Types of Knee Injections
When it comes to treating knee pain, there are several types of knee injections available. Each type has its own benefits and risks. Let’s explore the main types: corticosteroid injections, hyaluronic acid injections, platelet-rich plasma (PRP) injections, stem cell injections, and prolotherapy injections.
Corticosteroid Injections
Corticosteroid injections are the most common knee injections for managing osteoarthritis. These injections contain a medication similar to cortisol, a natural hormone that reduces inflammation. Corticosteroids can provide quick relief from pain and swelling, making them a popular choice for short-term management.
Benefits:
– Quick relief from pain and inflammation
– Improved mobility
Risks:
– Cartilage degeneration
– High blood pressure
– Blood sugar spikes
– Other side effects like headaches and infections
Doctors usually recommend waiting at least three months between injections and limiting them to 2-3 times per year per joint.
Hyaluronic Acid Injections
Hyaluronic acid (HA) injections, also known as viscosupplementation, help provide extra lubrication to the knee joint. This can improve the knee’s ability to absorb shock and reduce pain.
Benefits:
– Joint lubrication
– Pain relief
– Improved mobility
Risks:
– Swelling and tenderness at the injection site
– Lack of long-term research support
The American College of Rheumatology and Arthritis Foundation do not currently recommend HA injections due to insufficient research.
Platelet-Rich Plasma (PRP) Injections
PRP therapy uses your own blood to help regenerate damaged tissues. The blood is processed to concentrate platelets, which are then injected into the knee.
Benefits:
– Relief from swelling, pain, and stiffness
– Increased mobility and function
– Improved quality of life
Risks:
– Experimental treatment
– More research needed to confirm effectiveness
PRP is considered an off-label treatment and is not typically covered by insurance.
Stem Cell Injections
Stem cell injections are an experimental treatment that aims to regenerate damaged cartilage and reduce inflammation. These unique cells can develop into different types of cells needed for tissue repair.
Benefits:
– Potential for cartilage regeneration
– Long-term pain relief
– Reduced inflammation
Risks:
– Experimental and not FDA-approved
– Requires more research to confirm effectiveness
Stem cells are usually obtained from your bone marrow or fat tissue and injected into the knee.
Prolotherapy Injections
Prolotherapy involves injecting a dextrose solution into the knee to stimulate tissue repair. It is often used for ligament and tendon pain and chronic injuries.
Benefits:
– Potential pain relief for chronic injuries
– Limited risks
Risks:
– More research needed to confirm effectiveness
– Possible side effects like infection or allergic reactions
Prolotherapy could be a viable option if other treatments have not worked.

How Knee Injections Work
Anesthetic and Fluid Removal
Before administering a knee injection, doctors often use an anesthetic to numb the area. This numbing agent, like lidocaine or bupivacaine, helps to minimize discomfort during the procedure. Dr. Anuj Malhotra explains, “The anesthetic serves two purposes: to immediately block your pain and to signal to the doctor that your knee itself was the cause of the discomfort.”
Fluid removal, or aspiration, is another crucial step. If there’s excess fluid in the knee joint, it can cause swelling and pain. Removing this fluid helps to relieve pressure and makes the injection more effective.
Injection Process
The actual injection process is straightforward but requires precision. A mixture of medication is injected into the knee joint. This can include corticosteroids, hyaluronic acid, PRP, or stem cells, depending on the treatment plan.
Needle placement is critical for effectiveness. Doctors often use ultrasound guidance or fluoroscopy (a type of real-time X-ray) to ensure the needle is correctly positioned. Dr. Malhotra notes, “The injection can also be done with ultrasound guidance to increase accuracy and also to improve patient comfort.”
Pain Relief Mechanism
The pain relief mechanisms of knee injections vary depending on the type of injection:
Corticosteroid Injections: These reduce inflammation quickly, providing relief within 24 to 48 hours. However, the effects are usually short-term, lasting about 6 to 12 weeks.
Hyaluronic Acid Injections: These act as a lubricant and shock absorber in the joint, improving mobility and reducing pain over several weeks. The effects can last several months.
PRP Injections: Platelet-rich plasma helps to heal tissue by stimulating growth factors. Pain relief and improved function typically occur within two to six weeks.
Stem Cell Injections: These aim to regenerate cartilage and repair damaged tissue. Although results can take time, many people experience significant improvement within two to six weeks.
The combination of numbing, fluid removal, and precise medication delivery aims to provide effective and targeted pain relief, improving overall knee function.

