Understanding Knee Pain and Why PRP Is Different
PRP injections for the knee have gained attention because they don’t just mask pain—they work with your body to heal it. Knee pain is one of the most common complaints people face, often caused by osteoarthritis, sports injuries, or general wear and tear on the joint. Over time, cartilage can break down, leading to stiffness, swelling, and difficulty moving comfortably.
Standard treatments like NSAIDs, physical therapy, or even steroid injections may provide relief, but it’s usually temporary. They reduce symptoms without addressing the underlying damage inside the joint.
That’s where PRP—platelet-rich plasma—steps in. Unlike other therapies, PRP uses your own blood to create a concentrated solution of healing growth factors. When injected into the knee, it encourages the body to repair tissues, reduce inflammation, and restore function naturally.
What Are PRP Injections?
PRP stands for platelet-rich plasma, a substance created from your own blood. A small sample of blood is drawn and spun in a centrifuge to separate the platelets from the rest of the fluid. These platelets are packed with proteins and growth factors responsible for healing.
When injected into the knee, PRP can stimulate repair of cartilage, tendons, and other soft tissues. Unlike painkillers or steroids, which simply mask discomfort, PRP aims to improve the health of the joint itself.
This is why PRP is considered a regenerative therapy. It’s not just about reducing symptoms—it’s about giving your knee the tools it needs to heal from within.
How the PRP Procedure Works
Step 1: Blood Draw
The process starts with a quick blood draw, similar to a routine lab test.
Step 2: Centrifuge Separation
Your blood sample is placed in a centrifuge, which spins it rapidly to separate the platelet-rich plasma from the rest of the blood.
Step 3: Injection Into the Knee
The concentrated PRP is then carefully injected into the affected knee joint. Many providers use ultrasound guidance to ensure precise placement of the injection for maximum effectiveness.
Number of Sessions
The number of treatments depends on your condition, but many patients see results with a series of one to three injections spaced weeks apart. Some notice improvement after a single session, while others benefit from a full treatment plan.
Benefits of PRP for Knee Pain
PRP injections for the knee offer a unique approach because they use the body’s own biology to support healing instead of relying on synthetic drugs or temporary fixes.
Natural Healing, No Foreign Substances
Since PRP is made from your own blood, there are no additives or foreign substances. That makes it one of the most natural options available.
Helps Repair Cartilage and Soft Tissue
The concentrated platelets deliver growth factors that stimulate repair of cartilage, tendons, and other joint structures that often break down with arthritis or injury.
Reduces Pain and Inflammation
By calming inflammation inside the joint, PRP can ease pain without the long-term risks of anti-inflammatory medications.
Improves Mobility and Joint Function
Patients often report less stiffness and better flexibility, making daily activities—like walking, exercising, or climbing stairs—easier again.
May Delay or Prevent Surgery
For many, PRP can help maintain joint health long enough to delay or even avoid the need for knee replacement surgery.
Who Is a Good Candidate for PRP?
PRP isn’t right for everyone, but it can be very effective in the right situations.
Mild to Moderate Osteoarthritis
Patients in the earlier stages of arthritis often see the best results because there’s still enough cartilage for PRP to support repair.
Athletes with Sports-Related Knee Injuries
Meniscus tears, ligament strains, and cartilage injuries may respond well to PRP since it supports tissue healing.
Non-Surgical Seekers
If you’re not ready—or don’t want—to undergo surgery, PRP provides a regenerative, minimally invasive option.
When PRP May Not Be Recommended
It may not be suitable for severe arthritis where cartilage is completely worn away, or for patients with bleeding disorders, active infections, or certain medical conditions.
Comparing PRP to Other Knee Treatments
Not sure how PRP fits with other options? Here’s how it stacks up.
PRP vs. Corticosteroid Injections
Steroid shots can quickly reduce inflammation but don’t promote healing. PRP takes longer to show results but works to repair tissue for longer-term benefits.
PRP vs. Hyaluronic Acid Injections
Hyaluronic acid adds lubrication to the knee joint for smoother movement, while PRP works to regenerate and repair. Sometimes, physicians even recommend combining the two for optimal results.
When PRP Might Be the Better Option
If your goal is to heal damaged tissue and support long-term joint health—not just mask symptoms—PRP may be the stronger choice.
What to Expect After PRP Treatment
Recovery Timeline
After PRP injections for the knee, most patients can go home the same day. You’ll want to take it easy for a few days—avoid heavy lifting, running, or high-impact sports. Light movement and gentle walking are usually fine and can even help with circulation.
Pain Relief Timeline
PRP is not an instant fix. Because it works by stimulating healing, it can take several weeks before you start noticing improvements. Many patients see gradual relief that continues to build over time.
Duration of Benefits
Results often last 6 to 12 months, and in some cases even longer. This makes PRP one of the more sustainable non-surgical treatments for knee pain.
Importance of Follow-Up Care
Your physician will schedule follow-up visits to track progress. Some patients benefit from additional injections spaced months apart, depending on the severity of their condition and their goals.
Frequently Asked Questions About PRP Injections
Most patients notice improvement within 4 to 6 weeks, though it may take longer for full benefits to appear.
Some people do well with just one session, while others may need a series of two to three injections spaced weeks apart for best results.
PRP is not specifically FDA-approved for knee pain, but it is widely used and supported by growing research in regenerative medicine. Since PRP is made from your own blood, it is generally considered safe.
