What it is
Knee injections for arthritis are treatments delivered by a needle into or around the knee joint. They are generally aimed at easing pain and stiffness linked to wear-and-tear changes in the joint, often called osteoarthritis, or to other forms of arthritis.
Several kinds exist. Corticosteroid injections are medicines meant to calm inflammation. Hyaluronic acid injections, sometimes called gel or viscosupplement injections, use a substance similar to a natural component of joint fluid. Some clinics also offer biologic or 'regenerative' injections such as PRP, stem cell, amniotic, umbilical, or exosome products.
Regulatory status matters here. Many biologic and regenerative injections are not FDA-approved for orthopedic uses, and insurance often does not cover them. Corticosteroid and hyaluronic acid products are regulated differently, and coverage varies by plan. Ask any provider about the regulatory status of what they offer.
How it’s traditionally been approached
Arthritis of the knee has traditionally been approached in steps. Many people start with activity adjustments, weight management support, physical therapy, supportive devices, and over-the-counter or prescription medicines, as guided by a clinician.
Injections have often been considered when those everyday approaches have not given enough relief, or as a way to help someone stay active while exploring other options. How long any relief lasts varies widely from person to person, and some people notice little change.
When arthritis is advanced and daily function is greatly limited, knee replacement surgery is one option that orthopedic surgeons discuss. It is a major decision, and seeking a second opinion beforehand is common and encouraged.
How the right orthopedic doctor may help
The right orthopedic doctor may begin by listening to your story: where the knee hurts, what makes it better or worse, and what you want to be able to do. A visit often includes a physical exam and may include imaging such as X-rays, so the doctor can understand what is going on in your knee.
Based on that evaluation, a licensed clinician may explain which options could be reasonable for you and which may not be. They may also coordinate with physical medicine and rehab providers, injection specialists, or joint replacement surgeons, depending on your situation.
Helpful questions to bring: What type of injection are you suggesting, and why this one for me? Is it FDA-approved for this use? What might it cost me, and will insurance cover it? What are the possible risks and limits? What are the alternatives, including doing nothing for now? If surgery is mentioned, would you support a second opinion?
The whole-person view
Knee pain rarely stays only in the knee. Ongoing pain can affect sleep, mood, movement, and confidence, and stress and worry can in turn make pain feel more intense. Body, mind, and stress influence each other, so looking at the whole person can be valuable.
Some people find body-based support, such as the approaches offered through Somatic Experiences, helpful for how they relate to pain and tension. Others value talk therapy, such as through Therapists.plus, when pain brings frustration or low mood. These are complements to medical care, not replacements for it.

Keep in mind
- Only a licensed clinician can decide whether any injection is appropriate for you after an evaluation.
- Results, relief, and recovery times vary from person to person, and nothing is guaranteed.
- Ask about FDA status and insurance coverage, especially for PRP, stem cell, amniotic, umbilical, and exosome injections, and consider a second opinion before any major surgery.
- For sudden severe pain, a hot swollen joint with fever, or inability to bear weight, call 911 or seek emergency care; if you are in crisis, call or text 988.

Frequently asked questions
What are the main types of knee injections for arthritis?
The most commonly discussed types are corticosteroid injections, hyaluronic acid (gel) injections, and biologic or regenerative injections such as PRP or stem cell products. Each works differently and has different regulatory and coverage considerations. A licensed clinician can explain which, if any, may fit your situation.
Are knee injections for arthritis a cure?
No, they are generally not considered a cure for arthritis. They are traditionally used to help manage symptoms like pain and stiffness for a period of time. How much they help, and for how long, varies from person to person.
Are PRP and stem cell knee injections FDA-approved?
Many are not FDA-approved for orthopedic uses, including many PRP, stem cell, amniotic, umbilical, and exosome products. Insurance also often does not cover them. Ask any provider plainly about regulatory status, costs, and the reasons they recommend a particular product.
How do I find an orthopedic doctor near me for knee injections?
Start by looking for a licensed orthopedic doctor who treats knee conditions, and consider whether you want a general orthopedist, a sports medicine or injection-focused specialist, or a joint replacement surgeon. Our directory can point you to educational resources and independent providers. Ask about their experience with your type of knee concerns and what a first visit involves.
What happens at a visit to talk about knee injections?
A visit typically includes a conversation about your symptoms and goals, a physical exam, and possibly imaging like X-rays. The clinician may then explain the options they consider reasonable and their risks and limits. You can ask questions and take time to decide.
Should I get a second opinion before knee replacement?
Yes, a second opinion is commonly encouraged before any major surgery. Another orthopedic doctor may confirm, add to, or offer a different perspective on your options. It can help you feel more confident in your decision.
