What is Hyaluronic Acid and How Does it Help Knees?

Hyaluronic acid (HA) is a naturally occurring substance in your body, found in your joints, skin, and eyes. It acts as a lubricant and shock absorber. In healthy joints, HA helps cartilage move smoothly. In osteoarthritis, the cartilage breaks down, reducing the amount of HA and causing pain and stiffness. Hyaluronic acid injections for knee osteoarthritis aim to replenish this lost lubricant, easing joint pain and improving function. These injections are a type of viscosupplementation therapy.

Who is a Candidate for Hyaluronic Acid Knee Injections?

Hyaluronic acid injections are often considered for individuals with mild to moderate knee osteoarthritis who haven't found relief through other conservative treatments. This may include over-the-counter pain relievers, physical therapy, and lifestyle modifications. Your doctor will evaluate your condition and medical history to determine if this treatment is suitable for you. Factors like the severity of your osteoarthritis, your overall health, and any other medical conditions will be taken into account.

The Hyaluronic Acid Injection Procedure: What to Expect

The procedure is relatively simple and minimally invasive. It's typically performed in a doctor's office or clinic. First, the area will be cleaned and sterilized. Then, using ultrasound guidance, the doctor will inject the hyaluronic acid solution directly into your knee joint. The process usually takes only a few minutes. You may experience some mild discomfort during the injection, but it's generally well-tolerated.

What Happens After the Injection?

After the injection, you'll likely be able to walk and resume normal activities immediately. However, your doctor may recommend some rest and avoiding strenuous activities for a day or two. You might experience some mild swelling, bruising, or stiffness in your knee. These side effects are usually temporary and subside within a few days.

How Effective are Hyaluronic Acid Injections?

Studies show varying degrees of success with hyaluronic acid injections for knee osteoarthritis. While not a cure, many patients experience significant pain relief and improved mobility. The effectiveness can depend on several factors, including the severity of the osteoarthritis, the individual's response to the treatment, and the type of hyaluronic acid used. Your doctor can discuss the expected outcomes based on your specific situation.

Are There Any Potential Side Effects?

Although generally safe, hyaluronic acid injections can have some potential side effects. These are usually mild and temporary, including:

Swelling
Pain or stiffness at the injection site
Bruising
Redness
Warmth at the injection site
Rarely, more serious allergic reactions

It's crucial to inform your doctor about any allergies or medical conditions before the procedure.

How Long Do the Effects Last?

The pain relief and improved mobility provided by hyaluronic acid injections can last for several months, even up to a year in some cases. However, the duration varies from person to person. Some individuals may require repeat injections to maintain relief.

What is the Cost of Hyaluronic Acid Injections?

The cost of hyaluronic acid injections can vary depending on several factors, including your location, the type of hyaluronic acid used, and your insurance coverage. It's important to discuss the cost with your doctor and insurance provider before undergoing the procedure.
