is injected into the joint.
• The joint may be gently moved to help distribute the medication.

You may feel mild pressure or discomfort, but the procedure is generally well tolerated.

When Will I Feel Relief?

Pain relief is not immediate. It may take several weeks to notice improvement. Some patients experience relief for several months.

Possible Benefits

Hyaluronic acid injections may:

• Improve joint lubrication
• Reduce pain
• Improve mobility and flexibility
• Delay the need for surgery in some cases

What Are the Risks?

Most patients tolerate the injection well. Possible side effects include:

• Temporary soreness or swelling at the injection site
• Mild joint stiffness
• Rare allergic reaction
• Rare infection

Call your provider if you experience severe swelling, fever, or increasing pain.

Related Treatments