Benefits and Risks of Knee Injections
Benefits
Quick Relief: One of the primary benefits of knee injections is the rapid relief they can provide. Corticosteroid injections, for example, often offer immediate pain reduction and decreased inflammation. This can be particularly beneficial for those needing quick pain management for daily activities or special events.
Long-Term Pain Management: Some knee injections, like hyaluronic acid injections, can offer pain relief that lasts several months. These injections act as a lubricant and shock absorber, which can help reduce pain and improve joint function over time.
Improved Mobility: Many people experience significant improvements in mobility after receiving knee injections. By reducing pain and inflammation, these treatments can help you move more freely and participate in activities you might have been avoiding.
Versatility: Knee injections can be tailored to fit various needs. For instance, platelet-rich plasma (PRP) injections and stem cell injections are often used for more chronic conditions and aim to repair and regenerate damaged tissues. This makes them suitable for a broad range of knee issues.
Risks
Joint Swelling and Pain: One of the most common side effects is joint swelling and pain at the injection site. This discomfort usually subsides within a few days, but it’s essential to monitor your symptoms and consult your doctor if they persist.
Infection: Although rare, there is a risk of infection any time a needle is inserted into the body. This risk can be minimized by following post-injection care instructions, such as avoiding swimming and hot tubs for 24 hours.
Cartilage Damage: Repeated corticosteroid injections can potentially lead to cartilage damage over time. It’s crucial to discuss the frequency and long-term impact of these injections with your doctor to avoid potential adverse effects.
Allergic Reactions: Some injections, particularly those made from animal products, can cause allergic reactions. For example, most hyaluronic acid injections are derived from rooster combs and should be avoided by individuals with poultry allergies. However, options like Euflexxa are safe for those with egg allergies.
Frequency of Injections: The effectiveness of knee injections can diminish over time. Most doctors recommend limiting certain injections, like hyaluronic acid, to a maximum of twice per year to maintain their efficacy and reduce the risk of side effects.
Understanding the benefits and risks of knee injections can help you make an informed decision about your treatment options. Always consult with a healthcare professional to develop a personalized plan that suits your specific needs.

Frequently Asked Questions about Knee Injections
What is the most effective knee injection?
The effectiveness of knee injections can vary based on individual needs and conditions. However, cortisone shots are often considered highly effective for reducing inflammation and providing pain relief. According to Dr. John Richmond, an orthopedic surgeon, cortisone injections offer “very rapid” relief, usually within 24 to 48 hours. They work by reducing inflammation in the joint, which helps to alleviate pain and swelling.
What is the new injection treatment for knees?
One of the newer treatments for knee pain is hyaluronic acid injections. These injections act as a lubricant and shock absorber for the knee joint. Hyaluronic acid is a natural component of joint fluid, but in osteoarthritis, its levels can diminish. Injecting additional hyaluronic acid can help improve joint lubrication and reduce pain. Studies have shown that hyaluronic acid injections can provide pain relief and improve mobility, although the effects may take several weeks to become noticeable.
What are the three injections for knee pain?
The three most common types of injections for knee pain are:
Corticosteroid Injections: These are effective for quick relief of inflammation and pain. They are especially useful during flare-ups of osteoarthritis, offering relief that can last from 6 to 12 weeks.
Hyaluronic Acid Injections: Also known as viscosupplementation, these injections improve joint lubrication and can provide pain relief for several months. They are often recommended for those who haven’t found relief from other treatments.
Platelet-Rich Plasma (PRP) Injections: PRP injections use a concentration of a patient’s own platelets to promote healing and reduce pain. This treatment is gaining popularity for its potential in regenerative medicine, although it may take several weeks to see improvement.
In addition to these, stem cell injections are another option being explored. These injections aim to regenerate cartilage and provide long-term benefits, although they are still considered experimental.
For more comprehensive insights into these treatments, consult with your healthcare provider to determine which option best suits your condition and lifestyle.
