Types of knee pain injections and how they differ

Physicians who treat knee pain use several categories of injections. The main ones are:

• Corticosteroids (cortisone): Anti-inflammatory medicines injected directly into the joint. They are among the most commonly used options for reducing swelling and discomfort.
• Hyaluronic acid (viscosupplementation): A gel-like substance that may help cushion the joint. It is sometimes used when corticosteroids have not provided lasting relief.
• Regenerative options such as PRP (platelet-rich plasma): These use components drawn from your own blood. They are offered at many clinics, but availability and whether they are appropriate for a given person depends on the individual case.
• Stem cell and other regenerative products: These are discussed more in a section below because they carry specific regulatory considerations.

Which category, if any, is right for you depends on the cause of your knee pain, your medical history, and other factors a physician needs to review in person.

What to expect after a cortisone (corticosteroid) injection in the knee

After a cortisone injection, some people notice a short-term increase in pain. This is called a cortisone flare or steroid flare, and it can occur in the first day or two after the shot. It is a recognized response based on general medical consensus. Applying ice to the area and resting the joint are common recommendations during this period, though your physician will give you specific instructions.

Clinicians typically limit how often corticosteroid injections are given in a single joint over time. If you are wondering whether another injection is appropriate or when, that is a question for your physician based on your full history.

When pain after a cortisone shot is normal versus a reason to call

Short-term soreness in the first couple of days can be a normal response. However, some signs point to a problem that needs prompt attention. Contact a physician right away if you notice:

• Fever
• Spreading redness around the injection site
• Unusual warmth or swelling in the knee
• Drainage or fluid coming from the injection site

These can be signs of infection, which requires prompt medical attention according to general medical consensus. This page cannot tell you what is causing your specific symptoms. If you are concerned, call your treating physician or seek care right away.

What to know before considering stem cell or regenerative injections

You may have seen advertising for stem cell injections for knee pain in the Los Angeles area. Before pursuing these treatments, there are facts worth knowing.

The U.S. Food and Drug Administration has not approved stem cell or other regenerative products for most orthopedic and joint uses. The FDA actively warns the public about unapproved stem cell and regenerative medicine products. That does not mean every clinic offering these products is operating illegally, but it does mean you should ask specific questions before proceeding.

PRP (platelet-rich plasma) injections are a separate category and are offered at many licensed clinics. As with stem cell products, their appropriateness varies by individual. A physician evaluation is the starting point for any regenerative option.

Questions to ask at your evaluation in the Los Angeles area

When you meet with a physician to discuss knee injections, consider asking:

1. What is likely causing my knee pain, and which injection category, if any, makes sense for my situation?
2. Is the physician performing the injection licensed by the Medical Board of California? (California physicians are required to hold a valid license from the Medical Board of California to practice medicine in the state.)
3. If you are recommending a regenerative product, is it FDA-approved or is it used under another regulatory pathway?
4. How many injections might be needed, and are there limits on how often they can be given?
5. What are the realistic risks associated with this injection for someone in my situation?
6. What follow-up or additional care would you recommend alongside the injection?

How a pain evaluation works at our clinic

At Axis Pain & Anesthesia Group, an evaluation starts with a conversation about your pain history, what makes it better or worse, and what you have already tried. The physician reviews any relevant imaging or prior records you bring. A physical exam of the knee follows.

Based on that information, the physician discusses which options may be appropriate for your specific situation. No injection is scheduled without that review. You leave the visit with a clear picture of what was found and what your options are.
