Intra-Articular Knee Injection: Procedure, Benefits, and What to Expect

What Is an Intra-Articular Knee Injection?

An intra-articular knee injection is a treatment where medicine is injected directly into the knee joint. Doctors often use this procedure to help reduce pain and swelling. Many people with knee pain, especially from arthritis, find relief with these injections. In fact, the intra-articular knee injection procedure is common for those who have not improved with other treatments.

Common Reasons for the Procedure

Doctors may suggest knee pain relief injections for several reasons. Usually, these injections help people who have:

Osteoarthritis (wear and tear of the knee joint)

Rheumatoid arthritis (joint swelling from immune system problems)

Gout (joint pain from uric acid crystals)

Swelling or pain after a knee injury

Other types of joint inflammation

Sometimes, doctors use these injections to help diagnose the cause of knee pain as well.

Step-by-Step Overview of the Procedure

Knowing what to expect during an intra-articular knee injection can help you feel more at ease. Here is a simple step-by-step guide:

First, your doctor will clean the skin around your knee.

Next, they may use a numbing spray or medicine to reduce discomfort.

Then, the doctor will insert a thin needle into the knee joint.

After that, the medicine is injected directly into the joint space.

Finally, the doctor may place a small bandage over the spot.

The whole process usually takes less than 15 minutes. Most people can go home soon after the injection.

Benefits and Expected Outcomes

Many people ask about the benefits of knee pain relief injections. These injections can:

Reduce pain and swelling quickly

However, results can vary. Some people feel better within a few days, while others may take longer. In some cases, the relief may last for several weeks or even months.

What to Expect Before, During, and After the Injection

During the injection, you might feel a quick pinch or pressure, but most people find it tolerable. After the injection, you can usually walk and return home right away.
